How Does the Body Frame Size Calculator Work?
Divides total standing height by wrist circumference to yield a standard frame coefficient.
Body Frame Size Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Frame Ratio (r) = Height (cm) / Wrist Circumference (cm)
The Metropolitan Life Insurance standard ratio classifying skeletal framework.
