Ideal weight varies by body frame, bone structure, and composition. Our calculator applies four evidence-based formulas (Devine, Robinson, Miller, Hamwi) to provide ranges accounting for individual variation, offering realistic targets versus one-size-fits-all approaches.
Use ranges as guidance, not absolutes. Goals should consider health markers—blood pressure, cholesterol, fitness—beyond weight alone. Frame size, muscle mass, and body composition matter more than a single target.
