Readability Checker

Estimate the readability of English prose from sentence length and approximate syllable counts. This is a writing aid, not a reading test.

All free tools

Approximate only: automatic syllable counts can be wrong, and abbreviations or decimals can affect sentence counts. Short samples are unstable. The score does not check facts, grammar, meaning, accessibility or SEO. Read the text with its audience in mind.

FAQs

What score should a business website aim for?

There is no score that fits every reader. Use this estimate to compare drafts, then check meaning, layout and audience familiarity separately.

How is the estimate calculated?

Flesch Reading Ease = 206.835 - 1.015 x (words / sentences) - 84.6 x (estimated syllables / words). Syllables are estimated from English vowel groups. This is not a search-ranking score.
