Flesch Reading Ease (0–100): Higher scores are easier to read. 90–100 = very easy (elementary school), 60–70 = plain English, 30–50 = college level, 0–30 = very difficult.
Flesch-Kincaid Grade Level: Converts the reading ease into a U.S. school grade. A score of 8 means an 8th grader can understand it. Aim for 6–8 for general web content.
SMOG Index: Estimates the years of education needed to fully understand the text, based on polysyllabic words. Recommended for medical and technical writing.
Gunning Fog: Combines average sentence length and the percentage of complex words. Scores above 12 are considered hard to read.
Automated Readability Index (ARI): Uses characters per word and words per sentence to estimate a grade level.
