How to Write a One Paragraph Summary of a Long Article (4-Step Routine)
Make this article actionable
Send the article context into Vife Agent and turn it into a plan, checklist, or draft you can keep working on.
Quick answer
To write a one paragraph summary of a long article, work in four passes: state the author's main claim in one sentence without looking at the text, list the two or three moves that support it, delete anything that is an example rather than a reason, then rewrite the survivors as a single paragraph that opens with the claim. The finished paragraph should contain the author's argument, not your reaction to it, and should fit in roughly 100 words.
Most weak summaries fail for one of two reasons. Either they copy the opening lines of the source, which usually set up a problem rather than state a conclusion, or they produce a sentence like "This article is about urban planning" that could describe a hundred different pieces. Both are technically accurate and carry almost no information.
Turn the useful parts into next steps
Vife Agent can convert this guide into a prioritized workflow with tasks, risks, and reusable prompts.
The four-step routine
Step 1: Write the author's main claim in one sentence, without looking at the text
Close the article, tab, or PDF. From memory, write one sentence that begins with the author's position rather than the topic. The test is whether someone could disagree with your sentence. "The article discusses tree planting programs" cannot be disagreed with. "The article argues that street tree programs fail when maintenance is funded separately from planting" can be.
If you cannot produce that sentence from memory, you have not finished reading. Go back and find the paragraph where the author states what they want you to accept, usually near the end of the introduction or in the conclusion.
Step 2: List the two or three supporting moves
Reopen the article and list the reasons the author gives for that claim. Keep the list short. Two or three items is the practical ceiling for a single paragraph; if you find six, you are listing sections rather than arguments.
Write each item as a short phrase, not a sentence. This keeps you from importing the author's phrasing wholesale.
Step 3: Cut anything that is an example rather than a reason
This is the step most people skip. Go through your list and ask of each item: if I removed this, would the claim lose support, or would it just lose illustration?
- A reason explains why the claim holds. Keep it.
- An example shows the claim in one place. Cut it, unless the example is the entire evidence base.
- A number is usually an example. Cut it unless the argument depends on the size of the effect.
- A quotation is always cut. Summaries paraphrase; they do not quote.
Step 4: Rewrite as one paragraph, claim first
Turn your remaining items into a paragraph. Open with the claim sentence from Step 1, then attach the supporting moves with connectors such as "because," "the author points to," or "the argument turns on." Do not add a closing sentence that evaluates the article. Evaluation belongs in a separate response, not in a summary.
Worked example: an invented source article
The source below is invented for illustration. It is not a real article, and no real publication, author, or dataset is being described. Treat it as a stand-in that shows the mechanics of the routine.
Imagine an 800-word article titled "The Street Tree Maintenance Gap." Its structure is roughly:
- An opening scene describing a newly planted block of saplings.
- A claim that municipal tree programs are judged on planting counts rather than survival.
- A section on how planting budgets and maintenance budgets sit in different departments.
- Two examples of neighbourhoods where saplings died within three years.
- A section on volunteer watering groups and their limits.
- A conclusion arguing that planting targets should be replaced with survival targets.
The bad summary
This article is about urban tree planting. It discusses how cities plant trees and the challenges involved in keeping them healthy. The author talks about budgets, departments, and volunteers, and explains why tree planting is important for cities. Overall, the article provides an interesting look at urban forestry.
This version names the topic six times and states no claim. It also adds "interesting," which is the summarizer's opinion, not the author's.
The intermediate bullet list
- Claim: planting targets measure the wrong thing; survival should be the metric.
- Reason: planting and maintenance budgets are controlled by different departments, so no one owns survival.
- Reason: volunteer watering groups cannot cover the maintenance load at scale.
- Example (cut): the two neighbourhoods where saplings died.
- Example (cut): the opening scene on the newly planted block.
- Detail (cut): the specific number of saplings mentioned.
The final paragraph
The article argues that municipal tree programs should be measured by sapling survival rather than by planting counts. Its central reason is structural: planting budgets and maintenance budgets sit in separate departments, so no single team is accountable when young trees die. The author also notes that volunteer watering groups, while useful, cannot absorb maintenance at city scale. The recommendation that follows is that cities replace planting targets with survival targets.
That paragraph is 76 words, opens with the claim, contains two reasons, and adds nothing the author did not say. Note that the two neighbourhood examples and the opening scene are gone. They made the original article readable; they do not make the summary informative.
A copyable prompt you can adapt
If you want a first draft to react to, this prompt asks for structure rather than a finished answer. It is an example you can edit, not a tested recipe, and the output still needs your judgement.
You are helping me summarise an article I have already read.
Article text:
[paste the full text]
Do this in order:
1. State the author's main claim in one sentence, phrased so that
someone could disagree with it.
2. List the two or three reasons the author gives for that claim.
3. List separately anything that is an example, statistic, or
quotation rather than a reason.
4. Write one paragraph of under 120 words that opens with the claim
and includes only the reasons from step 2.
Do not add your own opinion. Do not quote sentences from the article.
If the article does not contain a clear claim, say so instead of
inventing one.The last instruction matters most. Summarisers tend to smooth over a source that has no argument by manufacturing one. If the article is genuinely descriptive, your summary should say that it describes a situation rather than argues a point.
When you are working with long documents rather than a single article, a workspace such as Vife's document creator can hold the source alongside your draft so you can check the claim sentence against the original without switching windows. The routine above is what produces the summary; the workspace only keeps the material in one place.
Output review checklist
Run these four checks on your paragraph before you submit it. Each one is answerable by reading your own text, with no software involved.
| Check | Pass condition | How to test it |
|---|---|---|
Claim present | The first sentence states a position the author holds | Try to write "I disagree" after it. If you cannot, it is a topic, not a claim |
No new opinion added | Every evaluative word comes from the author | Highlight adjectives and adverbs. Delete any that are yours |
No quoted sentences | The paragraph is entirely paraphrased | Search for quotation marks. There should be none |
Under 120 words | The paragraph fits the brief | Count words. If you are over, cut examples first, then the weakest reason |
A fifth check is worth adding when the summary will be read by someone who has not seen the source: read your paragraph aloud and ask whether a listener could restate the author's position. If they can only restate the topic, Step 1 was not finished.
Common mistakes
Copying the opening lines. Introductions set up tension; they rarely state the conclusion. A summary built from the first paragraph usually describes the problem the article raises and omits the answer it reaches.
Summarising section by section. This produces a paragraph that mirrors the article's structure instead of its argument. The reader learns the shape of the piece but not its point.
Keeping every number. Statistics feel authoritative, so they survive editing. Ask whether the argument collapses without the figure. Usually it does not.
Adding a verdict. "The article makes a compelling case" is your assessment. It belongs in a review, not a summary. If your assignment asks for both, keep them in separate paragraphs.
Writing in the article's vocabulary. Borrowed phrasing is the fastest route to accidental plagiarism. If a phrase feels unusually well-formed, it probably came from the source.
FAQ
How long should a one paragraph summary be?
Aim for 80 to 120 words for a typical long-form article. Under 60 words you usually lose a supporting reason; over 150 you are probably re-narrating the article. If a strict limit is set, cut examples before reasons.
What if the article has no clear argument?
Say so. A summary can legitimately read "The article surveys three approaches to X without arguing for one." That is more useful than a fabricated claim, and it is honest about what the source does.
Can I use a summarising tool to write it?
You can use one to produce a draft, but the four checks above still apply to whatever comes out. Tools tend to preserve examples and drop reasoning, which is the opposite of what a summary needs. Treat any output as a starting point you have to verify against the source.
Should the summary include the author's name and title?
If the summary stands alone, yes: name the author and the article in the first sentence. If it sits directly under a citation or in an annotated bibliography, the claim can open the paragraph instead.
How is this different from an abstract?
An abstract is written by the author and describes the whole document, including its method and scope. A summary is written by a reader and reports the argument. That is why a summary can note that a claim is weakly supported, while an abstract would not.
What if I disagree with the article?
Keep the disagreement out of the summary paragraph. Write the summary first, check it against the four criteria, then add your response underneath. Mixing the two makes it impossible for a reader to tell what the author said and what you think.
