Why are there multiple ideal-weight formulas?
Formulas like Robinson, Miller, Devine, and Hamwi were developed independently using different populations and assumptions, so each gives a slightly different estimate for the same height — comparing them shows a range rather than relying on a single number.
Is 'ideal weight' the same as a healthy weight?
Not exactly — these formulas were originally created for drug-dosing calculations, not health guidance. The healthy BMI weight range shown alongside them is generally a more broadly applicable reference.
