Your ideal weight depends on various factors including height, gender, age, and body composition. Our calculator uses four established medical formulas to provide a range of healthy weights for your height.
The results show your ideal weight according to different medical formulas. These are reference values used by healthcare professionals, particularly for medication dosing and nutritional planning.
Each formula has its strengths. The Robinson and Miller formulas are newer adaptations, while Devine and Hamwi are classic methods. The average of all four provides a balanced estimate.
Not necessarily. Ideal body weight formulas are primarily used for medical calculations. For overall health, BMI ranges and body composition are better indicators than a single ideal weight number.
Different formulas use varying calculations and were developed for different purposes. This variation is normal and why we show multiple results to give you a comprehensive range.
While you can use this calculator, people with obesity may need adjusted body weight calculations for medical purposes. Consult your healthcare provider for personalized guidance.
These formulas provide good estimates for average body types but don't account for muscle mass, bone density, or body composition. They're most useful as reference points rather than absolute targets.
