The so-called "18-yard box" is properly called the Penalty Area. It is 44 yards wide (left and right) and 18 yards deep (from the goal line toward midfield, and the origin of the nickname). The Penalty Area contains the Goal Area (the "six-yard box") and the Penalty Mark (12 yards from the center of the goal, or halfway between the edges of the goal area and penalty area lines).

This arc is not part of the Penalty Area; it just indicates where players cannot be during a penalty kick.
