Ideal Weight Calculator

See your ideal body weight across four commonly used clinical formulas.

Hamwi Formula (kg)
Devine Formula (kg)
Robinson Formula (kg)
Miller Formula (kg)

Why four formulas?

Different researchers developed different formulas for ideal weight, each with slightly different assumptions. No single formula is universally "correct." Seeing the range from multiple formulas gives a more realistic picture.

Which formula is most accurate?

The Devine formula is most widely used in clinical settings, particularly for drug dosing. The Hamwi formula is common in nutrition counseling. They typically agree within a few kilograms.

Ideal weight formulas provide estimates based on height alone. They do not account for muscle mass, age, ethnicity, or individual health status.
