What is a healthy weight for my height?

A common guide is the weight range that gives a BMI between 18.5 and 24.9 for your height. This calculator works out that range, so you can see the lower and upper healthy weights for how tall you are.

What is the Devine formula?

The Devine formula is a single ideal body weight figure once used for medication dosing. For men it is 50 kg plus 0.9 kg per centimetre over 152, and for women 45.5 kg plus the same. It is shown here as a comparison alongside the BMI range.

Is ideal weight the same for everyone?

No. These are general guides that do not account for muscle, frame size, age, or body composition. A muscular person can be heavy yet healthy. Use the range as a starting point and talk to a health professional for personal advice.

How it works

The healthy range is the weight that gives a BMI of 18.5 at the low end and 24.9 at the high end for your height, found by multiplying each BMI by your height in metres squared. The Devine figure is a separate single estimate based on height and sex.

Worked example

At 175 cm, a healthy BMI range is roughly 57 to 76 kg. The Devine ideal weight for a man of that height is about 70.5 kg. The range is wide because many weights are healthy for a given height.
