The height would often be not more than six feet, or precisely five feet and ten inches, to participate in the review. A measuring pole was set up in the military camps, and those who did not meet the measure were sent away as unsuitable for the role of a soldier. This aligns with ancient depictions of Roman soldiers, who were mostly of similar types as seen in terms of their height: sturdy and compact men, neither short nor small, but not of the tallest; as illustrated in the bas-reliefs, in the columns of Trajan and Antoninus and other sculptures, show.

The eighth and final length is from the lower leg to the end of the foot, as the depiction sketch simply indicates.
