About the Formulas
The four formulas used in this calculator were developed by medical researchers to estimate ideal body weight based on height and sex. Each formula uses slightly different coefficients, providing a range of ideal weights rather than a single number. The Devine formula (1974) is the most widely used in clinical settings, while Robinson (1983), Miller (1983), and Hamwi (1964) offer alternative estimates.
