Understanding the Formulas
Devine Formula (1974)
Originally developed to calculate drug dosages, this is now the most widely used formula for ideal body weight.
Women: 45.5kg + 2.3kg per inch over 5ft
Robinson Formula (1983)
A modification of the Devine formula, often used as a slightly different standard for medical calculations.
Women: 49kg + 1.7kg per inch over 5ft
Miller Formula (1983)
Often yields a lower ideal weight estimate, which some experts believe is more realistic for modern health standards.
Women: 53.1kg + 1.36kg per inch over 5ft
Hamwi Formula (1964)
One of the earliest and simplest formulas, still popular for quick mental estimates.
Women: 45.5kg + 2.2kg per inch over 5ft
