Results
This calculator uses the Devine ideal body weight formula and is for informational purposes only. It does not replace professional medical advice.
Use this Ideal Weight Calculator to estimate ideal body weight (IBW) from height and sex using the Devine formula. The result is a reference estimate, not a personal healthy-weight target.
Calculation Method
Male: IBW = 50 kg + 2.3 kg × each inch over 5 feet
Female: IBW = 45.5 kg + 2.3 kg × each inch over 5 feet
Example
For a male who is 5 ft 10 in tall:
IBW = 50 + (2.3 × 10)
IBW = 73 kg
This is approximately 161 lb.
Important Note
The Devine formula uses only height and sex. It does not account for body composition, muscle mass, age, pregnancy, medical conditions, or individual health goals. Do not use the result alone to decide whether your current weight is healthy or for medication dosing.
