The field of play consists of a 64 by 37 m rectangle called the playing field, with an 18 m by 37 m rectangle called an endzone aligned along each of the 37 m sides. See figure 4.1.
The playing field may have any surface, although well trimmed grass is suggested, which is essentially flat, free of obstructions and holes, and affords reasonable player safety.
Goal lines are lines which separate the playing field proper from the endzones and are part of the playing field proper.
Perimeter lines (sidelines and endlines) are lines separating the playing field from the out-of-bounds area and are not part of the playing field.
The corners of the playing field proper and the endzones are marked by cones made of a brightly colored, flexible material.
A restraining line shall be established 5 m from the playing field to ensure that the sidelines remain clear during play.
All lines shall be marked with a non-caustic material and shall be between 5 cm and 10 cm wide.
