About Ideal Weight
Devine Formula (1974)
The Devine formula was originally created for pharmaceutical dosing calculations. For males: 50 + 2.3 × (height_in − 60) kg. For females: 45.5 + 2.3 × (height_in − 60) kg. It is one of the most widely used formulas and is still referenced in medical contexts today.
Robinson Formula (1983)
Robinson's formula modified the Devine formula with slightly different coefficients. For males: 52 + 1.9 × (height_in − 60) kg. For females: 49 + 1.7 × (height_in − 60) kg. It tends to give slightly higher ideal weights for both males and females compared to Devine.
Miller Formula (1983)
The Miller formula provides another variation. For males: 56.2 + 1.41 × (height_in − 60) kg. For females: 53.1 + 1.36 × (height_in − 60) kg. This formula generally produces the highest ideal weights among the three and may be more appropriate for larger frame individuals.
BMI Method
The BMI method calculates the weight range corresponding to a BMI of 18.5 (lower bound) to 24.9 (upper bound) for your height. Weight = BMI × height(m)². This range is often the most flexible as it accounts for individual body composition variations and is endorsed by the WHO.
