Ideal Weight Calculator

Estimate a healthy weight range using the Devine, Robinson, and Miller formulas.

How the Ideal Weight Calculator Works

This calculator estimates your ideal body weight based on your height and gender using the three most popular formulas: Devine, Robinson, and Miller. These formulas estimate healthy body weight ranges used in medical settings.

Formula Used

Devine (Male) = 50.0 + 2.3 × (Height in inches − 60) Devine (Female) = 45.5 + 2.3 × (Height in inches − 60)
Height
— measured in inches (60 inches is the baseline, equivalent to 5 feet)
2.3 kg
— the ideal weight added for every inch of height above 5 feet

Example Calculation

For a female who is 5 feet 5 inches tall (65 inches total): Devine = 45.5 + 2.3 × (65 − 60) = 45.5 + 11.5 = 57.0 kg. The calculator displays the ranges computed across all three formulas.
