There’s no single perfect weight, but these classic formulas and the healthy BMI range give you a sensible target for your height.
How this works
Each formula starts from a base weight at 5 feet tall and adds a fixed amount per inch above that:
- Devine (1974): men 50 kg + 2.3 kg/in, women 45.5 kg + 2.3 kg/in
- Robinson (1983): men 52 kg + 1.9 kg/in, women 49 kg + 1.7 kg/in
- Miller (1983): men 56.2 kg + 1.41 kg/in, women 53.1 kg + 1.36 kg/in
- Hamwi (1964): men 48 kg + 2.7 kg/in, women 45.5 kg + 2.2 kg/in
These were designed for medication dosing and give a single number. The healthy BMI range (18.5–24.9) is a better guide to a healthy weight for most adults.
