About ideal body weight

What this shows

Ideal body weight (IBW) is a reference value derived from height and gender. Clinicians use it as one input among many — alongside body composition, waist measurements and blood markers.

How it is calculated

For heights of five feet and above, this calculator uses the Hamwi method. Below five feet it applies the Broca index.

Reading your result

A range is shown alongside the single figure. Healthy weight is a band, not a point.

Ideal body weight is a reference figure, not a target. It does not account for body composition, frame size or athletic build.
