Text Readability Score

Readability scores measure how easy a piece of writing is to understand. The Flesch Reading Ease and Flesch-Kincaid Grade Level are the most widely used metrics in publishing, education, and digital content

The calculator uses the standard published formula for readability score. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: Flesch RE = 206.835 - 1.015(words/sentences) - 84.6(syllables/words). Each step in the calculation is shown so you can verify the result manually.
