How accurate is the count?

Good for ordinary prose, imperfect with abbreviations. 'Dr. Smith arrived.' counts as two because the full stop after 'Dr' looks like a sentence end. Text heavy with abbreviations or decimal numbers will read slightly high.

Does a sentence without final punctuation count?

No. A boundary requires terminal punctuation, so a last line with no full stop is not counted. Add one if you need it included.

What counts as a good average sentence length?

Around 15-20 words for general audiences. Divide your word count by the sentence count to check — consistently above 25 tends to read as dense.

Sentence Counter

Counts how many sentences a block of text contains, using terminal punctuation as the boundary. Useful when a brief specifies a number of sentences rather than words, and as a rough readability signal — a paragraph of two very long sentences usually wants breaking up.

What the Sentence Counter does

Sentence counting is genuinely ambiguous in English, so treat the number as a close estimate. Abbreviations, decimals and ellipses all contain full stops that do not end sentences.

How it works

Using the Sentence Counter

1Paste your text.
2The text is scanned for runs ending in a full stop, question mark or exclamation mark.
3Each run counts as one sentence.
4Consecutive punctuation such as '?!' counts as a single boundary.
5The total is displayed instantly.
