To write an abstract, summarize your paper's purpose, method, main findings and conclusion in one short, self-contained paragraph, usually 150 to 300 words. It is the part of your paper most people read first, and often the only part.
This page explains what an abstract does, the difference between structured and unstructured formats, a step-by-step method, an annotated example and a checklist to use before you submit.
The Four Things Every Abstract Must Say
Every abstract answers four questions: why the study was done (purpose), how it was done (method), what was found (results) and what it means (conclusion). Add keywords if your journal or department asks for them.
Write it last, once the paper is finished, so it describes the paper you actually wrote.
What an Abstract Does
An abstract helps readers decide whether to read the full paper. Databases index it, examiners use it to get their bearings, and conference panels often select papers on the abstract alone.
That means it must stand on its own. A reader should understand it without seeing the paper: no undefined abbreviations, no references to figures and, in most disciplines, no citations.
Structured and Unstructured Abstracts
There are two main formats. Your journal, department or module guide decides which one you use.
| Format | What it looks like | Common in |
|---|---|---|
| Structured | Labeled headings such as Background, Methods, Results, Conclusions | Medicine, nursing, health sciences, many sciences |
| Unstructured | One continuous paragraph covering the same elements | Humanities, social sciences, many student papers |
| Descriptive | States what the paper covers, without findings | Some humanities papers and short reports |
| Informative | Includes the main findings and conclusions | Most research papers and dissertations |
Most student research papers need an informative abstract. If the guide does not specify, an unstructured informative abstract is the safe choice.
What Goes into Each Part
Think of the abstract as your paper in miniature, with roughly one or two sentences for each part.
| Part | What to include | Typical length |
|---|---|---|
| Background and purpose | The problem and your aim or research question | 1 to 2 sentences |
| Method | Design, participants or sources, and how data was analyzed | 1 to 2 sentences |
| Results | The main findings, with key figures if relevant | 2 to 3 sentences |
| Conclusion | What the findings mean and why they matter | 1 to 2 sentences |
How to Write an Abstract, Step by Step
- Finish the paper first. You cannot summarize what is not yet written.
- Reread your introduction and conclusion. They hold your aim and your answer.
- Write one sentence for each part: purpose, method, results and conclusion.
- Add detail where it matters most, usually the results.
- Cut everything else: background history, citations, examples and repetition.
- Check the word limit and trim with care.
- Read it as a stranger would. Does it make sense without the paper?
Use the past tense for what you did and found, and the present tense for what the findings mean.
An Annotated Example
Example unstructured abstract (about 150 words).
[Purpose] Nursing students report high stress during clinical placements, yet little is known about which coping strategies they find useful. This study explored how final-year nursing students at one university manage placement-related stress. [Method] Semi-structured interviews were conducted with 14 students and analyzed thematically. [Results] Three themes emerged: peer support as the most valued resource, the protective role of a supportive mentor, and the burden of travel and shift patterns. Students rarely used formal university support services, describing them as hard to access during placement. [Conclusion] The findings suggest that structured peer support and mentor preparation may reduce placement stress more effectively than general wellbeing services. Universities should consider embedding support within placements rather than relying on campus-based provision.
The labels show how each sentence does a job. In your final abstract, remove the labels unless your format requires headings.
Word Count and Length
Word limits vary, so always follow the one you are given. As a guide:
- Student research papers: often 150 to 250 words.
- APA 7th papers: APA suggests up to 250 words, though instructors may set their own limit.
- Dissertations and theses: often 250 to 350 words, sometimes up to a page.
- Conference abstracts: set by the conference, often 200 to 300 words.
In APA 7th, the abstract goes on its own page after the title page, with the bold, centered heading "Abstract". Student papers only need one if the instructor asks for it.
Choosing Keywords
Keywords help databases and search engines find your paper. Choose three to five terms a researcher would type when looking for work like yours.
- Use the main concepts from your research question.
- Include the population or setting if it is central.
- Avoid repeating words already in the title, where your guide allows.
In APA 7th, keywords appear on the line below the abstract, indented, with the label Keywords: in italics, followed by the terms in lowercase.
Common Abstract Mistakes
| Mistake | Fix |
|---|---|
| Writing it before the paper | Write it last, from the finished paper |
| Too much background | One sentence of context is usually enough |
| No results | State your main findings plainly |
| Including citations or figure references | Keep it self-contained |
| Claiming more than the paper shows | Match the conclusion to your actual findings |

Frequently Asked Questions
Usually 150 to 300 words. APA suggests up to 250 words, but always follow the limit your instructor, journal or conference sets.
Last. Once the paper is finished, you know exactly what it found and concluded.
Usually not. An abstract should stand alone, so most styles and journals advise against citations in it.
Past tense for what you did and found; present tense for what the findings mean and for general statements.
Only if the instructor asks. Professional papers always include one.
The abstract summarizes the whole paper, including findings. The introduction sets up the problem and question, and leads into the paper.
Yes. Key figures from your results make an abstract more informative, as long as they are explained briefly.
