About this tool
This page opens the ideal weight calculator preset for women, so the four classic formulas — Devine, Robinson, Miller and Hamwi — apply their female-specific coefficients the moment you enter your height. Each equation was derived separately for men and women, and the female versions use a lower base weight at 5 feet and a smaller increment per inch above it, reflecting the reference bodies the original studies measured.
Because the formulas were built decades ago from clinical populations of their time, they don't account for factors that matter for many women today, such as pregnancy, bone density changes around menopause, or an athletic build with above-average lean mass. The healthy BMI weight range shown alongside the four formulas is a useful second opinion precisely because it doesn't assume anything about body composition, only height.
Enter your height in centimeters to see all four formula results plus the BMI range at once, rather than anchoring on whichever single number you saw first elsewhere. If a formula's estimate and the BMI range disagree, or if the number simply doesn't match your own health context, the range and a conversation with a healthcare professional are more reliable guides than any one 1980s equation.
Example. A height of 177.8 cm for male sex returns a Devine weight of 73.0 kg.
Limit. Height must be from 100 cm to 250 cm, and the four formulas are omitted when the height is under 5 feet.
