measures 200 feet by 85 feet. The corners are rounded. The rink is surrounded by a white wooden wall -- the boards -- that stands 40 to 48 inches high. A red goal line extends across each end of the rink, 10 feet from the boards. A goal cage stands in the middle of each goal line. Two blue lines divide the area between the goal lines into two 60-foot end zones and a center zone, which is also 60 feet long. The end zone that a team defends is that team's defending zone; the opposite end zone is the team's attacking zone. The center zone is called the neutral zone. Colored face-off spots mark the places on the ice where officials hold face-offs. Most hockey rinks also have a players' bench for each team and a penalty box, where players must stay temporarily if they break the rules.
