About Readability Score
This tool helps content creators and developers assess text readability for accessibility and audience targeting. It uses Flesch formulas with approximate syllable counting; results are best used as guidance rather than definitive scores.
Common use cases
- Auditing documentation or help text for readability before release
- Targeting content to a specific reading level for accessibility
- Comparing draft revisions for readability improvements
FAQ
- What does this readability tool measure?
- It computes Flesch Reading Ease (0–100, higher is easier) and Flesch-Kincaid Grade Level (U.S. school grade). Both use word, sentence, and syllable counts with standard formulas.
- Does this tool send my text to a server?
- No. All analysis runs locally in your browser. Your text is never sent to a server or stored.
- Why might my score differ from other tools?
- Syllable counting is approximated with heuristics; different tools use different algorithms. Results are consistent within this tool but may vary across tools.
- What Flesch score should I aim for?
- For general audiences, aim for 60–70 (8th–9th grade). For technical docs, 50–60 is common. Very high scores (80+) indicate very simple text.
