Ideal Weight Calculator

Calculate your ideal weight using four evidence-based formulas and see your healthy BMI-based weight range.

Ideal Weight Formulas

FormulaMen (height H in cm)
Robinson (1983)52 + 1.9 × (H/2.54 − 60) kg
Miller (1983)56.2 + 1.41 × (H/2.54 − 60) kg
Devine (1974)50 + 2.3 × (H/2.54 − 60) kg
Hamwi (1964)48 + 2.7 × (H/2.54 − 60) kg

Healthy BMI Range

A BMI of 18.5–24.9 is considered healthy. For a given height, this translates to a weight range:

Healthy Weight = BMI × Height(m)² Min = 18.5 × H², Max = 24.9 × H²

Which formula is most accurate?

No single formula is universally best. The BMI-based range is most widely used. The four traditional formulas were derived for clinical use and may not account for muscle mass or body composition.
