Calculate Your Ideal Body Weight
Find your ideal weight range using multiple formulas: Devine, Robinson, Miller, and Hamwi. Based on height, frame, and gender.
Multiple Ideal Weight Formulas
No single formula perfectly defines "ideal" weight — body composition, muscle mass, and individual factors matter enormously. This calculator uses four established medical formulas to give you a range: Devine (1974): Most widely used in clinical settings. Robinson (1983): Updated version of Devine. Miller (1983): Tends to give slightly higher results. Hamwi (1964): The oldest formula. The range across all four formulas gives a more realistic target than any single number.
Why "Ideal Weight" Is Complicated
These formulas were designed for medical dosing and insurance tables — not as absolute health targets. A muscular 5'10" person at 190 lbs may be healthier than a sedentary person at the "ideal" 160 lbs. Body composition (muscle vs fat), waist circumference, and metabolic health markers are better indicators than scale weight alone. Use this calculator as a general reference, not a rigid goal.
Research consistently shows that health outcomes depend more on fitness level than weight. A study in the European Heart Journal found that fit overweight individuals had lower mortality risk than unfit normal-weight individuals. Focus on exercise, nutrition quality, and metabolic health markers rather than obsessing over a number on the scale.
