Sentence Counter
Count sentences, average words per sentence, and longest/shortest sentence in any text.
Sentence length directly affects readability. Short, punchy sentences improve comprehension and pace, while excessively long ones lose readers. This sentence counter gives you an instant breakdown of how many sentences your text contains, plus the average, longest, and shortest sentence lengths measured in words.
The tool splits text on sentence-ending punctuation (periods, exclamation marks, question marks) and filters out empty fragments. It handles abbreviations reasonably well for general-purpose text. Everything runs entirely in your browser with no data sent to any server.

FAQ
How are sentences detected?
Sentences are split on periods, exclamation marks, and question marks. Consecutive punctuation like '...' or '?!' is treated as a single sentence boundary.
Does it handle abbreviations like 'Dr.' or 'U.S.A.'?
The counter uses simple punctuation splitting, so abbreviations with periods may be counted as extra sentences. For most prose, the count is accurate.
Is my text stored anywhere?
No. Everything runs in your browser. Your text is never sent to a server.
