Ideal body weight for your height, from four classic formulas.
Devine, Robinson, Miller and Hamwi are four classic height-based ideal-weight formulas, each with slightly different constants; the Average Estimate is simply the mean of all four.
Each formula starts from a base weight at 5 feet and adds a fixed amount per inch above that — e.g. the Devine formula adds 2.3 kg per inch for men — so results only depend on height and sex, not body composition.
If you enter your current weight, the calculator shows how far it is above or below the four-formula average — it's a reference point, not a specific target you need to hit.
