Sentence Counter
Count sentences, words, paragraphs, and characters in any text.
Why count sentences?
Sentence length is a key factor in writing quality and readability. Short sentences (8–14 words) are easy to parse. Long sentences (25+ words) can be harder to follow. A mix of lengths keeps readers engaged. Most readability formulas use average sentence length as a core input.
Frequently asked questions
How does the tool detect sentences?
Sentences are split on periods, exclamation marks, and question marks followed by a space and an uppercase letter. Abbreviations and decimal numbers may occasionally cause miscounts.
What is a good average sentence length?
For general writing, 15–20 words per sentence is a common target. Journalism and web content often aim for 12–15. Academic writing averages 25–30 but sacrifices accessibility.
