Devine, Robinson, Miller and Hamwi use different base weights and per-inch adjustments. There is no single universally correct ideal-weight formula, so comparing them is more informative than presenting one result as exact.
They are four established formulas for estimating ideal body weight based mainly on height and gender.
Devine - Originally developed in 1974 to estimate medication dosing weight and later became widely used as an ideal-weight reference.
Robinson - Developed in 1983 as a variation using slightly different values from Devine.
Miller - Developed in 1983 and uses another variation of the height-based calculation.
Hamwi - An older formula from 1964, commonly used as a quick clinical estimate of ideal body weight.
Because each formula calculates weight slightly differently, Wid9et shows all four rather than pretending there is one exact "ideal" weight.
These historical equations were published with separate male and female constants. The selector chooses which published constants to use; it is not an assessment of your health or body composition.
No. These formulas are rough adult reference estimates and do not replace individual medical or nutritional advice. They are also not designed for children.
