Readability Score Checker
Paste text to calculate its Flesch-Kincaid readability score and grade level. Free to use, no signup required for occasional use.
What is the Readability Score Checker?
The Readability Score Checker analyzes pasted text using the widely used Flesch-Kincaid formulas to estimate how easy or difficult it is to read. It reports a Flesch Reading Ease score (higher means easier to read) alongside an estimated US school grade level, plus a plain-English label like 'Standard' or 'Difficult' so you don't need to interpret the raw numbers yourself. This is useful for writers, marketers, students, and content teams who want their writing to match a target audience's reading level, such as keeping a blog post accessible or a legal summary appropriately formal.
How to use it
Paste your text into the box and click Analyze. The tool calculates sentence and word counts along with syllable estimates, then displays your Flesch Reading Ease score, an estimated grade level, and a plain-English description of what that score means. Aim for a higher reading-ease score and lower grade level if you're writing for a general audience.
Frequently asked questions
What does a higher Flesch Reading Ease score mean?
A higher score (closer to 100) means the text is easier to read; lower scores indicate more complex, harder-to-read text.
How is the grade level calculated?
It uses the Flesch-Kincaid Grade Level formula, which estimates the US school grade a reader would need to easily understand the text.
Is longer text more accurate?
Yes, longer passages give a more statistically reliable score than a single short sentence.
