Readability score checker
Paste a text to get a readability score that estimates how easy it is to read, based on sentence and word length.
How it works
A text packed with long sentences and complex words is harder to read, which can discourage visitors to a web page or blog post. This score, inspired by the Flesch index, estimates how easy a text is to read from the average sentence length and the number of syllables per word.
What does a low score like "Difficult" or "Very difficult" mean?
A low score indicates long sentences and complex words, typical of academic or technical writing. For general-audience web content, aiming for an "Easy" or "Medium" level generally improves engagement and reading time.
How can I improve a low readability score?
Shorten long sentences by splitting them into several shorter ones, prefer simple, common words over complex terms, and avoid overly nested grammatical constructions. These adjustments usually raise the score noticeably.
