Enter your height and sex to see an ideal body weight reference based on the Devine formula.

The idea of an ideal weight

Ideal body weight formulas were created decades ago, often to guide medication dosing rather than to set personal goals. The Devine formula used here gives a reference figure based only on height and sex, which makes it simple but blunt.

Because it ignores build, muscle, and age, no single number can be right for everyone of a given height. Read the result as a rough population reference, not a target to chase. Healthy weight is a range, and it is best discussed with a professional who knows your full picture.

The formula

Men: 50 kg + 2.3 x (inches over 60); Women: 45.5 kg + 2.3 x (inches over 60)

Worked example

A man 175 cm tall (about 69 inches) has a reference ideal weight of about 70 kg.

How to read your result

Ideal weight formulas give a rough population reference, not a personal target. Healthy weight varies with build, muscle, and many other factors.
