The Braccio is a traditional Italian measurement of length. The word means "arm", and a Braccio is approximately equal to the length of a man's arm, about 27 or 28 inches (68-71 centimeters). In modern times, the Braccio has become an informal metric unit of exactly 70 centimeters (about 27.56 inches), which is the same as the Arm Length unit.
