How sentences are counted
This tool splits text on periods, exclamation marks, and question marks, then counts the resulting non-empty segments as sentences. It's a fast, practical approach that works well for most everyday writing.
Example
"This is great! Is it working? Yes, it is." is counted as 3 sentences, 8 words, and the exact character count shown alongside.
Common Use Cases
- Checking sentence count for readability or style guidelines.
- Estimating the complexity of a paragraph before editing it down.
- Quickly getting word and character counts alongside sentence count.
FAQs
Does it handle abbreviations correctly?
Not perfectly — this is a known limitation of splitting on punctuation. Abbreviations like "Dr.", "e.g.", or "U.S." contain a period but aren't sentence endings, so text with many abbreviations may show a slightly higher sentence count than a human reader would count. For most everyday writing without heavy abbreviation use, the count is accurate.
Does it count as I type?
Yes — sentence, word, and character counts all update live as you type or paste text.
What counts as a sentence-ending punctuation mark?
Periods, exclamation marks, and question marks are treated as sentence endings. Ellipses ("...") and repeated punctuation ("?!") are treated as a single ending, not multiple sentences.
