Two people of the same height can have very different healthy weights because of their bone structure. Measure your wrist to find your frame size and the weight range that suits it.
How this works
Frame size uses the ratio of height to wrist circumference (both in the same units), measured just below the wrist bone on the side you write with.
- Men: over 10.4 small, 9.6–10.4 medium, under 9.6 large
- Women: over 11.0 small, 10.1–11.0 medium, under 10.1 large
The healthy weight shown is the part of the healthy BMI range (18.5–24.9) that typically suits each frame: the lower third for small frames, the middle for medium and the upper third for large.
