Review how demanding an English passage may be for readers. This Content Readability Checker estimates Flesch reading ease and Flesch–Kincaid grade level, alongside word counts, sentence counts, average sentence length, and estimated reading time.
How to Use Content Readability Checker
- Paste an English passage with enough text to provide context.
- Review the reading estimates and average sentence length.
- Simplify unclear wording while preserving necessary technical detail.
- Run the revision again and read it manually to confirm clarity.
Make website copy easier to follow
Use readability estimates to compare versions of the same draft. Shorter sentences, clear transitions, and familiar words can help readers understand instructions. A technical article may still need specialist terms, so the right wording depends on the audience and purpose of the page.
Example: simplify an instruction
Instead of a long sentence covering preparation, action, and exceptions together, separate the instruction into two or three steps. Then run both versions through the checker and review the difference in average sentence length. Read the revised text aloud to confirm that it still communicates the same information.
Understand the limits of the estimates
The tool estimates English syllables and sentence boundaries. Abbreviations, proper names, short passages, and unusual punctuation can affect the calculation. A grade estimate is not an assessment of a reader or a certification of accessibility. The tool does not establish that a page is factually correct or helpful.
Use the Keyword Density Checker to inspect repetitive wording and the Heading Structure Checker to review the organization of pasted HTML.
