About Ideal Weight Calculator
The Ideal Weight Calculator estimates your optimal body weight using four established medical formulas developed between 1871 and 1983: Devine, Robinson, Miller, and Hamwi. Each formula takes a slightly different approach to calculating ideal weight based on height and gender, typically starting with a base weight for five feet of height and adding incremental weight for each additional inch. The Devine formula was originally developed for medication dosing calculations, the Robinson formula was derived from life insurance data, the Miller formula updated the concept for modern populations, and the Hamwi formula offered a simple clinical shortcut. Since these formulas can produce varying results, the calculator presents all four side by side for comparison. It also computes your healthy weight range based on the BMI standard of 18.5 to 24.9, giving you a broader perspective on where a healthy weight might fall for your specific height. Use the results as general reference points rather than absolute targets, as individual healthy weights vary based on muscle mass, bone density, and body composition.
