The Flesch reading ease score estimates how easy a piece of writing is to understand based on sentence length and syllable count per word — shorter sentences with simpler words score higher, meaning easier reading, while longer, denser sentences score lower.
This tool calculates that score along with the corresponding Flesch-Kincaid grade level, a rough estimate of the US school grade needed to comfortably understand the text, both computed instantly as you type.
It's a useful sanity check before publishing content aimed at a general audience — marketing copy, instructions, or web content generally reads best in the 60-80 reading ease range, roughly equivalent to conversational, plain-language writing.

Frequently asked questions
What's a good readability score for a general audience?
A Flesch reading ease score between 60 and 80 is generally considered accessible to most adult readers, corresponding to roughly a 7th-9th grade reading level.
Does a low score mean the writing is bad?
Not necessarily — technical, academic, or legal writing often scores lower by nature, since precision sometimes requires longer sentences and more complex vocabulary than casual writing.
