Readability report

Paste text above to measure sentence length, complex words, and reading ease.

The Readability Checker measures your text in your browser: words, sentences, average sentence length, reading and speaking time, sentences over 25 words, and words of three or more syllables. It combines these into an estimated reading-ease score. Syllables are estimated from spelling patterns, so the score is a guide — useful for comparing drafts, not an official grade level.

How it works

How Word Helper calculates results

Words, sentences, and paragraphs are counted in your browser — nothing is uploaded.

Syllables per word are estimated from spelling patterns (the same logic as the Syllable Counter), which makes the reading-ease score an estimate.

Sentences over 25 words are listed so you can split them.

Reading time assumes about 200 words per minute; speaking time about 130.

FAQ

Questions people ask

Is this an official readability grade?

No. The score is an estimate built on syllable and sentence-length approximations. It is consistent enough to compare your own drafts, but it is not an official grade-level measurement.

What counts as a long sentence?

This tool flags sentences over 25 words. That is a guide, not a rule — a well-structured 30-word sentence can be perfectly clear, but most drafts read better when very long sentences are split.

Is my text stored or sent anywhere?

No. All counting runs in your browser and your text never leaves your device.
