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.
Flesch Reading Ease =
206.835 - 1.015 * (words / sentences)
- 84.6 * (syllables / words)Checking the reading level of your text
- Paste your text into the input box.
- Read the Reading Ease score and the Flesch-Kincaid grade level.
- Check the supporting stats: word count, sentence count, and average sentence length.
- Edit, then re-check to watch the score improve.
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.
Which metric to report, and to whom
| Metric | Measures | Good if |
|---|---|---|
| Flesch Reading Ease | Easy to read (0–100, high = easy) | 60+ for general copy |
| Flesch-Kincaid Grade | School grade level years needed | ≤ 8th grade for web |
Reporting both answers two different questions: the readable-feel (ease, 0–100) and the education level implied (grade). Government and health web-writing standards commonly target a grade level of 8 or lower, and that discipline transfers to marketing copy: at grade 12, you are writing for about a third of the general reading public. Run the checker after editing, not during — the sentence-level edit loop keeps you in the flow and identifies the residual hard patches afterwards.
