What is a sentence counter?
A sentence counter counts how many sentences are in a piece of text and provides statistics about sentence length. Writers and editors use it to check readability and ensure text isn't too dense.
Readability guidelines
- 15-20 words per sentence: Ideal for web content
- 20-25 words: Acceptable for most audiences
- 25+ words: Harder to read, consider splitting
- 10 words or less: Great for punchy, direct writing

How does it detect sentences?
Sentences are detected by punctuation: periods (.), exclamation marks (!), and question marks (?). Consecutive punctuation (like '?!') counts as one sentence boundary.
