Input (English): passage: Most North American rinks follow the National Hockey League (NHL) specifications of 200 feet (61 m) × 85 feet (26 m) with a corner radius of 28 feet (8.5 m). The distance from the end boards to the nearest goal line is 11 feet (3.4 m). The NHL attacking zones are expanded, with blue lines 64 feet (20 m) from the goal line and 50 feet (15 m) apart. Canadian rinks may vary from NHL ones, especially in the goal crease shape (semi-circular), and in the rink dimensions which can accept widths from 85 to 100 feet.
