BMI & Healthy Weight Range
Estimate adult BMI and a standard healthy-weight range.
About This Calculator
Estimate adult body mass index and the standard healthy-weight range for a given height.
How It Works
BMI divides weight in kilograms by height in meters squared. The healthy-weight range uses adult BMI values from 18.5 through 24.9.
BMI = weight (kg) ÷ height² (m²)
Example
An adult who is 5 ft 9 in and weighs 170 lb has a BMI of approximately 25.1.
Important Notes
BMI is a screening measure, not a diagnosis. It does not directly measure body fat and may be less informative during pregnancy, in children, older adults, or highly muscular people. Discuss health concerns with a qualified clinician.
