Ideal Body Weight Calculator
Science-based ideal weight range for your height using multiple formulas.
Which formula is right?
No single formula is definitive. The Devine formula (1974) was originally designed for drug dosing, not aesthetics. The healthy BMI range (18.5–24.9) is the most clinically accepted guide.
Limitations
These formulas don't account for muscle mass, bone density, or body fat distribution. A muscular 200 lb person and a sedentary 200 lb person have the same "ideal weight" calculation but very different health profiles.
Body composition matters more
Waist circumference below 35 inches (women) or 40 inches (men) is a stronger predictor of metabolic health than scale weight alone.
