Ideal Weight Calculator

Find your ideal body weight by height with the Robinson, Miller, Devine and Hamwi formulas and the healthy BMI range.

What is my ideal weight for my height?

Ideal-weight formulas start from a base weight at 5 feet (152.4 cm) and add a set amount for every extra inch. For a 175 cm man, the four classic formulas give about 69–72 kg, and the healthy BMI range (18.5–24.9) is about 57–76 kg.
