Worth Knowing
Frame size, judged here from the ratio of height to wrist circumference, helps explain why two people of identical height can have genuinely different healthy weights — a large-framed person carries more bone and structural mass. It's the missing variable that makes single-number 'ideal weight' formulas misleading. The wrist is used because it's almost entirely bone and skin with little fat or muscle to distort the measurement, making it a stable proxy for overall skeletal size.
