Ideal Weight Formulas Explained

Why Multiple Formulas?

No single formula suits every body type. The Devine formula is used clinically in medication dosing. Robinson and Miller were developed to address Devine's limitations. The BMI range (18.5–24.9) gives the broadest healthy window.

Body Frame Size

Larger-framed people naturally carry more weight without being overweight. Wrist circumference relative to height is a simple way to estimate frame size — a rough guide only.

The Practical Takeaway

Rather than chasing a single number, aim for the BMI healthy range (18.5–24.9). This typically spans 10–15 kg, giving your body the flexibility it needs.
