About this tool

The Flesch Reading Ease formula scores text from 0 (very difficult) to 100 (very easy): 206.835 − 1.015 × (words/sentence) − 84.6 × (syllables/word). Most web content should score 60–70 (plain English, ~8th grade). Shorter sentences and simpler words raise the score — which correlates with better engagement and rankings.

FAQ

What score should I aim for?
60–70 suits general audiences; 70+ is very easy. Legal/academic text scores lower by nature.
How are syllables counted?
By a standard vowel-group heuristic — accurate enough for scoring trends, not dictionary-perfect.
How do I improve my score?
Split long sentences, swap complex words for simple ones, cut filler phrases.
