About Sentence Counter

The sentence counter helps writers, students, and editors analyze their writing structure. Understanding sentence length helps improve readability — shorter sentences are easier to read, while varying sentence length makes writing more engaging.

How to Use

  1. Paste or type your text into the input area.
  2. The tool instantly counts all sentences and shows key statistics.
  3. View the average words per sentence to gauge readability.
  4. See the longest and shortest sentences identified in your text.
  5. Scroll down to see each sentence listed individually with its word count.

How It Works

Sentences are detected by splitting text at period, exclamation mark, and question mark characters. The tool filters out fragments shorter than 2 words. Word count per sentence is calculated by splitting on whitespace.

FAQ

Sentences are split at . ! and ? characters. Very short fragments (under 2 words) are ignored to filter out abbreviations and false positives.
For readability, aim for an average of 15–20 words per sentence. Academic writing may average 20–25 words. Web content tends to work best with shorter sentences around 12–15 words.
The tool uses a simple period-detection method, so abbreviations like "Dr." may occasionally split sentences incorrectly. For most text this is not a significant issue.
