A compare and contrast essay examines two subjects on the same criteria and argues what their similarities and differences reveal. Its structure is either block (subject by subject) or point by point (criterion by criterion).
This page is a practical toolkit: structure tables, outline templates for both methods, a worked sample introduction and body paragraph on one topic, transitions and a final checklist.
The Structure of a Compare and Contrast Essay
- Introduction: context for the pairing and a comparative thesis.
- Body: three or four criteria, organized by block or point by point.
- Conclusion: your overall judgment and why the comparison matters.
Point by point suits most university essays because the comparison stays visible in every paragraph.
Comparison with a Point
The weakest comparison essays describe subject A, describe subject B and list a few "both" and "but" statements. The strongest use the comparison to show something you could not see by looking at either subject alone.
Before you plan, finish this sentence: "Comparing these two shows that..." Whatever completes it is the core of your thesis.
Structure at a Glance
| Part | Block method | Point-by-point method |
|---|---|---|
| Introduction | Context and thesis | Context and thesis |
| Body part 1 | Subject A on all criteria | Criterion 1: A and B |
| Body part 2 | Subject B on all criteria, linked back to A | Criterion 2: A and B |
| Body part 3 | Optional synthesis paragraph | Criterion 3: A and B |
| Conclusion | Judgment and significance | Judgment and significance |
The block method is easier to plan; point by point is easier to read as a genuine comparison. In the block method, the second half must refer back to the first constantly.
Outline Templates
Point-by-point outline: online versus in-person university teaching
Introduction: the shift to blended learning; thesis.
Criterion 1, flexibility: online allows study around work and caring; in-person fixes time and place.
Criterion 2, engagement: in-person makes spontaneous discussion easier; online depends on course design.
Criterion 3, support: in-person offers informal help; online needs structured contact points.
Conclusion: the better model depends on the student, so universities should design blends rather than choose one.
Block outline: two poems on loss
Introduction: both poems respond to grief; thesis.
Poem A: form, imagery, tone.
Poem B: form, imagery, tone, each compared directly with poem A.
Conclusion: what the contrast in form shows about two ways of grieving.
How to Write It Step by Step
- Read the prompt and check whether it asks you to compare, contrast or both.
- Choose or confirm the subjects and the context that links them.
- Pick three or four criteria that matter for that context.
- Fill a comparison table with evidence for each subject on each criterion.
- Write your thesis from the strongest pattern in the table.
- Choose block or point by point and outline the body.
- Draft the body first, then the introduction and conclusion.
- Revise for balance and check every paragraph ends with a judgment.
Sample Introduction
Over the past decade, many universities have moved from purely in-person teaching towards blended models that combine online and campus study. Debates about the shift often treat the two formats as rivals, with one assumed to be better than the other. Comparing them on flexibility, engagement and support suggests a different conclusion: online teaching serves students with work or caring responsibilities better, while in-person teaching better supports discussion and informal help, so universities should design deliberate blends rather than choose one format.
The thesis names the criteria, takes a position and goes beyond "they have similarities and differences".
Sample Point-by-Point Body Paragraph
The formats differ most clearly in how students receive support. On campus, help often happens informally: a question after a seminar or a conversation in the library can resolve a problem in minutes. Online students lose these chance encounters, so support must be designed in through scheduled office hours, discussion boards and quick response times. Where that structure exists, online students can be as well supported as campus students; where it does not, they are more likely to fall behind unnoticed. Support, then, depends less on the format itself than on whether a course replaces informal contact with deliberate contact.
Notice the pattern: topic sentence naming the criterion, subject A, subject B with a contrast word, then a judgment linked to the thesis.
Transitions That Carry the Comparison
| To show | Use |
|---|---|
| Similarity | Similarly, likewise, in the same way, both, equally |
| Difference | By contrast, whereas, however, unlike, on the other hand |
| Concession | Although, while, even though, admittedly |
| Judgment | Overall, taken together, this suggests, ultimately |
Use a transition only where it shows a real relationship. "Similarly" should introduce something genuinely similar.
Final Checklist
- The two subjects share a clear basis for comparison.
- The thesis states what the comparison reveals.
- Both subjects are discussed on the same criteria.
- Each subject gets roughly equal depth.
- Every body paragraph ends with a judgment, not just a description.
- Transitions make similarities and differences explicit.
- The conclusion gives an overall judgment and its significance.
- Sources are cited in your required style.

Frequently Asked Questions
Point by point suits most university essays because it keeps the comparison visible. Block works well for short essays.
A short essay often has five: introduction, three body paragraphs and a conclusion. Longer essays add paragraphs per criterion.
Yes. A thesis that judges one subject stronger on certain criteria is often more interesting than a neutral one.
Usually yes, unless the prompt asks for only one. Focus on whichever reveals more about your subjects.
Restate your judgment in new words, show how the criteria support it and explain why the comparison matters.
At university level, usually yes. Use sources to support claims about each subject and cite them in your required style.
Follow your word count. At university, most run 1,000 to 2,500 words, with the body taking about 80 percent.
