Ideal body weight formulas

For each inch over 5 ft (152.4 cm): Devine men 50 kg + 2.3 kg women 45.5 kg + 2.3 kg Robinson men 52 kg + 1.9 kg women 49 kg + 1.7 kg Miller men 56.2 kg + 1.41 kg women 53.1 kg + 1.36 kg Hamwi men 48 kg + 2.7 kg women 45.5 kg + 2.2 kg

Worked example

A man 5 ft 7 in (170 cm) tall is 7 inches over 5 ft. Devine gives 50 + 2.3 × 7 = 66.1 kg, Robinson 65.3 kg, Miller 66.1 kg and Hamwi 66.9 kg. The healthy BMI range for his height is 53.5 to 72 kg, so anywhere in that band is a healthy weight.

Frequently asked questions

What is my ideal weight for my height?

Enter your height and sex. The calculator averages four standard formulas and also shows the healthy weight range from a BMI of 18.5 to 24.9.

Which ideal weight formula is best?

The Devine formula is the most widely used in medicine. None is perfect, so a range is more useful than one number.

Why are the results different for men and women?

Women generally have less muscle and bone mass than men of the same height, so the formulas start from a lower base weight.

Does ideal weight include muscle?

No. Muscular people can be healthy above these numbers. Body fat percentage is a better check for them.

What is the ideal weight for 5 ft 6 in?

About 59 kg for women and 64 kg for men by the Devine formula, with a healthy BMI range of roughly 52 to 70 kg.
