About This Ideal Weight Calculator
The concept of ideal weight has been used by medical professionals for decades to estimate healthy body weight ranges. This calculator uses established formulas including Devine, Robinson, and Miller to provide a practical range rather than one rigid number.
Because body composition varies widely, the calculator also includes frame size. This helps produce a more realistic estimate for people with naturally smaller or larger builds.
