    Readability Score

    A numeric estimate of how easy a text is to read, usually based on sentence length and word complexity.

    Definition

    A readability score is a number that estimates the reading difficulty of a piece of text. The most popular score, Flesch reading ease, runs from 0 (very hard) to 100 (very easy). Other formulas, like Flesch-Kincaid grade level, return a school grade instead.

    Examples

    • A score of 90: easily read by an 11-year-old.
    • A score of 60–70: ideal for most blog posts.
    • A score under 30: typically academic or technical.

    Use cases

    • Editing blog posts before publishing
    • Comparing draft versions during revision
    • Adapting content for different audiences
