    Everything you need to know about readability

    What is a readability score?

    A readability score estimates how easy a piece of writing is to understand. The most common formula, Flesch reading ease, scores text from 0 (very hard) to 100 (very easy) based on average sentence length and syllables per word.

    What is a good readability score?

    For most blog posts and web content, a Flesch reading ease score between 60 and 70 — roughly a 7th to 9th grade reading level — performs best.

    How can I improve readability?

    Shorten long sentences, prefer common words over jargon, break up dense paragraphs, and use active voice.
