Check how easy your text is to read. Get Flesch-Kincaid reading ease score, grade level, and actionable improvement tips.
A readability score estimates how easy your text is to read. Higher scores mean easier reading. Our checker uses the Flesch-Kincaid formula — the most widely used readability measure in content writing, SEO tools and word processors.
Flesch Reading Ease = 206.835 − 1.015 × (words ÷ sentences) − 84.6 × (syllables ÷ words). Two factors drive the score: sentence length and syllables per word.
90–100: Very Easy (5th grade). 70–90: Easy (6th grade). 60–70: Standard (7–8th grade). 50–60: Fairly Difficult. 30–50: Difficult (college). 0–30: Very Difficult (academic).
The Flesch-Kincaid Grade Level converts the score to a US school grade. A score of “Grade 8” means a typical 8th-grade student can understand the text. Most web content targets Grade 7–9.
Shorten your sentences — aim for 15–20 words average. Use shorter words where meaning is equal. Break long paragraphs into 2–3 sentences. Replace passive voice with active voice.
Aim for 60–70 (Standard). Short sentences, simple words, clear structure. Most adults read comfortably at this level. Avoid jargon unless writing for specialists.
Aim for 70–80 (Easy). Short, punchy sentences work best. Remove every word that does not add meaning. Readers scroll quickly — get to the point in the first line.
Scores of 30–50 are normal and expected in scholarly writing. Do not artificially simplify complex arguments. Precision matters more than accessibility in academic contexts.
Aim for 60–70 for professional lists. Consumer audiences benefit from 70–80. Subject lines should be even simpler. Every extra word in an email costs you attention.
