About this calculator
An ideal weight calculator gives a target weight for your height and sex using well-known clinical formulas (Devine, Robinson) plus the healthy-BMI range. There is no single perfect number — use the range as a guide.
Frequently asked questions
Which ideal weight formula is best?
They mostly agree within a few kilograms. The Devine formula is the most widely used clinically, but a healthy BMI range (18.5-24.9) is a more modern guide.
Is ideal weight the same as a goal weight?
Not necessarily. These formulas ignore muscle mass and body composition, so an athletic person may sit above their ideal figure while being perfectly healthy.
