Readability Checker

Readability formulas estimate how hard a text is to read from the length of its sentences and words. Clear, readable copy keeps visitors on the page and helps them act. This checker runs six widely used formulas at once, including the Flesch Reading Ease score used by Yoast and Microsoft Word, and shows the statistics behind them so you know what to change.

How to use Readability Checker

1. Paste at least a few full sentences (more text gives a steadier score).
2. Read the Flesch Reading Ease score and the grade levels.
3. To improve the score, shorten long sentences and replace long words with simpler ones, then check again.

When it comes in handy

• Editing blog posts and landing pages for a general audience.
• Checking that instructions, letters and forms are plain English.
• Comparing your page's readability with a competitor's.

Frequently asked questions

What is a good Flesch score?

60 to 70 is plain English that most adults read easily. Higher is easier; below 30 is academic or legal-level text.

Does readability affect Google rankings?

Not directly; Google does not use these formulas. But clear writing keeps readers engaged, which supports the results you care about.

Does it work for other languages?

The formulas were designed for English. Scores for other languages are only a rough guide.
