Ideal Weight Calculator

Compare the Devine, Robinson, Miller, and Hamwi ideal-weight formulas alongside the healthy BMI range for your height — because a healthy weight is a range, not a single number.

A Range First, Formulas Second

The primary result is the BMI 18.5–24.9 healthy weight band for your height. The four classic formulas — built decades ago for medication dosing — appear as reference points inside it, not as targets.

Know the Limits

None of the formulas see body composition: a muscular person can be healthy above every formula value. For athletic builds, lean body mass and body fat percentage tell you more.
