What is the Readability Score Checker?
Readability scores estimate how easy a text is to read. The Flesch Reading Ease score rates text from 0 (very hard) to 100 (very easy), while the Flesch-Kincaid grade level tells you the US school grade needed to understand it. Writers, teachers, marketers and SEO specialists use these scores to make content clearer for the audience they are writing for.
Paste your text and get five popular readability formulas at once — Flesch Reading Ease, Flesch-Kincaid grade, Gunning Fog, Coleman-Liau and the Automated Readability Index — together with word, sentence and syllable counts, an estimated reading time and speaking time, and a plain-English verdict.
