Readability Score
Check how easy your text is to read
Understanding Readability Scores
The Flesch-Kincaid Grade Level tells you what US school grade is needed to understand your text. Grade 8 or below is considered accessible to most adults.
Flesch Reading Ease scores range from 0-100. Higher is easier: 90-100 = 5th grader, 60-70 = 8th-9th grade, 30-50 = college level, 0-30 = graduate level.
For web content, aim for grade 6-8 (ease score 60-80). Shorter sentences and simpler words improve readability without sacrificing meaning.

About Readability Analysis
Readability scores quantify how easy a piece of text is to understand. Our analyzer calculates the Flesch-Kincaid Grade Level, Flesch Reading Ease, Gunning Fog Index, and Coleman-Liau Index simultaneously, giving you a comprehensive view of your content accessibility. These formulas consider sentence length, word length, and syllable count to estimate the education level needed to comfortably understand the text.
For web content, targeting a Flesch Reading Ease score of 60 to 70 (roughly 8th to 9th grade level) makes your writing accessible to the broadest possible audience. Even highly educated readers prefer content written at this level because it requires less cognitive effort. Medical communications, government forms, and consumer-facing legal documents are increasingly required to meet specific readability thresholds to ensure public accessibility.
Improving readability does not mean dumbing down your content. It means choosing shorter sentences, more common words, and clearer structures to convey the same ideas. Breaking long paragraphs into shorter ones, using active voice instead of passive, and replacing jargon with plain language all improve readability scores without sacrificing depth or accuracy.
