How to Write a Compare-and-Contrast Essay

A compare-and-contrast essay is a style of essay that points out the similarities and differences between two or more subjects. It’s ideal for showing what separates and unites related things or concepts, particularly if the subjects are often confused for each other or unjustly lumped together. 

Compare-and-contrast essays have a lot in common with other essay types, but differ in many ways, too—and that’s the heart of comparing and contrasting! By seeing the differences and similarities, the reader better understands each of the subjects by using the other subject as a frame of reference.

In this guide, we explain how to write a compare-and-contrast essay, including some advanced tips and examples. We discuss how to structure your essay and how to frame your thesis , but first, let’s take a broader look at why comparison essays are so useful. 

Purpose of a compare-and-contrast essay

Let’s say you want to write an essay about how great renewable resources are, but you spend a lot of your time explaining how fossil fuels work. To truly understand why renewable resources are so amazing, your reader needs a little background on their alternative, fossil fuels—but the essay’s attention is divided so equally that it’s like there are two topics. 

That’s when compare-and-contrast essays function at their best. If two topics relate to each other or define each other, you can better explain them both by showcasing their similarities and differences. That goes double for topics that are often conflated or confused for each other; it helps readers when someone points out exactly what’s the same about them and what’s different. 

Unlike argumentative essays or persuasive essays , compare-and-contrast essays deal with multiple topics instead of focusing on one. The downside is that they don’t describe the individual subjects as much as single-topic essays. They’re also a common assignment for college essays since they show the instructor how well you grasp both subjects. 

How to write a compare-and-contrast essay 

When writing a compare-and-contrast essay, it helps to figure out two things: what your thesis is (the subject matter) and how you plan to structure it. 

First things first: You need to choose which subjects you’re comparing. This isn’t always easy, especially if you have to pick the subjects on your own. 

For inspiration, here are some compare-and-contrast essay example topics:

• fossil fuels and renewable resources
• Coca-Cola and Pepsi 
• Mona Lisa and The Girl with a Pearl Earring
• ’80s punk rock music and ’90s grunge music
• Dorothea Lange and Diane Arbus
• London in the 1600s and London now
• the LGBTQIA+ community before and after Stonewall
• Roman Empire and Greek Empire
• loop quantum gravity and string theory
• evolution and creationism
• liberalism and conservatism
• fascism and despotism

Once you’ve settled on your subjects, you can begin generating ideas. It helps to first list all the similarities and differences between your subjects . When you see them all written down, you can start formulating connections and decide what structure to use for your compare-and-contrast essay. 

If you’re stuck, try making a Venn diagram . This is a visual aid that helps you understand which characteristics your subjects share, and which ones are exclusive. 

Looking at your lists, you can then decide on the thesis. To do so, ask yourself a few questions: What are you trying to show in your compare-and-contrast essay? What do you want your reader to take away? For example, do you want to emphasize that Dorothea Lange’s work influenced Diane Arbus, or that they are two very distinct artists? 

Organization

Compare-and-contrast essays follow our own recommended essay structure . While the linked guide goes into more detail, in a nutshell, your compare-and-contrast essay should follow a simple format of beginning, middle, and end: 

• Introduction: where you explain your thesis or what your essay will discuss
• Body: where you actually list the similarities and differences of your subjects; the largest section
• Conclusion: where you wrap up and summarize your points

The introduction, usually one or two paragraphs, should include a thesis statement to show the reader what to expect for the rest of your essay. You can write your introduction following the same guidelines as other essay types, though be sure to mention all your subjects. Likewise, you can write an essay conclusion with the standard rules and best practices. 

It’s the body where compare-and-contrast essays get tricky. Do you write about both subjects at the same time, or switch back and forth? Let’s talk deeper on this below. 

How to structure a compare-and-contrast essay

The hardest part of structuring a compare-and-contrast essay is knowing when to talk about which subject. Essentially, you have three options: 

• block method (subject by subject): You discuss one subject in full and then move on to the next subject.
• alternating method (point by point): You discuss one subject’s take on a certain aspect and then another subject’s take immediately afterward, followed by a new aspect.
• similarities and differences: You discuss all the similarities between your subjects and then all the differences, or vice versa (differences first and then similarities).

No matter which option you choose, you have to pay particular attention to topic sentences . Paragraphs in compare-and-contrast essays can get complicated, so it’s crucial to have a good topic or introduction sentence for each paragraph to make the flow of ideas clear. 

Block method (subject by subject)

The block method is usually divided into paragraphs: a paragraph about one subject and then a new paragraph about another subject. Take the compare-and-contrast essay example When Nothing Lies Beyond the Mask: Comparing Moby Dick and The Raven . In the first paragraph after the introduction, the author talks only about Ahab from Moby Dick , but in the next paragraph talks only about the narrator from The Raven . Each subject gets its own paragraph. 

Using the block method, you can go back and forth like this for pages, covering as many topics as you need. This approach is best for giving each subject its own attention but tends to slightly weaken the connection between the two. 

Alternating method (point by point)

As another option, you can break paragraphs up by a specific topic and issue, and in each paragraph discuss both or all subjects. Let’s look at another compare-and-contrast essay example, The Reality of Science Fiction: Comparing Clarke to Cruise . Here, both subjects are discussed in the same paragraph, one right after another. 

This approach works best when you want to emphasize the connection between your subjects, or lack thereof. In our example above, the author wishes to highlight just how different the aliens of Arthur Clarke are from those of other authors, particularly H. G. Wells. To emphasize this, the essay author juxtaposes the two points right next to each other in the same paragraph. 

Similarities and differences

The third option is quite similar to the alternating approach, with each subject being discussed side by side in the same paragraph. However, the paragraphs aren’t divided by different topics, but instead by what the subjects have in common and what they don’t. 

Take a look at the compare-and-contrast essay example Government by the People, for the People has Perished from the Earth , which compares the dystopias of George Orwell’s 1984 and Yevgeny Zamyatin’s We . The first paragraph after the introduction discusses what the governments in the two books have in common, but the next paragraph explains how they differ. 

This method works best if you want to focus on a particular similarity or difference between your subjects, or if you want to build up to a powerful conclusion or reveal at the end. 

The writing process for compare-and-contrast essays

Want to know how to write a compare-and-contrast essay step by step? The writing process is the same as all essay writing, although adapted specifically for drawing comparisons:

1   Brainstorming — As mentioned above, brainstorming should involve listing all the similarities and difficulties; creating a Venn diagram is a useful method. 

2   Preparation — Looking at your brainstorming lists, decide which structuring method would best get your point across: block, alternating, or similarities/differences. 

3   Drafting — Here you write your rough draft ; this is the longest and toughest phase. 

4   Revising — Does the structure you’ve chosen work? With the first draft finished, you can more easily identify any areas that need to be fixed, revised, or rewritten from scratch. 

5   Proofreading — Finally, you want to make sure you corrected all the spelling and grammatical mistakes in your draft. With a writing assistant like Grammarly, this phase is a breeze.

Tips for writing compare-and-contrast essays 

Beyond knowing the full process for crafting a compare-and-contrast essay, it helps to learn a few tips to ensure it shines.

Choose topics that are related 

In other words, choose topics that have plenty in common, otherwise, your essay will be all contrasting and no comparing. Typically, subjects in compare-and-contrast essays share a strong connection, such as two people in the same profession or two products in the same category. 

Without this unifying thread, the reader is left wondering, “What’s the point of comparing these two things?” Not only will it confound your audience, but you’ll also struggle more to come up with points when writing. Solve these problems before they start by smartly choosing your subjects at the beginning. 

Write for clarity

Essays with only one subject can be confusing enough—imagine how complicated it gets with two or more subjects. One of the biggest obstacles with compare-and-contrast essays is communicating clearly so your reader knows which points relate to which subject, and what conclusion the entire essay is building toward. 

But when you’re in the heat of a writing session, it can be difficult—and distracting—to stop and evaluate your work for clarity. Luckily, Grammarly offers suggestions to rewrite entire sentences in order to improve the clarity of your writing.

If the writing in your compare-and-contrast essay starts getting messy, Grammarly’s writing suggestions recommend alternative phrasings to clear things up. Just one click and your writing gets the professional editor treatment. Try Grammarly now and see how your writing improves.

Choosing the Right Topics

When it comes to writing a compare and contrast essay, choosing the right topics is crucial. The topics you select will determine the focus of your essay and set the tone for the rest of your writing. Here are some tips for choosing the right topics:

• Choose topics that have a clear connection: Make sure the topics you choose have some similarities and differences that you can explore in your essay. This will help you create a meaningful comparison.
• Opt for topics that interest you: Select topics that you find engaging and meaningful. This will make the writing process more enjoyable and will help you stay motivated throughout.
• Consider your audience: Think about who will be reading your essay and choose topics that will resonate with them. Consider their interests and preferences when selecting your topics.
• Avoid overly broad topics: Make sure the topics you choose are specific enough to allow for a focused comparison. Overly broad topics can lead to a lack of depth in your analysis.
• Look for unique angles: Try to find topics that offer a fresh perspective or unique angle for comparison. This will make your essay more interesting and engaging to your readers.

Gathering and Organizing Information

Before you start writing a compare and contrast essay, it is essential to gather and organize all the necessary information. Begin by selecting the subjects you want to compare and contrast. Make sure they have enough similarities and differences to make your essay informative and engaging.

Once you have chosen your topics, gather relevant information from credible sources. This can include books, academic journals, articles, and reputable websites. Take detailed notes and highlight key points that you can use in your essay. Organize your information in a systematic way to make it easier to reference and use while writing.

Consider creating a T-chart or Venn diagram to visually map out the similarities and differences between your subjects. This can help you see the relationships between the two topics more clearly and guide your essay structure.

By effectively gathering and organizing information, you will set a strong foundation for your compare and contrast essay and ensure that your arguments are well-supported and coherent.

Developing a Strong Thesis Statement

One of the key elements of a successful compare and contrast essay is a strong thesis statement. Your thesis statement should clearly outline the main points you will compare and contrast in your essay. It should also convey your overall argument and the significance of the comparison.

When should i compare and contrast, making effective comparisons, comparing and contrasting as a brainstorming tool, structuring your comparisons, other interesting articles, frequently asked questions about comparing and contrasting.

Many assignments will invite you to make comparisons quite explicitly, as in these prompts.

• Compare the treatment of the theme of beauty in the poetry of William Wordsworth and John Keats.
• Compare and contrast in-class and distance learning. What are the advantages and disadvantages of each approach?

Some other prompts may not directly ask you to compare and contrast, but present you with a topic where comparing and contrasting could be a good approach.

One way to approach this essay might be to contrast the situation before the Great Depression with the situation during it, to highlight how large a difference it made.

Comparing and contrasting is also used in all kinds of academic contexts where it’s not explicitly prompted. For example, a literature review involves comparing and contrasting different studies on your topic, and an argumentative essay may involve weighing up the pros and cons of different arguments.

As the name suggests, comparing and contrasting is about identifying both similarities and differences. You might focus on contrasting quite different subjects or comparing subjects with a lot in common—but there must be some grounds for comparison in the first place.

For example, you might contrast French society before and after the French Revolution; you’d likely find many differences, but there would be a valid basis for comparison. However, if you contrasted pre-revolutionary France with Han-dynasty China, your reader might wonder why you chose to compare these two societies.

This is why it’s important to clarify the point of your comparisons by writing a focused thesis statement . Every element of an essay should serve your central argument in some way. Consider what you’re trying to accomplish with any comparisons you make, and be sure to make this clear to the reader.

Comparing and contrasting can be a useful tool to help organize your thoughts before you begin writing any type of academic text. You might use it to compare different theories and approaches you’ve encountered in your preliminary research, for example.

Let’s say your research involves the competing psychological approaches of behaviorism and cognitive psychology. You might make a table to summarize the key differences between them.

Or say you’re writing about the major global conflicts of the twentieth century. You might visualize the key similarities and differences in a Venn diagram.

These visualizations wouldn’t make it into your actual writing, so they don’t have to be very formal in terms of phrasing or presentation. The point of comparing and contrasting at this stage is to help you organize and shape your ideas to aid you in structuring your arguments.

When comparing and contrasting in an essay, there are two main ways to structure your comparisons: the alternating method and the block method.

The alternating method

In the alternating method, you structure your text according to what aspect you’re comparing. You cover both your subjects side by side in terms of a specific point of comparison. Your text is structured like this:

Mouse over the example paragraph below to see how this approach works.

One challenge teachers face is identifying and assisting students who are struggling without disrupting the rest of the class. In a traditional classroom environment, the teacher can easily identify when a student is struggling based on their demeanor in class or simply by regularly checking on students during exercises. They can then offer assistance quietly during the exercise or discuss it further after class. Meanwhile, in a Zoom-based class, the lack of physical presence makes it more difficult to pay attention to individual students’ responses and notice frustrations, and there is less flexibility to speak with students privately to offer assistance. In this case, therefore, the traditional classroom environment holds the advantage, although it appears likely that aiding students in a virtual classroom environment will become easier as the technology, and teachers’ familiarity with it, improves.

The block method

In the block method, you cover each of the overall subjects you’re comparing in a block. You say everything you have to say about your first subject, then discuss your second subject, making comparisons and contrasts back to the things you’ve already said about the first. Your text is structured like this:

• Point of comparison A
• Point of comparison B

The most commonly cited advantage of distance learning is the flexibility and accessibility it offers. Rather than being required to travel to a specific location every week (and to live near enough to feasibly do so), students can participate from anywhere with an internet connection. This allows not only for a wider geographical spread of students but for the possibility of studying while travelling. However, distance learning presents its own accessibility challenges; not all students have a stable internet connection and a computer or other device with which to participate in online classes, and less technologically literate students and teachers may struggle with the technical aspects of class participation. Furthermore, discomfort and distractions can hinder an individual student’s ability to engage with the class from home, creating divergent learning experiences for different students. Distance learning, then, seems to improve accessibility in some ways while representing a step backwards in others.

Note that these two methods can be combined; these two example paragraphs could both be part of the same essay, but it’s wise to use an essay outline to plan out which approach you’re taking in each paragraph.

Some essay prompts include the keywords “compare” and/or “contrast.” In these cases, an essay structured around comparing and contrasting is the appropriate response.

Comparing and contrasting is also a useful approach in all kinds of academic writing : You might compare different studies in a literature review , weigh up different arguments in an argumentative essay , or consider different theoretical approaches in a theoretical framework .

Your subjects might be very different or quite similar, but it’s important that there be meaningful grounds for comparison . You can probably describe many differences between a cat and a bicycle, but there isn’t really any connection between them to justify the comparison.

You’ll have to write a thesis statement explaining the central point you want to make in your essay , so be sure to know in advance what connects your subjects and makes them worth comparing.

Comparisons in essays are generally structured in one of two ways:

• The alternating method, where you compare your subjects side by side according to one specific aspect at a time.
• The block method, where you cover each subject separately in its entirety.

It’s also possible to combine both methods, for example by writing a full paragraph on each of your topics and then a final paragraph contrasting the two according to a specific metric.

Comparing and Contrasting: A Guide to Improve Your Essays

By Walter Akolo

Essays that require you to compare and contrast two or more subjects, ideas, places, or items are common.

They call for you to highlight the key similarities (compare) and differences (contrast) between them.

This guide contains all the information you need to become better at writing comparing and contrasting essays.

This includes: how to structure your essay, how to decide on the content, and some examples of essay questions.

Let’s dive in.

What Is Comparing and Contrasting?

Is compare and contrast the same as similarities and differences, what is the purpose of comparing and contrasting, can you compare and contrast any two items, how do you compare and contrast in writing, what are some comparing and contrasting techniques, how do you compare and contrast in college level writing, the four essentials of compare and contrast essays, what can you learn from a compare and contrast essay.

At their most basic, both comparing and contrasting base their evaluation on two or more subjects that share a connection.

The subjects could have similar characteristics, features, or foundations.

But while a comparison discusses the similarities of the two subjects, e.g. a banana and a watermelon are both fruit, contrasting highlights how the subjects or items differ from each other, e.g. a watermelon is around 10 times larger than a banana.

Any question that you are asked in education will have a variety of interesting comparisons and deductions that you can make.

Compare is the same as similarities.

Contrast is the same as differences.

This is because comparing identifies the likeness between two subjects, items, or categories, while contrasting recognizes disparities between them.

When you compare things, you represent them regarding their similarity, but when you contrast things, you define them in reference to their differences.

As a result, if you are asked to discuss the similarities and differences between two subjects, you can take an identical approach to if you are writing a compare and contrast essay.

In writing, the purpose of comparing and contrasting is to highlight subtle but important differences or similarities that might not be immediately obvious.

By illustrating the differences between elements in a similar category, you help heighten readers’ understanding of the subject or topic of discussion.

For instance, you might choose to compare and contrast red wine and white wine by pointing out the subtle differences. One of these differences is that red wine is best served at room temperature while white is best served chilled.

Also, comparing and contrasting helps to make abstract ideas more definite and minimizes the confusion that might exist between two related concepts.

Can Comparing and Contrasting Be Useful Outside of Academia?

Comparing enables you to see the pros and cons, allowing you to have a better understanding of the things under discussion. In an essay, this helps you demonstrate that you understand the nuances of your topic enough to draw meaningful conclusions from them.

Let's use a real-word example to see the benefits. Imagine you're contrasting two dresses you could buy. You might think:

• Dress A is purple, my favorite color, but it has a difficult zip and is practically impossible to match a jacket to.
• Dress B is more expensive but I already have a suitable pair of shoes and jacket and it is easier to move in.

You're linking the qualities of each dress to the context of the decision you're making. This is the same for your essay. Your comparison and contrast points will be in relation to the question you need to answer.

Comparing and contrasting is only a useful technique when applied to two related concepts.

To effectively compare two or more things, they must feature characteristics similar enough to warrant comparison.

In addition to this they must also feature a similarity that generates an interesting discussion. But what do I mean by “interesting” here?

Let’s look at two concepts, the Magna Carta and my third grade poetry competition entry.

They are both text, written on paper by a person so they fulfil the first requirement, they have a similarity. But this comparison clearly would not fulfil the second requirement, you would not be able to draw any interesting conclusions.

However, if we compare the Magna Carta to the Bill of Rights, you would be able to come to some very interesting conclusions concerning the history of world politics.

To write a good compare and contrast essay, it’s best to pick two or more topics that share a meaningful connection .

The aim of the essay would be to show the subtle differences or unforeseen similarities.

By highlighting the distinctions between elements in a similar category you can increase your readers’ understanding.

Alternatively, you could choose to focus on a comparison between two subjects that initially appear unrelated.

The more dissimilar they seem, the more interesting the comparison essay will turn out.

For instance, you could compare and contrast professional rugby players with marathon runners.

Can You Compare and Contrast in an Essay That Does Not Specifically Require It?

As a writer, you can employ comparing and contrasting techniques in your writing, particularly when looking for ideas you can later apply in your argument.

You can do this even when the comparison or contrast is not a requirement for the topic or argument you are presenting. Doing so could enable you to build your evaluation and develop a stronger argument.

Note that the similarities and differences you come up with might not even show up in the final draft.

While the use of compare and contrast can be neutral, you can also use it to highlight one option under discussion. When used this way, you can influence the perceived advantages of your preferred option.

As a writing style, comparing and contrasting can encompass an entire essay. However, it could also appear in some select paragraphs within the essay, where making some comparisons serves to better illustrate a point.

What Should You Do First?

Before you compare two things, always start by deciding on the reason for your comparison, then outline the criteria you will use to compare them.

Words and phrases commonly used for comparison include:

In writing, these words and phrases are called transitions . They help readers to understand or make the connection between sentences, paragraphs, and ideas.

Without transition words writing can feel clumsy and disjointed making it difficult to read. ProWritingAid’s transition report highlights all of a documents transitions and suggests that 25% of any sentences in a piece include a transition.

Sign up for a free ProWritingAid account to use the Transitions Report.

So, how do you form all of this into a coherent essay? It's a good idea to plan first, then decide what your paragraph layout will look like.

Venn diagrams are useful tool to start generating ideas. The, for your essay, you need to choose between going idea by idea and going point by point.

Using a Venn Diagram

A Venn diagram helps you to clearly see the similarities and differences between multiple objects, things, or subjects.

The writing tool comprises two, or more, simple, overlapping circles in which you list down the things that are alike (within the overlapping area) and those that differ (outside the overlapping area).

It’s great for brainstorming ideas and for creating your essay’s outline. You could even use it in an exam setting because it is quick and simple.

Going Subject by Subject

Going subject by subject is a structural choice for your essay.

Start by saying all you have to say on the first subject, then proceed to do the same about the second subject.

Depending on the length of your essay, you can fit the points about each subject into one paragraph or have several sections per each subject, ending with a conclusion.

This method is best for short essays on simple topics. Most university-level essays will go point by point instead.

Going Point by Point

Going point by point, or alternating, is the opposite essay structure from going subject by subject. This is ideal when you want to do more direct comparing and contrasting. It entails discussing one comparison point at a time. It allows you to use a paragraph to talk about how a certain comparing/contrasting point relates to the subjects or items you are discussing.

Alternatively, if you have lots of details about the subject, you might decide to use a paragraph for each point.

An academic compare and contrast essay looks at two or more subjects, ideas, people, or objects, compares their likeness, and contrasts their differences.

It’s an informative essay that provides insights on what is similar and different between the two items.

Depending on the essay’s instructions, you can focus solely on comparing or contrasting, or a combination of the two.

• History: Compare and contrast WWI to WWII with specific reference to the causes and outcomes.
• Medicine: Compare and contrast England’s health service with America’s health service.
• Psychology: Compare and contrast the behaviorist theory with the psychodynamic theory.

So, the key takeaways to keep in mind are:

Have a basis for comparison. The two things need to have enough in common to justify a discussion about their similarities and disparities.

Don’t go back and forth when using the block method. The best way to write your essay is to begin with a paragraph discussing all the facets of the first topic. Then, move on to another paragraph and talk through all the aspects of the second subject.

You can use both alternating and blocking techniques. Combining the two approaches is also an option. You can apply the alternating method in some paragraphs, then switch and use the block method. This method will help you offer a much deeper analysis of the subjects.

Have a reason for comparing the two things. Only select the points of comparison that resonate with your purpose.

Comparing and contrasting are essential analytical skills in academic writing. When your professor issues you with such an essay, their primary goal is to teach you how to:

• Engage in critical thinking
• See and make connections between words or ideas
• Move beyond mere descriptions or summaries to developing interesting analysis
• Get a deeper understanding of the subjects or items under comparison, their key features, and their interrelationships with each other.

Ultimately, your essay should enlighten readers by providing useful information.

The purpose of a compare and contrast essay is to analyze the differences and/or the similarities of two distinct subjects. A good compare/contrast essay doesn’t only point out how the subjects are similar or different (or even both!). It uses those points to make a meaningful argument about the subjects. While it can be a little intimidating to approach this type of essay at first, with a little work and practice, you can write a great compare-and-contrast essay!

Formulating Your Argument

• You could pick two subjects that are in the same “category” but have differences that are significant in some way. For example, you could choose “homemade pizza vs. frozen grocery store pizza.”
• You could pick two subjects that don’t appear to have anything in common but that have a surprising similarity. For example, you could choose to compare bats and whales. (One is tiny and flies, and the other is huge and swims, but they both use sonar to hunt.)
• You could pick two subjects that might appear to be the same but are actually different. For example, you could choose "The Hunger Games movie vs. the book."

• For example, ask yourself: What can we learn by thinking about “The Hunger Games” and “Battle Royale” together that we would miss out on if we thought about them separately?
• It can be helpful to consider the “So what?” question when deciding whether your subjects have meaningful comparisons and contrasts to be made. If you say “The Hunger Games and Battle Royale are both similar and different,” and your friend asked you “So what?” what would your answer be? In other words, why bother putting these two things together?

• A “Venn diagram” can often be helpful when brainstorming. This set of overlapping circles can help you visualize where your subjects are similar and where they differ. In the outer edges of the circle, you write what is different; in the overlapping middle area, you write what’s similar. [2] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
• You can also just draw out a list of all of the qualities or characteristics of each subject. Once you’ve done that, start looking through the list for traits that both subjects share. Major points of difference are also good to note.

• For example, if you are comparing and contrasting cats and dogs, you might notice that both are common household pets, fairly easy to adopt, and don’t usually have many special care needs. These are points of comparison (ways they are similar).
• You might also note that cats are usually more independent than dogs, that dogs may not provoke allergies as much as cats do, and that cats don’t get as big as many dogs do. These are points of contrast (ways they are different).
• These points of contrast can often be good places to start thinking about your thesis, or argument. Do these differences make one animal a superior type of pet? Or a better pet choice for a specific living situation (e.g., an apartment, a farm, etc.)?

• Show readers why one subject is more desirable than the other. Example: "Cats are better pets than dogs because they require less maintenance, are more independent, and are more adaptable."
• Help readers make a meaningful comparison between two subjects. Example: "New York City and San Francisco are both great cities for young professionals, but they differ in terms of their job opportunities, social environment, and living conditions."
• Show readers how two subjects are similar and different. Example: "While both The Catcher in the Rye and To Kill a Mockingbird explore the themes of loss of innocence and the deep bond between siblings, To Kill a Mockingbird is more concerned with racism while The Catcher in the Rye focuses on the prejudices of class."
• In middle school and high school, the standard format for essays is often the “5-paragraph form,” with an introduction, 3 body paragraphs, and a conclusion. If your teacher recommends this form, go for it. However, you should be aware that especially in college, teachers and professors tend to want students to break out of this limited mode. Don’t get so locked into having “three main points” that you forget to fully explore your topic.

Organizing Your Essay

• Subject by subject. This organization deals with all of the points about Topic A, then all of the points of Topic B. For example, you could discuss all your points about frozen pizza (in as many paragraphs as necessary), then all your points about homemade pizza. The strength of this form is that you don’t jump back and forth as much between topics, which can help your essay read more smoothly. It can also be helpful if you are using one subject as a “lens” through which to examine the other. The major disadvantage is that the comparisons and contrasts don’t really become evident until much further into the essay, and it can end up reading like a list of “points” rather than a cohesive essay. [4] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
• Point by point. This type of organization switches back and forth between points. For example, you could first discuss the prices of frozen pizza vs. homemade pizza, then the quality of ingredients, then the convenience factor. The advantage of this form is that it’s very clear what you’re comparing and contrasting. The disadvantage is that you do switch back and forth between topics, so you need to make sure that you use transitions and signposts to lead your reader through your argument.
• Compare then contrast. This organization presents all the comparisons first, then all the contrasts. It’s a pretty common way of organizing an essay, and it can be helpful if you really want to emphasize how your subjects are different. Putting the contrasts last places the emphasis on them. However, it can be more difficult for your readers to immediately see why these two subjects are being contrasted if all the similarities are first.

• Introduction. This paragraph comes first and presents the basic information about the subjects to be compared and contrasted. It should present your thesis and the direction of your essay (i.e., what you will discuss and why your readers should care).
• Body Paragraphs. These are the meat of your essay, where you provide the details and evidence that support your claims. Each different section or body paragraph should tackle a different division of proof. It should provide and analyze evidence in order to connect those proofs to your thesis and support your thesis. Many middle-school and high-school essays may only require three body paragraphs, but use as many as is necessary to fully convey your argument.
• Acknowledgement of Competitive Arguments/Concession. This paragraph acknowledges that other counter-arguments exist, but discusses how those arguments are flawed or do not apply.
• Conclusion. This paragraph summarizes the evidence presented. It will restate the thesis, but usually in a way that offers more information or sophistication than the introduction could. Remember: your audience now has all the information you gave them about why your argument is solid. They don’t need you to just reword your original thesis. Take it to the next level!

• Introduction: state your intent to discuss the differences between camping in the woods or on the beach.
• Body Paragraph 1 (Woods): Climate/Weather
• Body Paragraph 2 (Woods): Types of Activities and Facilities
• Body Paragraph 3 (Beach): Climate/Weather
• Body Paragraph 4 (Beach): Types of Activities and Facilities

• Introduction

• Body Paragraph 1: Similarity between woods and beaches (both are places with a wide variety of things to do)
• Body Paragraph 2: First difference between woods and beaches (they have different climates)
• Body Paragraph 3: Second difference between woods and beaches (there are more easily accessible woods than beaches in most parts of the country)
• Body Paragraph 4: Emphasis on the superiority of the woods to the beach

• Topic sentence: This sentence introduces the main idea and subject of the paragraph. It can also provide a transition from the ideas in the previous paragraph.
• Body: These sentences provide concrete evidence that support the topic sentence and main idea.
• Conclusion: this sentence wraps up the ideas in the paragraph. It may also provide a link to the next paragraph’s ideas.

Putting It All Together

• If you are having trouble finding evidence to support your argument, go back to your original texts and try the brainstorming process again. It could be that your argument is evolving past where it started, which is good! You just need to go back and look for further evidence.

• For example, in a body paragraph about the quality of ingredients in frozen vs. homemade pizza, you could close with an assertion like this: “Because you actively control the quality of the ingredients in pizza you make at home, it can be healthier for you than frozen pizza. It can also let you express your imagination. Pineapple and peanut butter pizza? Go for it! Pickles and parmesan? Do it! Using your own ingredients lets you have fun with your food.” This type of comment helps your reader understand why the ability to choose your own ingredients makes homemade pizza better.

• Reading your essay aloud can also help you find problem spots. Often, when you’re writing you get so used to what you meant to say that you don’t read what you actually said.

• Avoid bias. Don't use overly negative or defamatory language to show why a subject is unfavorable; use solid evidence to prove your points instead.
• Avoid first-person pronouns unless told otherwise. In some cases, your teacher may encourage you to use “I” and “you” in your essay. However, if the assignment or your teacher doesn’t mention it, stick with third-person instead, like “one may see” or “people may enjoy.” This is common practice for formal academic essays.
• Proofread! Spelling and punctuation errors happen to everyone, but not catching them can make you seem lazy. Go over your essay carefully, and ask a friend to help if you’re not confident in your own proofreading skills.

Sample Body Paragraphs

• "When one is deciding whether to go to the beach or the woods, the type of activities that each location offers are an important point to consider. At the beach, one can enjoy the water by swimming, surfing, or even building a sandcastle with a moat that will fill with water. When one is in the woods, one may be able to go fishing or swimming in a nearby lake, or one may not be near water at all. At the beach, one can keep one's kids entertained by burying them in sand or kicking around a soccer ball; if one is in the woods, one can entertain one's kids by showing them different plans or animals. Both the beach and the woods offer a variety of activities for adults and kids alike."

• "The beach has a wonderful climate, many activities, and great facilities for any visitor's everyday use. If a person goes to the beach during the right day or time of year, he or she can enjoy warm, yet refreshing water, a cool breeze, and a relatively hot climate. At the beach, one can go swimming, sunbathe, or build sandcastles. There are also great facilities at the beach, such as a changing room, umbrellas, and conveniently-located restaurants and changing facilities. The climate, activities, and facilities are important points to consider when deciding between the beach and the woods."

10.7 Comparison and Contrast

Learning objectives.

• Determine the purpose and structure of comparison and contrast in writing.
• Explain organizational methods used when comparing and contrasting.
• Understand how to write a compare-and-contrast essay.

The Purpose of Comparison and Contrast in Writing

Comparison in writing discusses elements that are similar, while contrast in writing discusses elements that are different. A compare-and-contrast essay , then, analyzes two subjects by comparing them, contrasting them, or both.

The key to a good compare-and-contrast essay is to choose two or more subjects that connect in a meaningful way. The purpose of conducting the comparison or contrast is not to state the obvious but rather to illuminate subtle differences or unexpected similarities. For example, if you wanted to focus on contrasting two subjects you would not pick apples and oranges; rather, you might choose to compare and contrast two types of oranges or two types of apples to highlight subtle differences. For example, Red Delicious apples are sweet, while Granny Smiths are tart and acidic. Drawing distinctions between elements in a similar category will increase the audience’s understanding of that category, which is the purpose of the compare-and-contrast essay.

Similarly, to focus on comparison, choose two subjects that seem at first to be unrelated. For a comparison essay, you likely would not choose two apples or two oranges because they share so many of the same properties already. Rather, you might try to compare how apples and oranges are quite similar. The more divergent the two subjects initially seem, the more interesting a comparison essay will be.

Writing at Work

Comparing and contrasting is also an evaluative tool. In order to make accurate evaluations about a given topic, you must first know the critical points of similarity and difference. Comparing and contrasting is a primary tool for many workplace assessments. You have likely compared and contrasted yourself to other colleagues. Employee advancements, pay raises, hiring, and firing are typically conducted using comparison and contrast. Comparison and contrast could be used to evaluate companies, departments, or individuals.

Brainstorm an essay that leans toward contrast. Choose one of the following three categories. Pick two examples from each. Then come up with one similarity and three differences between the examples.

• Romantic comedies
• Internet search engines
• Cell phones

Brainstorm an essay that leans toward comparison. Choose one of the following three items. Then come up with one difference and three similarities.

• Department stores and discount retail stores
• Fast food chains and fine dining restaurants
• Dogs and cats

The Structure of a Comparison and Contrast Essay

The compare-and-contrast essay starts with a thesis that clearly states the two subjects that are to be compared, contrasted, or both and the reason for doing so. The thesis could lean more toward comparing, contrasting, or both. Remember, the point of comparing and contrasting is to provide useful knowledge to the reader. Take the following thesis as an example that leans more toward contrasting.

Thesis statement: Organic vegetables may cost more than those that are conventionally grown, but when put to the test, they are definitely worth every extra penny.

Here the thesis sets up the two subjects to be compared and contrasted (organic versus conventional vegetables), and it makes a claim about the results that might prove useful to the reader.

You may organize compare-and-contrast essays in one of the following two ways:

• According to the subjects themselves, discussing one then the other
• According to individual points, discussing each subject in relation to each point

See Figure 10.1 “Comparison and Contrast Diagram” , which diagrams the ways to organize our organic versus conventional vegetables thesis.

Figure 10.1 Comparison and Contrast Diagram

The organizational structure you choose depends on the nature of the topic, your purpose, and your audience.

Given that compare-and-contrast essays analyze the relationship between two subjects, it is helpful to have some phrases on hand that will cue the reader to such analysis. See Table 10.3 “Phrases of Comparison and Contrast” for examples.

Table 10.3 Phrases of Comparison and Contrast

Create an outline for each of the items you chose in Note 10.72 “Exercise 1” and Note 10.73 “Exercise 2” . Use the point-by-point organizing strategy for one of them, and use the subject organizing strategy for the other.

Writing a Comparison and Contrast Essay

First choose whether you want to compare seemingly disparate subjects, contrast seemingly similar subjects, or compare and contrast subjects. Once you have decided on a topic, introduce it with an engaging opening paragraph. Your thesis should come at the end of the introduction, and it should establish the subjects you will compare, contrast, or both as well as state what can be learned from doing so.

The body of the essay can be organized in one of two ways: by subject or by individual points. The organizing strategy that you choose will depend on, as always, your audience and your purpose. You may also consider your particular approach to the subjects as well as the nature of the subjects themselves; some subjects might better lend themselves to one structure or the other. Make sure to use comparison and contrast phrases to cue the reader to the ways in which you are analyzing the relationship between the subjects.

After you finish analyzing the subjects, write a conclusion that summarizes the main points of the essay and reinforces your thesis. See Chapter 15 “Readings: Examples of Essays” to read a sample compare-and-contrast essay.

Many business presentations are conducted using comparison and contrast. The organizing strategies—by subject or individual points—could also be used for organizing a presentation. Keep this in mind as a way of organizing your content the next time you or a colleague have to present something at work.

Choose one of the outlines you created in Note 10.75 “Exercise 3” , and write a full compare-and-contrast essay. Be sure to include an engaging introduction, a clear thesis, well-defined and detailed paragraphs, and a fitting conclusion that ties everything together.

Key Takeaways

• A compare-and-contrast essay analyzes two subjects by either comparing them, contrasting them, or both.
• The purpose of writing a comparison or contrast essay is not to state the obvious but rather to illuminate subtle differences or unexpected similarities between two subjects.
• The thesis should clearly state the subjects that are to be compared, contrasted, or both, and it should state what is to be learned from doing so.

There are two main organizing strategies for compare-and-contrast essays.

• Organize by the subjects themselves, one then the other.
• Organize by individual points, in which you discuss each subject in relation to each point.
• Use phrases of comparison or phrases of contrast to signal to readers how exactly the two subjects are being analyzed.

How to Write a Compare and Contrast Essay

5-minute read

• 9th March 2021

In a compare and contrast essay , you look at the similarities and differences between two subjects. How do you write one, though? Key steps include:

• Pick two things to compare based on the assignment you were given.
• Brainstorm the similarities and differences between your chosen subjects.
• Choose a structure for your essay and plan how you will write it.
• Write up your comparison and use evidence to support your argument.
• Revise and proofread your essay to make sure it is perfect.

For more advice on each stage, check out our guide below.

1. Pick Two Subjects to Compare and Contrast

A compare and contrast assignment will ask you, unsurprisingly, to compare and contrast two things. In some cases, the assignment question will make this clear. For instance, if the assignment says “Compare how Mozart and Beethoven use melody,” you will have a very clear sense of what to write about!

Other times, you will have a choice of what to compare. In this case, you will want to pick two things that are similar enough to make a useful comparison.

For example, comparing Mozart and Beethoven makes sense because both are classical composers. This means there will be lots of points of comparison between them. But comparing Mozart to a Ferrari SF90 Stradale would just be confusing: one is a renowned composer and musician, the other is a high-end sports car, so they have very little in common that we could usefully compare.

At the same time, the things you pick should be different enough that you can find points of contrast. Were you asked to compare the calorific content of two types of fast food, for example, it might not make sense to compare hamburgers and cheeseburgers as they are too similar. But you could compare hamburgers and pizzas since both are forms of fast food but they differ in other respects.

As such, if you need to pick the subjects of your essay, read your assignment question carefully and try to find two things that will produce a helpful comparison.

2. Brainstorm Their Similarities and Differences

The next step is to brainstorm similarities and differences between your chosen subjects. You can do this as a simple list, but you could also use a Venn diagram .

This is a set of overlapping circles, each of which represents one subject. You can then add characteristics to each circle, with anything your subjects have in common going in the overlapping bit in the middle.

Once you’ve listed characteristics, you’ll need to pick out the similarities and differences relevant to your essay. If you were assigned a question, use this to guide your choices. Otherwise, look for features that seem surprising or interesting and plan your essay around these. The key is to pick points of comparison that help us to understand each thing better, or where the similarities and differences show us something that we might not have expected or noticed otherwise.

3. Choose a Structure for Your Essay

As with any essay, you will want to start with a short introduction where you introduce your topic and what you will argue. Beyond this, most compare and contrast essays are structured in one of two ways. Decide which approach to take before you write your essay outline :

• Divide by subject – Cover each subject in turn, looking at the key features you’ve identified in the previous step. You can then include a final section where you highlight what comparing the subjects tell us.
• Divide by individual points – Break your essay down into a series of sections. Each section will then focus on one of the key features you’ve identified, explaining the similarities and differences between your chosen subjects.

For instance, if you were comparing two novels, you could write about each novel in turn and then compare them at the end. Alternatively, you could structure your essay so that each section covers an individual idea (e.g., one on structure, one on characters, one on language), looking at how each book uses these things.

In either case, you will want to end on a conclusion where you summarize what the comparison has shown us about the two subjects.

4. Use Supporting Evidence for Your Argument

It is important that you also back up your statements with supporting evidence. In some cases, this will simply involve pointing to the features of each subject that you’re discussing (e.g., citing specific parts of the novels you’re comparing).

However, you can also do extra research to back up your arguments. Were you comparing two countries’ economic performance, for example, you could use statistics from other studies or reports to show the similarities and differences.

5. Proofread Your Compare and Contrast Essay

Once you have a first draft of your compare and contrast essay, take a break. If you have time, leave it overnight. The aim is to come back to it with fresh eyes and reread it, looking for any areas you could improve. After this, you can redraft your essay to make sure your argument is clear, concise, and convincing.

It is also a good idea to have your essay proofread before submitting it. This will ensure your work is error free and help you get the marks you deserve.
