Writing a good summary means distilling someone else’s article down to its core points, in your own words, while keeping the original meaning intact. A standard guideline is to aim for roughly one third the length of the original piece. Whether you’re summarizing for a class assignment, a work presentation, or your own notes, the process follows the same basic stages: read actively, identify the structure, then draft a condensed version that captures what matters most.
Read the Article More Than Once
Jumping straight into writing is the fastest way to produce a weak summary. Instead, plan for at least two passes through the article. On your first read, get the general idea without taking notes. Just absorb the topic, the author’s main argument or finding, and the overall direction of the piece.
On your second read, slow down and start marking things up. Highlight or underline the thesis statement (the author’s central claim or finding), the main supporting points, and any key evidence. Pay attention to topic sentences at the start of each paragraph, since those often signal the paragraph’s purpose. If the article has subheadings, use them as a map of how the author organized their thinking. Jot a one-sentence note in the margin for each section or paragraph describing what it does. By the time you finish this pass, you should be able to explain the article’s argument out loud without looking at it.
Build a Reverse Outline
A reverse outline is a simple tool that helps you see the article’s skeleton before you start writing. Rather than outlining your own summary first, you outline what the original author already wrote. Here’s how:
- Pre-read strategically. Look at the abstract (if it’s an academic paper), the introduction, and the conclusion. These sections almost always state the main question and the key findings or arguments.
- Identify the thesis or central finding. Write it down in one sentence, using your own words.
- Skim subheadings and topic sentences. Note how the author organized the piece and what role each section plays in supporting the thesis.
- Summarize each paragraph’s purpose. Write a short phrase next to each paragraph describing its main idea. Something like “presents counterargument” or “describes sample size and method” is enough.
When you’re done, you’ll have a compressed map of the entire article. This outline becomes the backbone of your summary and keeps you from accidentally wandering into minor details the author only mentioned in passing.
Write the Introduction
Your summary’s opening paragraph needs to do a few things quickly: name the article and the author, state the topic, and identify the article’s main argument or finding. Think of it as answering the question, “What is this article about and what does it conclude?” A reader who only sees your introduction should walk away understanding the article’s purpose.
For example, if you’re summarizing a research study on sleep and memory, your introduction might read: “In ‘Sleep Deprivation and Working Memory,’ Dr. Jane Lee examines whether reducing sleep to four hours per night impairs short-term recall in college students. The study finds that even two consecutive nights of restricted sleep significantly lowered participants’ scores on memory tasks.” That’s the article identified, the question stated, and the finding delivered, all in two sentences.
Draft the Body Paragraphs
The body of your summary explains how the author supports their main point. What goes here depends on the type of article you’re summarizing.
For an argumentative or opinion article, your body paragraphs should walk through the author’s key arguments and the strongest evidence behind each one. You don’t have space to cover every single point. Pick the main arguments and one or two examples that illustrate each. If the author addresses counterarguments, mention that briefly too, since it’s part of their reasoning.
For a research or empirical article, the body typically covers the methods and results. Describe who participated in the study, what the researchers measured, and how they set up the experiment. Then state the results: were the findings statistically significant? Did they confirm or contradict the original hypothesis? Keep the connection between the research question, the method, and the outcome clear. Avoid overstating the importance of the results. If the authors themselves note limitations, you can mention those in a sentence.
For a news article, the structure is different because journalism front-loads the most important information. A news piece is built around the “who, what, when, where, why, and how,” with details arranged in descending order of importance. Your summary should mirror that priority: lead with the most newsworthy facts and let smaller details fall to the end or drop out entirely.
Close With Significance
End your summary with a short paragraph on why the article’s argument or findings matter. What are the implications? If it’s a research study, what does the data suggest for future work or real-world applications? If it’s an opinion piece, what broader issue does the argument connect to? This doesn’t need to be long. Two or three sentences that explain the “so what?” will round out your summary cleanly.
Use Your Own Words
This is the rule that trips people up most often. A summary must be written in your own language, not pieced together from the author’s sentences with a few words swapped out. Rearranging a sentence and replacing some adjectives is not paraphrasing. It’s too close to the original and can cross into plagiarism.
A better approach: after reading a section, close the article (or look away from the screen) and write what you remember in the way you’d explain it to someone. Then go back and check that you captured the idea accurately. If a specific phrase from the original is so precise or distinctive that no rewording would do it justice, put it in quotation marks and attribute it to the author. But keep direct quotes to a minimum. The point of a summary is to prove you understand the material, not to echo it.
Even when you paraphrase successfully, you still need to credit the original source. Mention the author and article title in your introduction, and if your assignment requires a specific citation format, include a full reference at the end.
Keep the Right Length and Scope
A common benchmark is one third the length of the original article. So if you’re summarizing a 3,000-word paper, aim for roughly 1,000 words. This ratio isn’t a hard rule for every situation (your instructor or editor may specify a length), but it’s a useful starting point when no length is given.
Write your summary in paragraph form. Don’t use subheadings, bullet points, or numbered lists unless you’ve been told otherwise. A summary reads as a continuous, condensed version of the original, not a fragmented outline.
Stick to what the author actually said. A summary is not the place for your own opinions, critiques, or outside research. If your assignment asks for a “critical summary” or a “response,” that’s a different task. A standard summary reports the author’s ideas neutrally and accurately.
Revise Before Submitting
Once you have a draft, read it with fresh eyes and ask yourself three questions. First, could someone who hasn’t read the original article understand your summary on its own? If not, you may have skipped a key point or assumed too much context. Second, did you accidentally include minor details, tangents, or examples that aren’t essential to the main argument? Cut them. Third, compare your language to the original. If any sentences are too close to the author’s phrasing, rewrite them.
Reading your summary out loud is one of the simplest ways to catch awkward phrasing, run-on sentences, and spots where the logic jumps without a clear connection. If you stumble while reading, your reader will stumble too.
