Reading Level Checker
Estimate the grade level and readability of your writing using the Flesch-Kincaid formulas.
Runs your text through the Flesch Reading Ease and Flesch-Kincaid Grade Level formulas — the same readability measures used by many word processors and content-scoring tools — based on average sentence length and syllables per word, to estimate how easy your writing is to follow and roughly what US grade level it's pitched at.
Example: A Reading Ease score of 62 lands in the "Standard" band (roughly 8th-9th grade) — the level most general-audience news writing aims for.

Frequently asked questions
How accurate is the Flesch-Kincaid score?
It's a well-established estimate based on sentence length and syllable count, not a full comprehension study — treat the grade level as a useful approximation, not an exact measurement, especially for very short or technical text.
Is my text uploaded anywhere?
No — Reading Level Checker runs entirely in your browser using JavaScript/WebAssembly. Your text is never sent to a server.
Does this work for languages other than English?
No — the Flesch-Kincaid formulas were developed for English and rely on English syllable-counting patterns, so scores on non-English text won't be meaningful.
