Ice hockey rink
An ice hockey rink is an ice rink that is specifically designed for ice hockey, a competitive team sport. Alternatively it is used for other sports such as broomball, ringette, rinkball, and rink bandy. It is a rectangle with rounded corners and surrounded by walls approximately 1.22 metres (48 in) high called the boards. There are two standard rink sizes: North American and international.
Rink, a Scots word meaning 'course', was used as the name of a place where another game, curling, was played. Early in its history, ice hockey was played mostly on rinks constructed for curling. The name was retained after hockey-specific facilities were built.
There are two standard sizes for hockey rinks: one used primarily in North America, also known as NHL size, the other used in Europe and international competitions, also known as IIHF or Olympic size.
Internationally, the dimensions of ice hockey rinks follow International Ice Hockey Federation (IIHF) specifications of 60.0 metres (196.9 ft) in length, and 26.0 to 30.0 metres (85.3 to 98.4 ft) in width, with a corner radius of 7.0 to 8.5 metres (23.0 to 27.9 ft).
The goal lines must be 4.0 metres (13.1 ft) from the end boards and 5 centimetres (2.0 in) wide. The blue lines must be 15.0 metres (49.2 ft) (¼ of the total length of the rink) apart and 30 centimetres (11.8 in) wide. The red centre line must be 30 centimetres (11.8 in) wide, and is drawn across centre ice, parallel with the goal lines.
Most North American rinks follow the National Hockey League (NHL) specifications of 200 by 85 feet (61.0 by 25.9 m) with a corner radius of 28 feet (8.5 m). Each goal line is 11 feet (3.4 m) from the end boards. NHL blue lines are 75 feet (22.9 m) from the end boards and 50 feet (15.2 m) apart. The 13.4-foot (4.09 m) difference in width from the international standard represents a significant difference in width-to-length ratio on the ice.[citation needed]
The rink specifications originate from the ice surface of the Victoria Skating Rink in Montreal, constructed in 1862, where the first indoor game was played in 1875. Its ice surface measured 204 by 80 feet (62.2 m × 24.4 m). The curved corners are said to originate from the design of the Montreal Arena, constructed in 1898.
The centre line divides the ice in half crosswise. It is used to judge icing. It is a thick line, and in the NHL must "contain regular interval markings of a uniform distinctive design, which will readily distinguish it from the two blue lines" (i.e. it must not be a solid single colour as the blue lines are). It may also be used to judge two-line pass violations in leagues that use such a rule.
