The standard measurement begins at the starting point (located near the first wrist crease and aligned with the starting point of the lifeline). From there, measure along the curved line that follows the base of the fingers. This line is divided into two-thirds and one-third sections, and the glove size is based on the total length of this palm circumference line.
