About the Ideal Weight Calculator
"What should I weigh?" has several legitimate answers. This calculator shows four classical clinical formulas — Devine, Robinson, Miller and Hamwi — side by side for your height and sex, alongside the full healthy-BMI weight range (18.5–24.9). Where the formulas cluster, that is a sensible target zone; where they disagree, the BMI range is the fairer guide. Treat all of it as orientation, not obligation — body composition matters more than any single number.
