Reading ease is the Flesch formula: 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words). Syllables are estimated from vowel groups, so treat the score as a guide, not a measurement.

Reading the Flesch score
Higher is easier. Scores in the sixties and seventies read like plain English for a general audience; scores below fifty read like academic or legal text. Long sentences and long words both lower it, so the two fastest fixes are splitting sentences and swapping long words for short ones. Service pages, product descriptions, and emails to clients usually do well above sixty.
