Devine formula
Men: 50 kg + 2.3 kg × (inches over 5 ft) · Women: 45.5 kg + 2.3 kg × (inches over 5 ft)
Several formulas exist (Devine, Robinson, Miller, Hamwi), so we show a range rather than one number — "ideal" weight is a guideline, not a target. Frame size, muscle mass and body composition all shift what's healthy for you.
What "ideal weight" really means
Ideal body weight formulas were created to help dose medication and later adopted as general references. Because they disagree slightly, we show four (Devine, Robinson, Miller, Hamwi) plus their average and the healthy-BMI weight range for your height. Enter your height in any unit — feet & inches, cm or m.
