Readability Checker

Readability formulas estimate how easy a text is to read, based on sentence length and word length. They do not judge whether the text is true, useful or well written, but they can flag text that is dense and hard to follow.

This tool uses the standard Flesch Reading Ease formula and its grade level formula, on the text you paste only. It shows word count, sentence count, reading ease and grade level, so you can spot long sentences and long words.

How to Use This Tool

1. Paste your text: paste a full article or a single section.
2. Click Check Readability: read the scores and the plain label.
3. Shorten long sentences: split very long sentences and replace needlessly long words.
4. Check again: paste the revised text and compare the scores.

Good Practice Tips

• Scores are a guide, not a target: forcing a score can make text sound simple but empty.
• Match your readers: a technical guide for experts can be harder to read than a general guide, and that is fine.
• Read it aloud: if a sentence is hard to say aloud, it is probably hard to read too.
• Do not chase rankings with scores: readability scores are not a ranking score, and they never replace useful content.
