How long should a paragraph be?
Most well-edited prose averages 3–5 sentences (about 75–150 words) per paragraph — but the medium changes the rule.
Paragraph length by medium
Academic writing tolerates long paragraphs because each one develops a complete claim: 100–200 words is normal. Web writing runs much shorter — screens make dense blocks hard to scan, so 40–80 words per paragraph keeps readers moving. Fiction is the most flexible: a paragraph can be a single word of dialogue or a page-long description, paced to the scene.
The consistent principle: one idea per paragraph. When the idea changes, the paragraph breaks.
Signs a paragraph should break
Watch for a topic shift mid-paragraph, a new speaker in dialogue, a change of time or place, or a sentence starting with "However" that actually pivots the argument. On screens, any paragraph past six or seven lines earns a second look — even if the logic holds, the reader's eye needs the white space.
Paragraph length by writing type
| Web articles / blogs | 40–80 words (2–4 sentences) |
| News writing | 25–50 words (1–2 sentences) |
| Essays / academic | 100–200 words (4–8 sentences) |
| Business documents | 60–120 words (3–5 sentences) |
| Fiction | no fixed rule — paced to the scene |
Can a paragraph be one sentence?
Yes. Single-sentence paragraphs are standard in journalism and effective anywhere for emphasis. In academic writing they read as underdeveloped, so use them sparingly there.
