About this calculator

Unlike BMI, which produces a category from a height-to-weight ratio, this calculator uses older reference formulas developed to estimate a single target weight figure based mainly on height and sometimes frame size or sex. These formulas were originally created for specific clinical purposes such as medication dosing rather than as general fitness targets, so results are best treated as a rough reference point rather than a strict goal.

People use it out of curiosity when comparing their own weight to a commonly cited reference number, and it sometimes comes up in fitness planning discussions alongside other measures like BMI or body fat percentage, since no single number captures the full picture of a healthy body weight for an individual.
