Frequently Asked Questions

This calculator uses four well-known formulas: Devine (1974), Robinson (1983), Miller (1983), and Hamwi (1964). Each was developed from clinical data and provides slightly different ideal weight estimates.

No single formula is perfect. The Devine formula is most commonly used in medicine for drug dosing. Looking at the range from all four formulas gives a more realistic healthy weight target.

Ideal weight formulas provide estimates based on height and gender only. They don't account for muscle mass, bone density, or body composition. A person with more muscle may weigh more than their 'ideal' weight and still be very healthy.
