Frequently asked questions
It inverts the BMI formula: for your height, the weights that produce a BMI of exactly 18.5 and 24.9 — the edges of the WHO normal band — form the range.
Healthy bodies at the same height vary with frame, muscle and fat distribution. A roughly 35–40 lb band is more honest than any single 'ideal' figure.
Not necessarily. BMI bands are population screening cut-offs; athletes, older adults and others can sit outside them and be healthy. Context and trend matter.
No — under-20s are assessed with BMI-for-age percentiles (CDC), not the adult 18.5–24.9 band. Use the BMI Calculator for Kids.
