Text Readability Analyzer

What is the Text Readability Analyzer?

The free Text Readability Analyzer scores your text using the Flesch Reading Ease formula and shows you the associated reading level, Avg words/sentence, Avg chars/word, and estimated Reading time. A score of 60–70 is plain English; below 30 is academic/technical. Writers, educators, and content strategists use it to match content difficulty to their audience.

• → Verify that a public-facing article is accessible to a general audience (target score 60–70).
• → Check whether educational material is appropriate for a specific grade level.
• → Simplify overly technical documentation by shortening sentences and words.
• → Compare readability before and after editing to measure improvement.
• → Audit marketing copy to ensure clarity and persuasiveness.

How to Use the Text Readability Analyzer

1. 1 Paste your text into the input area labelled "Paste your text here to analyse its readability…".
2. 2 The Flesch Reading Ease score (0–100) appears prominently — higher is easier to read.
3. 3 Check the reading level label (e.g. "8th Grade", "College Level") shown next to the score.
4. 4 Review Avg words/sentence and Avg chars/word — shorter values mean simpler text.
5. 5 The Reading time stat gives you an estimated consumption duration based on 238 wpm.

Is Flesch Reading Ease accurate for non-English text?
