What is Body Frame Size?

Body frame size refers to the skeletal mass adjustment in body composition. Since common indices like BMI do not account for body fat levels, measuring body frame size can offer a better understanding of your physique.

How to Measure Your Body Frame Size

To calculate your body frame size, you need to measure your wrist circumference and height. Here is how to measure your wrist:

  1. Use a flexible, non-stretchable measuring tape (around 0.7 cm or 0.3 inches wide).
  2. Wrap the tape around your wrist, just above the knobby bone, and note the measurement.

Body Frame Size Categories

Gender Small Frame Medium Frame Large Frame
Men r > 10.4 r = 9.6 - 10.4 r < 9.6
Women r > 11 r = 10.1 - 11.0 r < 10.1

Use this table to determine your body frame size based on your wrist measurement (r).
