Ideal Weight vs BMI: Which Is a More Useful Health Metric?

Ideal weight calculators estimate a target weight range based on height, using formulas developed by Devine (1974), Robinson (1983), Miller (1983), and Hamwi (1964). Unlike BMI, they produce a weight target rather than a category classification.

BMI is more widely used and validated at population scale, but ideal weight formulas can be more actionable for individuals — they tell you what weight to aim for, not just which category you are in.
