FAQ
Frequently asked questions
Everything you need to know about readability score checker.
Which formulas are included?
Flesch Reading Ease, Flesch-Kincaid Grade Level, Gunning Fog, SMOG, and Coleman-Liau are all calculated from the same text.
What is a good Flesch score?
A Flesch Reading Ease score above 60 is considered easy reading for most audiences, while scores below 30 are difficult and suited to specialized readers.
What do the grade level scores mean?
Grade level formulas estimate the years of formal education needed to understand the text, so a score of 8 means an eighth grade reading level.
Why do the formulas disagree?
Each formula uses different heuristics, such as syllables or letter counts, so they can rank the same text differently. Use the range rather than one number.
Is my text uploaded?
No. All scoring runs locally in your browser, so drafts and documents you analyze never leave your device at any point during the check.
How do I improve my score?
Shorten sentences, replace long words with common synonyms, and break dense paragraphs into smaller ones to lower the grade level and raise readability.
