Clear writing wins readers. The Readability Checker on ToolOrbit tells you, with a number, how hard your text is to read. Paste a paragraph or a whole article and get the Flesch Reading Ease score, the Flesch-Kincaid grade level, and supporting stats in one glance.
How readability scoring works
The tool uses two well-established, math-based formulas. They are not AI judgments. They are arithmetic over your text, counting words, sentences, and syllables, then plugging those counts into published equations.
Flesch Reading Ease returns a score from roughly 0 to 100. Higher means easier. A score of 60 to 70 is plain English suitable for most adults; below 30 is dense and academic. Flesch-Kincaid converts the same inputs into a US school grade level, so a result of 8 means an eighth grader could follow it.

206.835 - 1.015 * (words / sentences)
- 84.6 * (syllables / words)How to use the Readability Checker

Everything is calculated in your browser. No text is sent anywhere, so you can check confidential drafts safely and instantly.
Tips to improve your readability score
- Shorten long sentences. Splitting one 40-word sentence into two is the fastest way to raise your score.
- Prefer shorter, common words over long ones. Syllable count drives the formula heavily.
- Aim for a grade level around 7 to 9 for general web audiences; technical readers tolerate higher.
- Do not chase the number blindly. Some terms cannot be simplified, and clarity sometimes needs a longer sentence.
Who benefits from readability scoring
Bloggers, marketers, support teams, and students all use readability scores to match writing to their audience. Many style guides and content platforms target a specific grade level, and this tool lets you verify yours before you publish.
Remember that the Readability Checker grades form, not substance. Pair its numbers with your own editorial judgment, and you will produce writing that is both clear and worth reading, all without a single byte leaving your device.
