About ideal weight calculator
Ideal weight formulas give a rough reference range for a given height and sex. This tool uses the Devine formula.
Devine formula
For men: 50 kg + 2.3 kg for every inch over 5 feet. For women: 45.5 kg + 2.3 kg for every inch over 5 feet. A 5 ft 10 in man gets about 73 kg.
Remember
These formulas were designed for medication dosing, not as a health target. Frame, muscle, age and health conditions matter. Treat the result as one reference alongside BMI and how you feel.
A worked example
A woman who is 5 ft 4 in tall is 4 inches over 5 feet, so the Devine formula gives 45.5 + 2.3 × 4 = 54.7 kg. Treat a range of about 10 percent either side of this as a reasonable reference.
