Ideal Weight Formulas

Multiple formulas exist. Robinson (1983), Miller (1983) and Devine (1974) are commonly used. Results differ slightly — use them as a range guide.

Is ideal weight the same as healthy weight?+

Not exactly. Healthy weight considers BMI range (18.5–24.9). Ideal weight formulas focus on height-based calculations.

What if I am muscular?+

Muscular individuals often exceed formula-based ideal weight ranges. Body composition matters more than weight alone.
