This calculator estimates Ideal Body Weight using the Robinson (1983) equation based on your height and sex, a method widely used in clinical contexts such as medication dosing.
It also shows your Healthy Weight Range using the standard BMI “normal” category (18.5 to 24.9 kg/m²), so you can see a practical lower and upper target weight for your height.
The calculator is intended only for people from the age of 18 and older and not pregnant.
