Sentence Counter

A sentence ends at a full stop, a question mark or an exclamation mark, but not every full stop ends a sentence. This page uses your browser's built-in sentence rules (the Unicode text segmentation standard, in the page's language) and then fixes the cases those rules get wrong: titles and abbreviations such as Mr., Dr., e.g. and i.e., initials like J. K., and list numbers like 1. at the start of a line. Decimals such as 3.5 never split a sentence.

So "Dr. Lee paid $3.50 for it. Then she left." counts as two sentences, not three. A line on its own, such as a heading or a list item, counts as a sentence even without a full stop, because a line break ends a sentence in the standard rules.

Built-in sentence rules (Intl.Segmenter) are in Chrome and Edge since version 87, Safari since 14.1 and Firefox since 125, according to MDN. In an older browser the page uses its own rules of the same kind, and the note under the counts says which rules were used. No counter is perfect: an abbreviation at the very end of a sentence, such as etc., can be read either way.

The tool counts paragraphs too. A paragraph is a line that contains at least one letter or digit, so a blank line between paragraphs and a single line break both start a new one, and lines with only symbols or spaces are not counted.

If you paste an email that was wrapped at a fixed width, each wrapped line counts as a paragraph (and ends a sentence); join the lines first for an exact count.

Every sentence over 25 words is listed with its word count, and the longest is quoted. The threshold is this page's choice, a point where a sentence is worth reading again, not a rule: a long sentence can be clear, and a page of short ones can feel choppy.

Short sentences matter most where the reader is busy: a sales email read on a phone, a follow-up after a call, a script you will read out loud. Split a long sentence where it changes subject, or turn a list buried in it into bullets.

Characters are counted as a reader sees them, so an accented letter or an emoji counts once; the second figure leaves out spaces, tabs and line breaks. Words are counted the same way as on the Reading Time Calculator: runs of characters between spaces that contain a letter or digit, so a lone dash is not a word and 3.5 is one.

Limits come in different units. Essays and forms often give a word or sentence limit; social posts and meta descriptions give a character limit. Check the unit before you trim.
