What is a Readability Score?
Readability scores measure how easy your text is to understand. A higher Flesch Reading Ease score (0–100) means simpler text. Grade-level formulas like Flesch-Kincaid estimate the US school grade needed to comprehend the content — a score of 8 means an 8th-grader can read it comfortably.
For general audiences, aim for a Flesch score of 60–70 and a grade level of 7–9. Technical content for professionals can tolerate higher grade levels.
