Ideal Body Weight Calculator
There is no single perfect weight for any height. This calculator estimates your ideal body weight using four of the most commonly used clinical formulas so you can see the range of recommendations.
The Devine formula (1974) is the most widely used ideal body weight equation and was originally developed for drug dosage calculations. It estimates: Men = 50 + 2.3 kg per inch over 5 feet; Women = 45.5 + 2.3 kg per inch over 5 feet. This calculator also includes the Robinson (1983), Miller (1983), and Hamwi (1964) formulas for comparison. All of these formulas were developed from population studies and may not account for individual differences in body composition, frame size, or ethnicity. The healthy BMI weight range (18.5–24.9) is also provided as an additional reference point.
