Frequently Asked Questions
What is a good readability score?
For general web content, aim for Flesch Reading Ease 60-70 (standard, 8th-9th grade) and Gunning Fog <= 8. Technical writing can score higher.
Which formula should I use?
Flesch Reading Ease is the most popular. Flesch-Kincaid, Gunning Fog, and SMOG give US grade levels. Coleman-Liau and ARI use character counts instead of syllables — more reliable when syllable detection is uncertain.
