Ideal Weight Formulas

There is no single universally accepted formula for ideal body weight. This calculator shows four widely used formulas: Hamwi (1964), Devine (1974), Robinson (1983), and Miller (1983). The results are guidelines, not prescriptions.

Body composition, muscle mass, and overall health are far more meaningful measures than any single target weight number. Use these ranges as a starting point for conversations with your healthcare provider.
