Ideal Weight Calculator

How this ideal weight calculator works

This calculator uses four established formulas — Devine, Robinson, Miller, and Hamwi — each based on height and gender. It also shows the BMI-based healthy weight range, which is the broadest reference: 18.5 to 24.9 kg/m² multiplied by your height in meters squared.

The formulas

For men (height over 60 inches, H = inches over 5 ft):

• Devine: 50 kg + 2.3 × H
• Robinson: 52 kg + 1.9 × H
• Miller: 56.2 kg + 1.41 × H
• Hamwi: 48 kg + 2.7 × H

For women:

• Devine: 45.5 kg + 2.3 × H
• Robinson: 49 kg + 1.7 × H
• Miller: 53.1 kg + 1.36 × H
• Hamwi: 45.5 kg + 2.2 × H

Results are shown in both pounds and kilograms. Remember that these are estimates — healthy weight varies by frame size, muscle mass, and body composition.
