Introduction
A summary is a short version of a longer text that keeps only the main points, written in your own words. It answers one question for the reader: what does this article actually say? Everything else — examples, repetition, and side details — gets left out.
Writing a good summary is a skill students use in every subject, and it follows the same five steps regardless of the topic. In this guide, you will learn those steps, see a worked example with a real before-and-after, and find the mistakes that quietly cost marks.
The 5 Steps to Summarize Any Article
Step 1: Read the Article Twice
Read once for the general idea, without taking notes. Just absorb the topic, the author's main argument, and the overall direction. Then read a second time slowly, marking the thesis statement, the main supporting points, and any key evidence.
Two passes feel slower, but they prevent the most common summary failure: writing about the first half of the article because you never properly understood the second half.
Step 2: Find the Thesis and Main Points
The thesis is the author's central claim, usually stated near the start or the end of the introduction. The main points are the handful of ideas that support it — often one per section or paragraph group.
Write each main point down as a single short sentence in your own words. If you cannot state a point in one sentence, you probably have not understood it yet, and that is worth knowing before you draft.
Step 3: Build a Reverse Outline
A reverse outline is a simple map of what the author already wrote. List the thesis first, then each main point in the order it appears, with one line of supporting evidence each.
This outline becomes the skeleton of your summary. It stops you from drifting into details, because anything that is not on the outline does not belong in the summary.
Step 4: Draft in Your Own Words
Write the summary from your outline, not from the article. Close the article or look away from the screen, and explain what you remember the way you would explain it to a classmate.
This is the rule that trips people up most. Rearranging an author's sentence and swapping a few words is not paraphrasing — it is too close to the original. True paraphrasing changes both the words and the sentence structure.
Use present tense when referring to what the author argues, and refer to the author by name or as "the author" so it stays clear the ideas are theirs, not yours.
Step 5: Revise and Check
Read your summary against the original and ask three questions. Does it cover every main point? Does it add any opinion of yours? Does it change any claim, even slightly?
Also check the length. A useful benchmark is about one third of the original article. A summary nearly as long as the source saves no time, while one far shorter usually drops points you needed.
A Worked Example
Original paragraph (written for this guide):
Over the past decade, many city libraries have extended their evening hours and added quiet study rooms, coworking desks, and free tutoring sessions. Librarians report that the change was driven less by book lending, which has stayed flat, and more by demand from students and remote workers who need a free, quiet place with reliable internet. Early surveys from three cities suggest evening visitors now outnumber daytime visitors on weekdays, although the libraries caution that the data covers only the first year of the new hours.
Summary (two sentences):
City libraries have extended evening hours and added study and coworking spaces in response to demand from students and remote workers, rather than changes in book lending. Early surveys suggest evening visitors now outnumber daytime visitors on weekdays, though the data covers only the first year.
Why it works: The summary keeps the main claim (libraries changed for study demand, not lending), the key evidence (evening visitors outnumbering daytime ones), and the important qualification (first-year data only). It drops the specific list of rooms and services, which are details, not main points.
How Long Should a Summary Be?
It depends on the original, but one third of the source length is a widely used benchmark. A 3,000-word article becomes roughly a 1,000-word summary; a 900-word article becomes about 300 words.
For short assignments, a single paragraph often works: a topic sentence naming the title, author, and thesis, followed by one sentence per main point. For longer articles, use one paragraph per main point, each opening with its own topic sentence.
The real test is not the word count. It is whether someone who reads only your summary understands the article's argument without opening the original.
Mistakes to Avoid
Copying sentences. Lifting the author's sentences, even with small word changes, is not summarizing. Write from your outline and your memory, then check back only for accuracy.
Adding your opinion. A summary reports what the author says, not what you think about it. Save your own analysis for a separate response or review.
Including examples and details. Dates, statistics, and anecdotes usually support a main point rather than being one. Leave them out unless a detail is itself central to the argument.
Changing the meaning. Small wording shifts can upgrade a cautious claim into a confident one. If the author says something "may help", your summary must not say it "will help".
Skipping the citation. Name the author and title in your first sentence, and follow your course's citation style. A summary without attribution reads as if the ideas were yours.
Frequently Asked Questions
What is the difference between a summary and a paraphrase?
A paraphrase restates a specific passage in your own words, keeping roughly the same length and detail. A summary condenses a whole text, keeping only the main points at a fraction of the original length.
Do I need to cite sources in a summary?
Yes. Name the author and the title in your opening sentence, and follow your course's citation format for any references. Attribution is what separates a summary from plagiarism.
Can a summary include quotes?
Short quotes are fine when a phrase is memorable or exact wording matters, but a summary should be mostly your own words. If more than a small fraction is quoted, you are copying, not summarizing.
How do I summarize an article I disagree with?
Report the author's argument faithfully, even when you disagree. Your opinion belongs in a separate response, not inside the summary. A summary that distorts the original to make it easier to attack is not a summary.
Can an AI tool summarize an article for me?
Yes, and it is a useful first pass for long texts. Paste the article and get the main points in a minute, then check the result against the original before relying on it. For anything you will quote or submit, read the original yourself as well.
Conclusion
Writing a summary comes down to five habits: read twice, find the thesis and main points, outline them, draft in your own words, and revise against the original. Practice them on short articles first, and longer ones will feel manageable.
