FAQs
Which ideal weight formula is most accurate? ›
No single formula is universally best. The Devine formula (1974) is widely used in medicine to determine drug dosages. The Robinson formula tends to be slightly lower. The Miller formula is most commonly cited for women. The Hamwi formula is the oldest (1964) and most conservative. Because they all differ by a few pounds, using the average or the BMI-based range gives a more realistic healthy weight goal than any single formula.
Is ideal weight different for men and women? ›
Yes. All four formulas give different ideal weights for men and women at the same height. Women typically have a lower ideal weight than men at the same height due to differences in average bone density, muscle mass, and fat distribution. For example, at 5'8", the Devine formula gives 154 lbs for men and 140 lbs for women.
