Readability Checker
Paste a text to get a readability score matched to its language and to find the sentences that run too long.
Privacy and cost
This tool runs in your browser. What you type or paste is not sent to our servers and it costs nothing to use.
How it works
- Paste your text (ideally 100 words or more) and choose its language.
- The tool counts sentences, words and syllables (estimated by a heuristic) and applies the formula for that language.
- You get a 0-100 score, a reading level and a list of sentences over 25 words.
Example
An English text of 65 words and 9 sentences (7.2 words per sentence, 1.17 syllables per word) scores 100 on Flesch Reading Ease: "very easy". The sample is short, so the score is approximate.
What the result means
These formulas derive from Flesch: the shorter the sentences and the words, the higher the score. English uses Flesch Reading Ease, French its Kandel-Moles adaptation, Spanish the Fernández-Huerta one. For Arabic there is no validated, widely accepted formula, so no score is computed and only sentence and word statistics are shown. The formulas measure neither clarity, accuracy nor quality, and are not a Google ranking factor.
Common problems this tool helps with
- Endless sentences that discourage reading on mobile.
- Jargon and long words stacked in a text meant for the general public.
- Not knowing whether a rewrite really made a text simpler.
- Matching content to a specific audience: a manual, a help page, a blog post.
Frequently asked questions
Why is there no score for Arabic?
No validated, widely accepted readability formula exists for Arabic. Rather than invent a misleading number, the tool shows statistics: sentences, words and long sentences.
Is the score a ranking factor?
Nothing indicates that Google uses these formulas. They are a way to review your text for your readers.
Is the syllable count exact?
No, it is estimated with rules for each language (silent e, diphthongs, hiatus). Rare or foreign words may be miscounted.
What score should I aim for?
It depends on the audience. Around 60-70 is standard; technical text will score lower. Use the score to compare two versions.
