Sentence Counter

A sentence counter analyzes text and reports the number of sentences, average words per sentence, longest and shortest sentences, and a reading level estimate. Writers, editors, students, and content creators use it to improve clarity and meet style guidelines.

Many style guides recommend keeping sentences under 20–25 words for readability. A sentence counter helps you spot overly long sentences and balance your prose. It's also useful for academic writing where sentence structure matters.

Sentence length affects readability and engagement. Very long sentences can confuse readers; very short ones can feel choppy. A mix of short, medium, and long sentences creates natural rhythm. Technical writing often aims for 15–20 words per sentence; marketing copy may use shorter punchy sentences.

The average words-per-sentence metric gives you a quick readability check. If your average climbs above 25, consider breaking up some sentences. If it's below 10, you might be writing in fragments.

Paste or type your text into the textarea. Statistics update in real time. You'll see sentence count, total words, average words per sentence, the longest and shortest sentences (with word counts), and a reading level estimate.

Use the results to revise: shorten the longest sentence if it's a run-on, expand fragments if needed, and aim for variety. The tool runs entirely in your browser — your text never leaves your device.
