Ideal weight for your height
The band the four popular formulas agree on. The healthy-BMI range below is wider — a reminder that healthy weight is a range, not a single number.
The ideal weight based on popular formulas
| Formula | Ideal Weight |
|---|---|
| Robinson (1983) | — |
| Miller (1983) | — |
| Devine (1974) | — |
| Hamwi (1964) | — |
| Healthy BMI Range | — |
Classic formulas using height and sex only — reference estimates from different equations, not a diagnosis. They ignore frame size and muscle mass, so read the spread as a guide rather than a target.
Ideal weight for your height
Robinson, Miller, Devine and Hamwi were all derived on adults, so they do not apply at age —. From 2 to 17, healthy weight is judged from BMI-for-age percentiles, which account for the way body fat changes as a child grows — the BMI calculator is the right tool for that.
