The minimum requirements are track length on 200 meters, radius of inner curve of 15 meters and width of the competition lanes 2 meters. [6] Short track speed skating tracks have a length of 111.111 metres (364.54 ft). The rink is 60 metres (200 ft) long by 30 metres (98 ft) wide, which is the same size as an international-sized ice hockey rink .
