Readability Score Checker
Paste your text to get its Flesch Reading Ease score and Flesch-Kincaid Grade Level — the same formulas behind Word's readability stats and most SEO plugins.
Reading the score
| Score | Difficulty | Roughly matches |
|---|---|---|
| 90–100 | Very easy | 5th grade |
| 70–89 | Easy / fairly easy | 6th–7th grade |
| 60–69 | Standard | 8th–9th grade |
| 30–59 | Fairly difficult / difficult | High school–college |
| 0–29 | Very difficult | College graduate |
Most web content aims for a 60-70 Reading Ease score (roughly 8th-grade level) — easy to skim without feeling written down to. Blog posts and landing pages tend to convert better when they're easier to read, regardless of the audience's actual education level.
How to use the Readability Checker
- Paste a paragraph or a full article.
- Check the Reading Ease score (higher is easier) and the grade level.
- If the score is low, shorten long sentences and swap long words for simpler ones.
Frequently asked questions
What is a good Flesch Reading Ease score?
Most web content aims for 60–70, roughly an 8th–9th grade level. Technical or academic writing is usually lower, and that can be fine for its audience.
Does readability affect Google rankings?
Not directly. Google does not use Flesch scores, but clear writing tends to keep readers on the page, which supports the content being useful.
Why does my score look off for very short text?
The formulas are designed for passages of 100+ words. A single sentence can produce extreme scores.
