This tool allows you to determine your ideal body weight (IBW) according to 5 different methods based on height.
The results are only adequate for adults age 18 or older.

 Hamwi (1964). The Hamwi method for calculating the IBW is as follows:
 Male IBW (kg) = 48 + 2.7 × (Ht − 60 in)
 Female IBW (kg) = 45.5 + 2.2 × (Ht − 60 in)
 Devine (1974). The Devine equations for calculating the IBW is as follows:
 Male IBW (kg) = 50.0 + 2.3 × (Ht − 60 in)
 Female IBW (kg) = 45.5 + 2.3 × (Ht − 60 in)
 Robinson (1983). The Robinson formula for calculating the IBW is as follows:
 Male IBW (kg) = 52 + 1.9 × (Ht − 60 in)
 Female IBW (kg) = 49 + 1.7 × (Ht − 60 in)
 Miller (1983). The Miller equations for calculating the IBW is as follows:
 Male IBW (kg) = 56.2 + 1.41 × (Ht − 60 in)
 Female IBW (kg) = 53.1 + 1.36 × (Ht − 60 in)
 Body Mass Index (BMI)
 Male or Female IBW (kg): 18,5 x Ht(cm) ^ 2 < IBW < 25 x Ht(cm)^2
 Hamwi (1964). The Hamwi method for calculating the IBW is as follows:
IBW equations are used by clinicians to calculate drug dosing, to estimate overweight and underweight statuses, and to calculate nutrient intakes.
The most common estimation of IBW is by the Devine formula, but the other models give similar results.
The IBW is not the perfect fat measurement as it does not show the fat or muscle percentage in one's body. For example, athletes' results show that they are overweight when they are actually very fit and healthy.
