Rules
The UFC cage is an octagonal structure with walls of metal chain-link fence coated with black vinyl. The standard octagon has a diameter of 30 ft (9.1 m) with a 6 ft (1.8 m) high fence. The cage sits atop a platform, raising it 4 ft (1.2 m) from the ground. It has foam padding around the top of the fence and between each of the eight sections. It also has two entry-exit gates opposite each other. The mat, painted with sponsorship logos and art, is replaced for each event.
