Free Sentence Counter
A sentence ends with a period, question mark, or exclamation point. The counter below detects sentence boundaries while handling common edge cases like abbreviations (Dr., Mr., etc.) and decimals (3.14). Paste your text to count sentences live.
How the Sentence Counter Works
Sentences are detected by scanning for terminal punctuation (. ! ?) followed by whitespace or end of text. The counter normalizes common abbreviations and decimal numbers so they don't trigger false positives.
Tips & Best Practices
1Keep sentences under 20 words for readability
Sentences under 20 words score in the 'easy to read' band on most readability indices. Web readers strongly prefer short sentences.
2Vary sentence length
Mix short, medium, and long sentences. Three short sentences in a row create urgency. A long sentence after them creates space.
3Read aloud to test sentence pacing
If you run out of breath, your sentence is too long. The mouth catches what the eye misses.
4Cut connectors like 'and,' 'but,' 'so'
Long compound sentences often hide two ideas. Splitting them with a period sharpens both halves.
