Height as a comparative metric
Human height follows a roughly normal distribution in most populations, with average male heights ranging from about 164–178 cm and female heights from about 154–168 cm depending on country and birth cohort. Comparing heights within a group can reveal meaningful differences in physical dimensions that affect performance, ergonomics, and medical reference ranges.
This tool calculates each person's rank from tallest to shortest, their difference from the tallest and shortest in the group, and the overall group average — all in both centimetres and feet-and-inches.
