Ice Hockey Rink
There are two standard sizes for hockey rinks: one used primarily in North America (NHL, AHL, ECHL, etc.), the other used in the rest of the world (IIHF). The two sizes are known as NHL (for the smaller version used primarily in North America), and Olympic (for international play).
In a hockey rink, the boards are the sides of the rink. The “side boards” are the boards along the two long sides of the rink. The half boards are the boards halfway between the goal line and blue line. The sections of the rink located behind each goal are called the “end boards.” The boards that are curved (near the ends of the rink) are called the “corner boards.” It is a popular misconception that the half boards are the entire section of boards on the sides of the rink.
