Hockey Rink
The inline hockey rink is an inline rink which is rectangular with rounded corners and surrounded by a wall, usually called the "boards". Its recommended size measures 80 feet (24 m) wide by 180 feet (55 m) long in the PIHA, while the minimum size for a rink measures 65 feet (20 m) wide by 165 feet (50 m) long. The center line divides the floor in half lengthwise. This divides the floor into zones. Near each end of the rink, there is a thin red goal line spanning the width of the floor. It is used to judge goals.
