What is a readability score?

A readability score estimates how easy your text is to read. The most common measures are the Flesch Reading Ease score (0-100, where higher is easier) and the Flesch-Kincaid Grade Level, which maps text to a US school grade. Both are based on sentence length and the number of syllables per word.

Paste your text above to see its scores instantly, along with word, sentence, and syllable counts, so you can judge whether the writing suits your audience.

What is a good readability score?

For a general web audience, aim for a Flesch Reading Ease of roughly 60-70, about a 7th-9th grade level. Plain, widely accessible content often scores higher; technical or academic writing scores lower.

To improve readability, shorten long sentences, prefer common words over jargon, and break dense paragraphs into smaller ones. Re-check the score after editing to confirm the change.
