Ideal weight range (kg)

How is ideal weight calculated?

We use four medically recognised formulas and present the average range. Each formula was developed for different populations and clinical purposes.

Robinson (1983)

Most widely used clinical formula. Based on height above 5 feet.

Miller (1983)

Slightly lighter estimates. Often used in pharmaceutical dosing.

Devine (1974)

The original ideal body weight formula, still used in clinical medicine.

Hamwi (1964)

Oldest formula in widespread use. Adds a frame size adjustment.
