Ideal Weight Calculator
Find your ideal body weight range from height using established medical formulas.
About the Ideal Weight Calculator
What should you weigh for your height? There is no single answer, but several medically established formulas converge on a sensible range. The AlarmDaddy Ideal Weight Calculator computes your ideal weight using the Robinson, Miller, Devine, and Hamwi formulas, plus a healthy-BMI-based range, and presents them together so you can see a realistic target band rather than a single arbitrary number.
Enter your height and sex. The calculator returns each formula's estimate and an overall healthy range. Use it as a goalpost, not a verdict — frame size, muscle mass, and body composition all shift the ideal. It pairs naturally with the BMI and body-fat calculators.

The formula
These classic formulas all start from a base weight at 5 feet of height and add a fixed amount per inch above that. They differ slightly in their constants. The calculator also derives a range from the healthy BMI band (18.5–24.9) for your height.
