About readability scores
Readability scores estimate how easy a piece of text is to understand. The Flesch Reading Ease score runs from 0 to 100 — higher means easier to read. A score of 60 to 70 is considered plain English suitable for a general audience, while lower scores indicate more complex, academic writing.
The Flesch-Kincaid grade level translates that into a US school grade, so a grade level of 8 means an average eighth-grader could follow the text. Marketers and educators often aim for grade 7 to 9 for broad accessibility.
This tool also reports the percentage of complex words and average syllables per word, helping you spot what makes your writing harder to read. It is free, instant, and your text stays private.
