What is the Flesch Reading Ease Score?
The Flesch Reading Ease score is a readability formula that outputs a number from 0 to 100. Higher scores mean the text is easier to read. Developed by Rudolf Flesch in 1948, it uses two inputs: average sentence length and average number of syllables per word. Unlike grade-level formulas, the reading ease score gives you a single scale that’s easy to compare across documents—for example, a score of 65 is “standard” difficulty, while 80 is “easy.”
Writers and editors use the Flesch Reading Ease calculator when they want to know how accessible a piece of text is without translating that into a U.S. school grade. It’s common in content marketing, technical writing, and policy documents where a 0–100 scale is more intuitive than “8th grade level.” Many style guides and organizations set targets in reading ease (e.g. “aim for 60 or above”) rather than grade level.
What Is a Good Flesch Reading Ease Score?
For general audiences, a score of 60–70 is often considered good—readable but not oversimplified. Scores of 70–80 are easier and work well for consumer content, health information, or broad public outreach. Scores below 30 are typically very difficult (academic or legal style). Use the calculator above to see where your text lands and adjust sentence length and word choice to move up or down the scale as needed.
When to Use Flesch Reading Ease
Use a Flesch Reading Ease calculator when you need a quick, widely understood measure of how easy your text is to read. It’s ideal for comparing drafts, setting internal readability targets, or meeting guidelines that specify a reading-ease range. Because the same formula also underlies Flesch-Kincaid grade level, this tool gives you both the 0–100 score and the equivalent grade level on one page.
