A range, not one number
There's no single perfect weight. The healthy BMI range of 18.5 to 24.9 gives a band of weights that suit your height. Where you sit in it depends on your build, muscle and age.
Lowest = 18.5 × height (m)²Highest = 24.9 × height (m)²The ideal weight formulas
Each formula starts from a base weight at 5 ft (152.4 cm) and adds a set amount for every inch above that. Devine's was first made to work out medicine doses; Robinson and Miller later refitted it to population data, and Hamwi's comes from dietetics.
Devine: 50 kg (men) or 45.5 kg (women) + 2.3 kg per inchRobinson: 52 kg + 1.9 kg (men) or 49 kg + 1.7 kg (women) per inchMiller: 56.2 kg + 1.41 kg (men) or 53.1 kg + 1.36 kg (women) per inchHamwi: 106 lb + 6 lb (men) or 100 lb + 5 lb (women) per inchGood to know
The formulas were designed for adults at least 5 ft tall. They don't account for muscle, frame size or age, which is why they disagree with each other. Treat them as a rough guide and the BMI range as the wider picture.
