Ideal Weight Calculator
A healthy-weight range from BMI plus medical reference formulas (Devine, Robinson, Hamwi, Miller).
There is no single "ideal weight." A healthy range is typically defined by BMI 18.5–24.9 for your height, for a 5'10" adult that's about 129–174 lb. Medical reference formulas (Devine, Robinson) give a single number used for drug dosing.
