An end zone is one of the two areas at the end of the playing field in Ultimate Frisbee where teams can score a goal by catching the disc there. It is separated from the central zone by the goal line. The cones at the front and rear of the end zone along the sideline are relevant when a player is close to the sideline within the end zone. The end zone being attacked is the one in which the team is currently attempting to prevent the opposition from scoring.

The lines that are part of the field in Ultimate frisbee are the two sidelines along the length and the two endlines along the width.

The field in Ultimate frisbee is 100 meters long by 37 meters wide. It is divided into a central zone that is 64 meters long and two end zones that are 18 meters deep at each end of the central zone. The lines on the field should be between 75 and 120 millimeters wide and marked with a non-caustic material. If there is not enough space for a full-sized field, the end zones should be made shorter before reducing the central zone.

A brick call in Ultimate frisbee refers to a situation where an offensive player signals and calls "brick" after the pull. This call allows a different offensive player to pick up the disc instead. If there is a disagreement among players regarding whether the pull landed out-of-bounds or in-bounds, the midpoint on the sideline between the two proposed pivot locations should be used.
