What Is Ideal Body Weight?
Ideal body weight is an estimated weight considered healthy for a person's height, calculated with population-based formulas. The Devine formula, for example, is 50 kg + 2.3 kg per inch over 5 feet for men and 45.5 kg + 2.3 kg per inch for women. It was originally developed to calculate medication doses.
Common Formulas
Besides Devine, the Robinson, Miller, and Hamwi formulas give slightly different results. Another common reference is the weight range that corresponds to a BMI of 18.5–24.9.
Limitations
These formulas do not account for muscle mass or body frame and are defined for adults of at least 5 feet (152.4 cm), so they are estimates rather than personal targets.
