What Is Readability Score?
Calculate the Flesch-Kincaid reading ease score and grade level of your text.
Readability score measures how easy your text is to understand. The most widely used metric is the Flesch Reading Ease score — a formula based on average sentence length and average syllable count per word. A score of 60–70 is ideal for web content and blog posts (roughly 8th grade level). Academic papers typically score 30–50. Children's books score 80–90.
Knowing your content's readability helps you match the right audience, improve comprehension, and optimize for featured snippets — Google tends to favor clearly written content for answer boxes. Two of the simplest ways to improve your score: shorten sentences and replace multi-syllable words with simpler alternatives.
