Ideal Weight Calculator
Compare four ideal-weight formulas and the healthy BMI range for your height.
Healthy weight range (BMI 18.5–24.9)
| Formula | kg | lb |

About these formulas: Robinson (1983), Miller (1983), Devine (1974) and Hamwi (1964) were designed to estimate drug doses, so they only use height and sex and don’t account for muscle, frame size or age. The healthy BMI range is wider and more widely used. Treat all of them as a rough guide rather than a target.

Frequently asked questions
What is the healthy weight range for my height?
The range that gives a BMI between 18.5 and 24.9. For someone 175 cm tall, that is about 57–76 kg.
Which ideal weight formula is the most accurate?
None is perfect. They were designed for medication dosing and ignore muscle and frame size, so they give different answers. The healthy BMI range is the most widely used guide.
Does ideal weight account for muscle?
No. Muscular people can be healthy above these figures. Body fat percentage and waist size tell you more.
