The term 'hand measurement' refers to the measurement of a person's hand size. The most common way to measure a person's hand is by using a SPAN, which is the distance between the tip of the thumb and the tip of the little finger when the hand is outstretched. This measurement is usually taken in inches or centimeters. Hand measurements are used for a variety of purposes, such as determining glove size, assessing grip strength, and measuring the size of tools.
