Readability Checker

Higher is easier to read. Most general-audience web copy aims for 60–70 (plain English, roughly an 8th–9th-grade reading level). Scores of 30–50 read like difficult, academic prose, while 90+ is very simple text. There's no single 'right' number — match the score to your audience.

They use the same inputs (average sentence length and syllables per word) but answer different questions. Flesch reading ease is a 0–100 score where higher means easier. The Flesch–Kincaid grade level translates the same difficulty into a US school grade — a grade of 8.0 means an average 8th-grader should understand the text.

This tool estimates syllables with a vowel-group heuristic: it lowercases each word, counts runs of vowels, and drops a silent trailing 'e'. That's the standard approximation behind most readability scorers. It isn't a dictionary lookup, so unusual words can be off by a syllable — treat the scores as a guide rather than an exact measure.
