Earlier we described various types of hands, determined by the structure and shape of the fingers as a whole; then we talked separately about the thumb, now let's move on to the description of other specific fingers. The length of the fingers can be determined by comparing it with the back of the hand. Put your hand - best left - horizontally with your palm down, squeezing your fingers, and pay attention to the joint through which the ulnar bone connects to the wrist. Measure the distance in centimeters and millimeters from the center of this tubercle to the knuckle of the middle finger. It will be a measure in determining the length of the fingers.
