About Readability Checker
What this tool does
Readability Checker estimates how easy your text is to read — reading ease, grade level and average sentence length.
How to use it
- Paste your content.
- Read the reading-ease score, grade level and sentence stats.
- Simplify sentences that drag the score down.
How it works
It counts words, sentences and syllables and applies standard readability formulas to estimate reading ease and an approximate US grade level.
Important considerations
- Readability formulas are estimates based on sentence and word length, not meaning or tone.
