Frequently asked questions
What is the Flesch Reading Ease score?
A 0–100 score from the Flesch formula: 206.835 − 1.015 × (words per sentence) − 84.6 × (syllables per word). 90–100 is very easy, 60–70 is plain English, and below 30 is very hard.
What does the grade level mean?
The Flesch–Kincaid grade level estimates the US school grade needed to understand the text. Grade 8 means an average 13–14 year old can read it comfortably.
Is the syllable count exact?
No — syllables are estimated with a standard counting rule, so scores can be off by a point or two on unusual words. Treat the result as a guide, not a lab measurement.
What score should I aim for?
For web pages, emails and general audiences, aim for a Flesch score of 60 or above (grade 8 or lower). Technical writing for specialists can be lower.
