About the Readability Check Tool
Readability formulas estimate how difficult a text is by measuring sentence length and word complexity. The Flesch Reading Ease score runs from 0 to 100, where higher is easier — around 60–70 sits comfortably for general audiences, while below 30 indicates genuinely demanding academic prose.
The Flesch-Kincaid Grade Level expresses the same analysis as years of schooling required. These are useful as objective indicators when you are writing for a broad audience, and particularly when you suspect your writing has drifted more technical than intended. Analysis runs in your browser.
How to Use Readability Check
- Paste your text into the input area.
- The readability scores are calculated immediately.
- Compare the result against your target audience level.
- Shorten sentences and simplify vocabulary, then re-check.
When to Use This Tool
- Checking whether web copy is accessible to a general audience
- Ensuring public-facing documentation is not unnecessarily technical
- Editing content to meet a specified reading level requirement
- Assessing educational material against its intended year group
- Simplifying writing aimed at non-native English readers
Things Worth Knowing
- Formulas measure sentence and word length only. They cannot assess whether the content is actually clear.
- Technical vocabulary lowers the score even when the terms are necessary and familiar to the audience.
- Treat the score as a signal to review, not a target to optimise blindly.

Frequently Asked Questions
What is a good Flesch Reading Ease score?
60–70 is comfortable for a general adult audience — roughly the level of a broadsheet newspaper. 30–50 indicates fairly difficult text; above 80 is very easy, suitable for younger readers.
How is the score calculated?
From average sentence length and average syllables per word. Longer sentences and more polysyllabic words both lower the score, indicating greater difficulty.
Does readability affect SEO?
Not as a direct ranking factor. It affects whether people actually read and stay on your page, and engagement signals do influence how content performs over time.
Should I always aim for the highest score?
No. Optimising the number alone produces choppy, oversimplified prose. Write for your actual audience — a specialist readership does not need every sentence shortened.
