Sentence Length Analyzer — Measure Rhythm and Flow

Great writing varies sentence length. Short sentences punch. Long sentences develop ideas. Too many of either and the writing feels mechanical. This analyzer breaks your text down sentence by sentence so you can see whether your rhythm works.

Target averages

Journalism and marketing — 12–18 words per sentence
Blogs and general nonfiction — 15–20 words
Academic prose — 20–25 words
Legal writing — 25–30 words (but shorter is still better)

Any sentence over 30 words is flagged. These aren't automatically wrong — they can be deliberate — but they're often candidates for breaking in two. Pair this with the readability checker to see how sentence length affects grade level.
