How to find your ideal weight

Quick answer: To find your ideal weight, choose sex and units and enter your height.

  1. Choose sex and units. The formulas differ for men and women.
  2. Enter your height. All four results and the healthy range appear.

Why four answers?

Each formula was made for a different purpose (Devine for medicine doses, for example). Looking at all four and the BMI range gives a sensible target zone rather than one magic number.

Frequently asked questions

Which formula is best?

None is perfect. The healthy BMI range (18.5–24.9) is the widely used guide; frame size and muscle matter too.
