A readability score estimates how easy or difficult a piece of text is to understand, based on factors like average sentence length and word/syllable complexity. It is widely used by writers, educators, and content teams to match writing to their target audience.
Most readability formulas produce a score that maps to a US school grade level or an ease-of-reading scale. A lower grade level or higher ease score generally means the text is simpler and more accessible to a wider audience.
It measures how easy your text is to read using the Flesch Reading Ease score and the Flesch-Kincaid Grade Level formula.
A higher score (closer to 100) means the text is easier to read, ranging from "Very Easy" at 90+ down to "Very Confusing" below 30.
The Flesch-Kincaid Grade Level estimates the US school grade level needed to easily understand the text.
It shows word count, sentence count, syllable count, average words per sentence, and average syllables per word.
It uses a vowel-group counting method with adjustments for silent endings, which is the standard approach used by most readability tools since it does not require a full pronunciation dictionary.
