About "ideal" weight

There's no single perfect weight — several formulas have been proposed over the decades, each derived from different populations. This tool shows the classic Robinson, Miller, Devine and Hamwi formulas plus the weight range that corresponds to a healthy BMI of 18.5–24.9 for your height.

These figures are rough guides. Body composition, frame size, age and muscle mass all matter, so use the results as a ballpark rather than a target.
