Estimates, not verdicts

NHANES data estimate where height, weight, and body mass index (BMI, a measure of weight relative to height) rank among U.S. adults. Relationships among measurements in ANSUR II help generate the plausible bodies used for fit estimates. Product analyses use published dimensions and documented assumptions. Fit Grades is not medical advice, a safety certification, or a substitute for checking critical dimensions.
