Is your writing easy to read? Check 5 readability scores instantly.
The Readability Checker analyses your text and scores it using the Flesch Reading Ease and Flesch-Kincaid Grade Level formulas. Find out if your writing is easy enough for your target audience.
Paste your text into the input box. Stats update live: average sentence length, average syllables per word, total word count, and the two main readability scores. The reading-ease panel translates the raw score into a band (very easy through to college graduate). Suggestions appear underneath — common issues like overly long sentences, passive voice, and complex vocabulary are flagged. Aim for the band that fits your audience: blogs and journalism for a general public, technical docs for an industry audience, plain-language summaries for accessible content.
Flesch Reading Ease is calculated as 206.835 − 1.015 × (words/sentences) − 84.6 × (syllables/words). Long sentences and multi-syllable words drag the score down. Flesch-Kincaid Grade Level uses a related formula: 0.39 × (words/sentences) + 11.8 × (syllables/words) − 15.59, mapping to a US school grade. Both depend on counting syllables, which is approximated with a vowel-cluster heuristic — accurate enough for prose but not perfect for technical jargon. The original formulas date from US Navy training-manual studies in the 1970s and remain the journalism standard.
Cut every sentence over 25 words in half. Replace "utilise" with "use", "facilitate" with "help", "in order to" with "to". Read the text aloud — anywhere you stumble is a candidate for rewriting. Use bullet lists for sequences. Rewrite passive voice ("the report was written by the team") into active ("the team wrote the report").
