How to Calculate Ideal Body Weight

No single 'ideal' weight exists — multiple formulas estimate a healthy range based on height and sex. Compare several and consider body composition.

Step-by-step

1. Convert height to inches for Devine/Robinson/Miller/Hamwi formulas.
2. Devine (male): 50 kg + 2.3 kg × (height in − 60). Female: 45.5 + 2.3 × (in − 60).
3. Robinson (male): 52 + 1.9 × (in − 60). Female: 49 + 1.7 × (in − 60).
4. Cross-check with BMI range 18.5–24.9 converted to weight at your height.
5. Consider frame size: large frame adds ~10%, small frame subtracts ~10%.
6. Use our Ideal Weight Calculator to compare all formulas at once.
