How healthy weight is calculated
For height h in metres, the weight interval is 18.5h² through 24.9h² kilograms. CDC adult BMI categories apply to adults 20 and older. At 1.70 m, the corresponding weight interval is approximately 53.5–72.0 kg.
BMI reference weight range=18.5×height(m)² to 24.9×height(m)².At 1.70 m, the corresponding weight interval is approximately 53.5–72.0 kg.
Assumptions & useful context
BMI screening range only; not an individual target.
Health calculations are estimates for education. They cannot diagnose a condition or replace a clinician’s assessment. Individual needs vary, especially during pregnancy, illness and growth.
Frequently asked questions
