Body Frame Size Calculator

Your details

The wrist ratio is quickest with a tape measure. Elbow breadth, measured with calipers or a ruler across the bent elbow, is the method used in the original height-weight tables.

Measure around the wrist of your dominant hand at the narrowest point, just below the wrist bone toward the hand.

Medium frame, with a healthy weight range of about 56 to 65 kg.

  • Your height-to-wrist ratio is 10.5, which falls in the medium frame band for women.
  • Wrist and elbow are used because they carry little fat or muscle, so they track bone size cleanly. A larger frame carries more weight at the same height.
  • Adjusted for a medium frame, a healthy weight at your height is about 56 to 65 kg.

Next stepCross-check with the elbow breadth method, which the original height-weight tables were built on, by switching the method above.
