Readability Checker

Readability Checker scores how easy your text is to read across six standard formulas, Flesch Reading Ease, Flesch–Kincaid, Gunning Fog, SMOG, Coleman–Liau and ARI, and reports a consensus grade, because each formula weights sentence length and word complexity differently. It also highlights the long or complex sentences dragging your clarity down and counts passive-voice constructions.

The Flesch score runs 0–100, higher being easier, and is driven by two things: average sentence length and average syllables per word. That's empowering, because it tells you exactly what to change, shorten sentences and choose simpler words and the score rises. For general web content, aiming around an 8th–9th grade level (roughly 60+) hits the sweet spot most adults read comfortably.

Clear writing isn't dumbing down. Even expert audiences absorb plain, well-structured text faster, so improving readability lifts engagement and comprehension across the board. And while Google doesn't score readability directly, clearer content keeps readers on the page and serves snippets and voice search well, an indirect SEO benefit.
