Healthy Weight Calculator
See the healthy weight range for your height, based on a BMI of 18.5 to 24.9.
About the Healthy Weight Calculator
The World Health Organization defines a healthy weight for adults as a body mass index from 18.5 to 24.9. Multiplying those limits by your height squared gives the weight range. Some guidance uses lower cut-offs for people of South Asian, Chinese and other Asian heritage (overweight from BMI 23).
The formula
Healthy weight = 18.5 × height² to 24.9 × height² (kg, m)
Worked example
Example: Healthy weight for your height = 177 lb – 238 lb
- Inputs: Units: lb / ft; Height: 6 ft; and: 10 in; Weight: 180 lb.
- Formula: Healthy weight = 18.5 × height² to 24.9 × height² (kg, m)
- Result: Healthy weight for your height = 177 lb – 238 lb
- Your BMI: 18.8
- Middle of the range (BMI 21.7): 208 lb
Things to keep in mind
- This is an estimate for general information, not medical advice. Talk to a doctor or other qualified professional about your health.
- BMI doesn't distinguish muscle from fat and isn't designed for children or pregnancy.
Questions people ask
Why a range instead of one number?
Healthy bodies vary in build and muscle; risk is similar across the whole range.
Do Asian adults use the same range?
Many health bodies, including the WHO expert consultation, suggest action from BMI 23 for Asian populations.
