Ideal sentence length for readability
Research on readability consistently shows that shorter sentences are easier to read. The average sentence length (words per sentence) is a key readability metric used by tools like Hemingway App, Flesch-Kincaid, and Gunning Fog.
| Average sentence length | Readability level |
|---|---|
| Under 14 words | Easy to read (web content, journalism) |
| 14–20 words | Moderate (business writing) |
| Over 20 words | Complex (academic, legal) |
Frequently asked questions
Sentences are detected at full stops, question marks, and exclamation marks followed by a space or end of text. Common abbreviations (Mr., Dr., etc.) and decimal numbers are handled to avoid false splits.
