What the Text Readability Score Calculator Measures and How
The Text Readability Score Calculator shows readability scores for your text, including Flesch Reading Ease and several grade-level formulas. It analyses your text as you type and presents the results live, so the figures are always current. It works out well-known readability scores from your text, including the Flesch Reading Ease score and grade-level formulas such as Flesch-Kincaid, Gunning Fog, SMOG, the Automated Readability Index and Coleman-Liau, using sentence length and syllable counts.
Readability scores estimate how hard a text is to read. The Flesch Reading Ease score runs from 0 to 100, where higher is easier, while the grade-level scores estimate the school grade needed to read the text. Together they help you judge whether your writing suits your audience.
Everything is worked out in your browser as you type. The scores are estimates based on sentence length and syllable counts, which are themselves estimated, so treat them as guides to readability rather than exact measures.
Because it runs on your device, your text is never uploaded. The results appear instantly and privately, with nothing leaving your device. The tool works the same on a phone, tablet or computer, with no account and no limit on how much text you can analyse.
