How to Write an Essay Outline: Formats, Templates and a Worked Example

To write an essay outline, start with your thesis statement, list the main points that prove it, put each point in a logical order, and add the evidence or example you will use under each one. Choose a topic outline (short phrases) or a sentence outline (full sentences). Use Roman numerals and letters to show hierarchy, then turn each entry into a paragraph.

The short answer

An essay outline is a skeleton of your essay: your thesis at the top, your main points in order beneath it, and the evidence or example for each point under that. To write one, follow five steps: settle on a working thesis, brainstorm the points that support it, group and order them, add evidence under each point, and check that every entry serves the thesis. A good outline takes ten to twenty minutes and saves far more than that when you draft.

You do not need to follow one official format. Teachers differ, and some assignments ask for a specific one, so check your brief. The templates below cover the formats most often requested in schools and universities in the US, UK, Canada, Australia and India.

Why outline at all?

• It exposes weak arguments early. If you cannot find a second point, you will find out before you have written 600 words.
• It fixes the order. Readers follow an essay more easily when each paragraph builds on the last.
• It keeps you on topic. Every paragraph must connect to the thesis. If an entry does not, cut it or change the thesis.
• It makes drafting faster. Each outline entry becomes the topic sentence of a paragraph.

Outlines are also expected in some courses as a graded step. Even if yours is not, five minutes of structure is usually worth it for any essay over a page.

Topic outline vs sentence outline

There are two main kinds, and the difference is how you word each entry.

The same entry both ways (essay arguing that schools should start later):

• Topic: Sleep research and teenagers
• Sentence: Teenagers' sleep patterns shift later in adolescence, so early start times leave many students short of sleep.

If an entry is hard to write as a sentence, that usually means the point is not yet clear. Many writers start with a topic outline and upgrade the key entries to sentences.

The alphanumeric format

The conventional layout uses alternating numbers and letters to show levels of detail:

• I. Roman numerals for the main sections (introduction, each body section, conclusion)
• A. Capital letters for main points inside a section
• 1. Arabic numbers for evidence, examples or details
• a. Lowercase letters for finer detail

Two rules keep it tidy. First, every level needs at least two entries: if you have an "A", you need a "B", otherwise fold it into the line above. Second, entries at the same level should be parallel in form, for example all noun phrases or all full sentences.

Step by step: build an outline

1. Write a working thesis. One sentence stating your position or purpose. It can change later. See how to write a thesis statement.
2. Brainstorm. List every point, example and piece of evidence you can think of, without sorting.
3. Group. Circle items that belong together. Each group is a likely body paragraph.
4. Order. Choose a logic: strongest point last, chronological, cause then effect, or most familiar to least familiar. Put the strongest or most surprising material where the reader will remember it.
5. Add evidence. Under each point, note the source, example, statistic or quotation you will use. Mark anything you still need to look up, rather than filling in details from memory.
6. Test it. Read only the main points in order. Do they prove the thesis? Is anything repeated or missing?

Argumentative essay

• I. Introduction
• A. Hook and context on [issue]
• B. Thesis: [your position and the main reasons]

Expository essay

• I. Introduction: topic, why it matters, thesis stating what you will explain
• II. Aspect or step 1: definition or explanation, example
• III. Aspect or step 2: explanation, example
• IV. Aspect or step 3: explanation, example
• V. Conclusion: summary of the explanation, wider significance

Expository essays inform rather than argue, so the thesis states what the essay will explain, not a contested opinion. See how to write an expository essay.

Compare and contrast essay

Choose one of two structures.

Block (subject by subject)

• I. Introduction and thesis (what the comparison reveals)
• II. Subject A: point 1, point 2, point 3
• III. Subject B: the same points, in the same order
• IV. Conclusion

Point by point

• I. Introduction and thesis
• II. Point 1: A, then B
• III. Point 2: A, then B
• IV. Point 3: A, then B
• V. Conclusion

Block suits short essays with few points. Point by point suits longer essays, because the reader sees each comparison side by side.

Narrative essay

• I. Opening: the scene or moment that starts the story, and the point you will reach
• II. Build-up: the setting, the people involved and the problem
• III. Turning point: the event that changes things
• IV. Resolution: what happened next
• V. Reflection: what you learned, tied back to the opening

Narrative outlines follow time order and put the meaning at the end. See how to write a narrative essay.

A worked example

Prompt: Should schools start later in the morning?

Working thesis: Secondary schools should start no earlier than 8:30 a.m., because it matches teenagers' sleep patterns, supports learning, and can be arranged without large costs.

Sentence outline:

• I. Introduction
• A. Hook: many students wake in the dark to catch a school bus.
• B. Thesis as above.
• II. Later starts match adolescent sleep
• A. Teenagers' body clocks shift later during adolescence. [Source needed: a paediatric or sleep-medicine body]
• B. Early starts therefore shorten sleep on school nights.
• III. Later starts can support learning
• A. Tired students struggle with attention. [Source needed]
• B. Schools that trialled later starts can be cited as examples. [Find a named trial and report its findings accurately]
• IV. Counterargument: logistics and activities
• A. Critics point to bus schedules, sports and after-school jobs.
• B. Response: staggered timetables and later fixtures can address these. [Evidence needed]
• V. Conclusion
• A. Restate the thesis in new words.
• B. Call for a trial in the reader's district.

Notice the bracketed notes. An outline is the right place to mark what you still have to research, so you do not drift into guessing at facts or statistics in the draft.

From outline to draft

• Each Roman numeral section becomes one or more paragraphs. Entry A under it is usually the topic sentence.
• Turn the evidence entries into the body of the paragraph. Introduce the source, give the evidence, then explain it in your own words. How to write a topic sentence and how to write a paragraph help here.
• Write the introduction last if it helps. Once you know where the essay went, the opening is easier to tune. See how to write an introduction.
• Link the sections. Add transition words between paragraphs.
• Allow the outline to change. If drafting shows a better order, update the outline rather than forcing the draft to match.

Rough proportions help with word budgets: for a 1,000-word essay, an introduction and conclusion of around 100 to 150 words each leave about 700 for the body. For the classic school structure, see the five-paragraph essay.

Common mistakes

• Writing a list of topics rather than a line of argument. "Social media" is a topic. "Social media shortens attention spans" is a point.
• Only one sub-point under a heading. Merge it or add a second.
• Entries that do not serve the thesis. Interesting is not enough.
• Outlining so much detail that you are writing the essay twice. Stop when each paragraph has a clear point and evidence.
• Treating the outline as fixed. Update it when your thinking changes.
• Leaving out the counterargument in an argumentative essay.

Using the Outline Generator as a starting point

The AdeptWrite Outline Generator builds an outline from a single topic in four modes: Article, Essay, Thesis and Presentation. In Essay mode it begins with a thesis statement and lays out the supporting sections. Treat its output as a draft skeleton to react to, not as a finished plan.

A sensible way to use it:

1. Enter your topic, as specific as you can make it. "Later school start times and teenage sleep" gives you more to work with than "school".
2. Read the result and delete any section that does not serve your own thesis.
3. Rewrite entries in your own terms, and add the evidence you have actually found. Items that need research are marked as such rather than filled with invented facts, so do the checking yourself.
4. Reorder to fit your argument.

It is a starting point for planning, and the argument still has to be yours. If your course restricts the use of assistance tools, follow its policy. Once the draft exists, the Grammar Checker can help with the proofreading pass. For a thesis or dissertation, the Thesis Title & Outline Generator suggests titles and chapter structure.

Summary

An outline is a short, flexible plan: a thesis, ordered points and evidence for each. Pick a topic outline for speed or a sentence outline for rigour, use the alphanumeric layout if your teacher wants it, and choose the template that matches your essay type. Mark what you still need to research, and let the outline change as your thinking does.
