Find a healthy target weight for your height with this ideal weight calculator. It shows a sensible weight range rather than one perfect number, based on the healthy BMI band and the Devine formula, and works for both men and women in metric or imperial units.

Frequently asked questions

Why a range instead of one number?
No single weight is "ideal" for everyone of a given height. Build, muscle and frame vary, so a healthy range is more useful and realistic than one figure.
Which formula does it use?
It shows the Devine formula target alongside the weight range for a healthy BMI (18.5 to 24.9), so you can see both perspectives.
Is ideal weight different for men and women?
Yes. For the same height, the formulas give men a slightly higher target than women, reflecting differences in build and muscle. This tool adjusts for the sex you choose.
