Ideal Weight
Ideal weight calculator
A common estimate is the Devine formula (≈50 kg men / 45.5 kg women at 5 ft, +2.3 kg per inch above). Alongside it, a healthy weight range is whatever gives a BMI of 18.5–24.9 for your height. Enter your height for both — remember a healthy weight is a range, not one number.

Frequently asked questions
What's my ideal weight for my height?
Devine formula: ~50 kg (men) / 45.5 kg (women) at 5 ft, +2.3 kg per inch above. Plus a healthy range = BMI 18.5–24.9 for your height.
Is there one correct number?
No — healthy weight is a range depending on build and muscle. Muscular people can be heavier and still healthy.
How is the range calculated?
18.5 and 24.9 × height(m)² give the low and high ends of a normal-BMI range.
