Why Check Readability?
Our free readability checker calculates the Flesch Reading Ease score, Flesch-Kincaid Grade Level, and comprehensive text metrics to help you optimize content for your target audience. Readability directly impacts SEO performance, user engagement, time on page, and conversion rates.
The Flesch Reading Ease formula analyzes average sentence length and syllable count to produce a score from 0-100. Higher scores (60-100) indicate easier reading suitable for general audiences, while lower scores (0-50) indicate complex text requiring college-level comprehension.

How Readability Scoring Works
Our readability checker uses the Flesch Reading Ease formula: 206.835 - 1.015 × (words/sentences) - 84.6 × (syllables/words). This formula weighs average sentence length and syllable complexity to produce a 0-100 score. Shorter sentences and simpler words yield higher scores.
The Flesch-Kincaid Grade Level converts the same metrics into U.S. school grade equivalents. A grade level of 8.0 means 8th graders can understand the text, while 12.0 requires high school senior comprehension.
