Preguntas Frecuentes — Ideal Weight Calculator
Which ideal weight formula is most accurate?
No single formula is universally accurate for all body types. Hamwi and Devine are traditional clinical formulas, Robinson is a refined version, and Miller tends to produce slightly lower estimates. The average across all four provides a reasonable target range.
Is ideal weight the same as healthy weight?
Not exactly. Ideal weight formulas give a target based on height and sex but do not account for muscle mass, bone density, or body composition. A person can be above the formula's ideal weight but still be perfectly healthy, or below it and still have excess body fat.
How is ideal weight different from BMI healthy weight?
BMI healthy weight is the range where your BMI falls between 18.5 and 24.9. Ideal weight formulas use height-based regression equations developed in clinical settings. Both are shown together in this calculator so you can compare them.
