The contest area is a flat, non‑slip mat. The contest area can be installed on a platform 0.6m‑1m high from the base.
The colour scheme of the mat’s surface must avoid giving a harsh reflection, or tiring the contestant’s or spectator’s eyesight. The colour scheme is also appropriately matched to the contestant’s equipment, uniform and the surface of the contest area.
There are two shapes used on competition. In both shapes the contest area and safety area are different colours.
This competition area includes the contest area and safety area. The contest area is a 8m x 8m square and a safety area of 2m to 4m. The total size of the competition area which includes the contest area and safety area is 10m x 10m to a maximum of 12m x 12m.
The competition area is a minimum of 10m x 10m to a maximum of 12m x 12m. At the centre of the competition area is an octagonal shaped contest area. The contest area measures 8m in diameter and each side of the octagon is 3.3m long. Between the outer line of the competition area and boundary line of the contest area is the safety area.
