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.

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.

Examples of College Level Compare and Contrast Essay Questions

Here are eleven examples of compare and contrast essay questions that you might encounter at university:

Archaeology: Compare and contrast the skulls of homo habilis, homo erectus, and homo sapiens.
Art: Compare and contrast the working styles of any two Neoclassic artists.
Astrophysics: Compare and contrast the chemical composition of Venus and Neptune.
Biology: Compare and contrast the theories of Lamarck and Darwin.
Business: Compare and contrast 2 or more business models within the agricultural industry.
Creative writing: Compare and contrast free indirect discourse with epistolary styles.
English Literature: Compare and contrast William Wordsworth with Robert Browning.
Geography: Compare and contrast the benefit of solar panels with the benefit of wind turbines.
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.

The benefits of comparing and contrasting

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

Published September 27, 2020. Updated May 4, 2022.

Compare and Contrast Essay Definition

A compare and contrast essay discusses similarities and differences between two subjects. The discussion shows the writer’s deep understanding of both subjects.

Overview of a Compare and Contrast Essay

Choose what two subjects to compare and contrast.
Brainstorm similarities and differences between the two subjects.
Develop a thesis statement and write an introduction.
Write an analysis, using the block method or the point-by-point method.
Write a conclusion.

This page will cover the following points:

Key Takeaways

What is a compare and contrast essay, step 1: choose what to compare and contrast, step 2: brainstorm similarities and differences, step 3: write an introduction and a thesis, step 4: use block method or point-to-point, step 5: write a conclusion.

Why Do Teachers Assign Compare and Contrast Essays?
A compare and contrast essay discusses the similarities and differences between two subjects to show a deep understanding of both.
Pick subjects and points that are relevant to your class .
Use your essay’s thesis statement to show the reader why the similarities and differences are important.
Choose whether you’d like to focus on one subject at a time ( block method ) or move back and forth between subjects ( point-to-point method ).
A compare and contrast essay outline includes a full thesis statement and uses appropriate structure ( block method or point-to-point ).
A thesis statement is the foundation of an essay, listing your paper’s main comparisons and explaining why they’re important.
With block structure , you dedicate each body paragraph to one of your two subjects.
With point-to-point , you dedicate each body paragraph to one of your main points about both subjects.

A compare and contrast essay discusses the similarities and differences between two subjects. This shows a deep understanding of both subjects.

Sometimes, instructors ask students to weigh the positives and negatives of both subjects, choose which subject is better, and defend their position. Read the essay prompt carefully!

Worried about your writing? Submit your paper for a Chegg Writing essay check , or for an Expert Check proofreading . Both can help you find and fix potential writing issues.

In some classes, your instructor will tell you which two subjects to focus on. They’ll usually pick topics discussed in lectures.

For example, in an American literature course, your instructor may ask you to compare and contrast two writers like Allen Ginsberg and Jack Kerouac. Both were part of the same literary movement (the Beat Generation) but still had unique styles and priorities.

Your instructor may let you choose your subjects. Pick two people, things, or ideas discussed in class with clear differences but something in common, too.

Let’s say, for example, your class is talking about pizza (what a great class, right?). You’ll want to choose two subjects in that category that are comparable, such as New York-style pizza and Chicago deep-dish pizza. Both are types of pizza, and they both mean a lot to certain American cities.

You can also find ways to contrast these two pizzas. They both have a distinct shape and are eaten differently (try eating deep-dish pizza with your hands!).

Although your class probably isn’t talking about pizza, the point here is to pick two subjects that:

Your instructor or textbook discussed.
You feel confident about and which have several important similarities and differences.

But how will you know if any given similarity or difference is important ? In the next section, you’ll brainstorm your essay’s main points and pick the ones that are most appropriate for your class.

By now, you’ve chosen (or were told) your two subjects. Next, it’s time to think about what differences and similarities your paper should focus on.

Since this brainstorming session is just for you, feel free to use whichever method you prefer. Some people like to use Venn diagrams to organize their thoughts. Others prefer a T-chart or just jotting ideas down.

Not all compare and contrast points are made equal. Think about what your instructor has talked about in class so far. Then, decide which points would sound the most appropriate for your course.

This is also a good time to revisit the prompt. Your instructor may have already hinted at what they’d like you to discuss in the instructions.

Here’s an example of a brainstorming session about New York- and Chicago-style pizza. Let’s figure out which of these compare and contrast points would be best for the paper:

After brainstorming, you have four very different points for your pizza paper. Each could be helpful, depending on the class.

If the class is about local history, then the last point, “many restaurants nearby make it,” will be useful. If not, then that point is likely the least relevant.

Meanwhile, a class about United States history will care deeply about how these different foods helped shape the identity of Chicago and New York City, respectively (point #3).

Points #1 and #2 talk about the size and shape of the pizza. These would be great choices for a home economics class, where the preparation and presentation of the dish are important.

Whichever points you choose for your compare and contrast essay, make sure they make sense and seem relevant to your class. Never throw in an extra point just to reach the word count for the paper. Your instructor will be able to tell!

Once you have three or four relevant points for your compare and contrast essay, it’s time to write the thesis statement. This will tell your instructor why these similarities and differences are important and worth talking about in an essay.

The introduction is where you’ll tell your audience what your two subjects are. You’ll also discuss the main ways you plan to compare and contrast them.

One of the most important parts of your introduction (and the whole paper) is your thesis statement. The thesis is the main argument of your essay.

Why should someone care about the similarities and differences between these two subjects? That’s the question your thesis statement should answer.

Let’s think, for example, about the New York- and Chicago-style pizza essay. Why should your instructor care about comparing and contrasting these two pizza types?

Here’s an example thesis statement for that paper:

Both New York-style and Chicago deep-dish pizza are important to the identities of their respective cities. However, the fast, portable nature of by-the-slice New York-style pizza makes it easier for the average New Yorker to eat frequently than does the deep-dish pizza for Chicago residents.

This thesis statement not only points out differences and similarities between the pizzas but also begins to say why those differences matter. Remember that the rest of your paper should support the points made in your thesis statement and address important questions.

For example, in the pizza-paper thesis, common questions might include:

What makes New York-style pizza more portable? In what ways are these pizzas important to each city’s identity?

Now, you have a compelling thesis statement for your paper ready to go. Next, you’ll spend some time thinking about how you want to present the similarities and differences between your two subjects.

Would you like to talk about one subject at a time? Or would you prefer to switch between the two to better highlight their differences?

In the next section, you’ll learn the pros and cons of both of these styles. Then, you’ll decide which one is right for your paper.

Here’s what a well-outlined introduction looks like:

– Begin with a lighthearted discussion about the centuries-long debate over cats and dogs.

– Thesis statement: Cats and dogs have varying activity levels, maintenance needs, and ways of showing affection, which potential owners should keep in mind before deciding between the two.

There are many ways to format your compare and contrast paper. But to keep things simple, let’s focus on the two most popular strategies.

With the block method , you make all your points about subject #1 before switching to subject #2. You may dedicate one or even two full paragraphs to the first subject before comparing it with the second one.

Here’s an example outline for a block method essay:

Paragraph 1: Introduction

P2: Subject #1

P3: Subject #1 (continued)

P4: Subject #2

P5: Subject #2 (continued)

P6: Conclusion

There are pros and cons to each method. The main benefit of the block method is that it is easy to keep your paper organized. Because you’re only discussing one subject at a time, your instructor can easily tell what you’re talking about.

There are still cons to this structure, though. For example, it will be harder for your audience to remember the points you made about subject #1 when you finally get to subject #2.

If you want to more closely compare and contrast your two subjects, you’ll want to use the point-to-point approach.

With point-to-point, you’ll dedicate each of your body paragraphs to a similarity or difference between the two subjects. You’ll compare and contrast both subjects in each body paragraph.

Let’s take a look at an outline organized for the point-to-point method:

P2: Similarity #1

P3: Similarity #2

P4: Difference #1

P5: Difference #2

The main benefit of point-to-point is that the similarities and differences between your two subjects will be more clear. After all, you’re going back and forth between the two at all times.

Because you are switching so often, though, you’ll want to write very clearly. Be sure to use plenty of transition words, which you’ll learn more about in the next section. Otherwise, your instructor may lose track of what you’re discussing.

Both of these methods will work with most compare and contrast essays. You’ll have to decide for yourself if you feel your subjects would be better discussed one at a time (block method) or back and forth (point-to-point).

Template on block structure and point-to-point examples

Transition words for a compare and contrast essay.

In a compare and contrast essay, you’ll be discussing at least two different subjects throughout the paper. That’s why it’s helpful to use transition words. These words will let your audience know when you’re moving on to a new topic or directly contrasting two ideas.

Here are some useful transition words for compare and contrast essays:

in contrast

As you can guess, some of these words (ex: “similarly” and “likewise”) help you compare your two subjects. Here’s an example:

Pizza-by-the-slice places are an iconic image of New York City. Similarly , visitors to Chicago make it a point to find a deep-dish pizza restaurant.

Other transition words (ex: “in contrast” and “unlike”) point to an important difference. Let’s try one out:

Unlike New York-style pizza, which can be enjoyed on the go, Chicago deep-dish pizza is suited better for a traditional, sit-down restaurant.

Use these and other transition words to make your points more clear. Try using different transition words throughout your paper, such as using “similarly” once and then “likewise” the next time. That way, you can avoid monotonous sentences.

By the time you reach the conclusion of a compare and contrast paper, you’ve already done a lot of planning and writing. It’s completely understandable if you feel a bit burned out.

Like many other papers, you’ll want to use the conclusion of your compare and contrast essay to remind your instructor of your main points. But it’s also important not to copy and paste your introduction into the conclusion.

Try to find a new, eye-catching way to transition back into your main points and restate your thesis. Here’s an example for the New York- and Chicago-style pizzas:

In the season 2 episode of The Office (US), “Valentine’s Day,” Michael Scott visits downtown New York City and immediately runs into a Sbarro’s restaurant for a “New York slice.” The scene is a joke about Michael’s naïveté. But it also points to how second nature New York-style pizza is for experiencing the area. Both New York-style and Chicago deep-dish pizza hold a special place in their city’s identities…

As always, make sure whatever you write is appropriate for your class. With a topic as light-hearted as pizza, a quick The Office reference fits right in. But in other essays, a pop culture reference would be distracting.

Here’s an example of an outline for a conclusion:

– Talk about famous cats and dogs in pop culture and their personalities, like Chloe and Max from The Secret Life of Pets .

– Restate thesis: From the palaces of Ancient Egypt to the condos of modern-day New York City, both cats and dogs have long been revered for their companionship. Potential owners should consider cats and dogs’ varying activity levels, grooming needs, and ways of showing affection before deciding which pet is right for them.

Use your conclusion to reinforce the points made throughout the paper. Adding anecdotes like the one above can make your paper stand out and keep the attention of your instructor. It’s also a way to let them know that you took the assignment seriously from the beginning to the very end.

Example Compare and Contrast Essay on J azz vs. Rock

Before you turn in that paper, don’t forget to cite your sources in APA format , MLA format , or a style of your choice.

Why Do Teachers assign Compare and Contrast Essays?

In many cases, your instructor assigns compare and contrast papers to test your comprehension of two subjects, as well as to see how well you understand authors, historical periods, or other concepts discussed in class.

Planning and writing these essays can be intimidating at first. In this guide, though, you’ll find helpful tips, from the first brainstorming session all the way to wrapping up the conclusion.
