The height of the platforms – , and – gives the diver enough time to perform the acrobatic movements of a particular dive. There are additional platforms set at and . Diving platforms for FINA sanctioned meets must be at least long and wide. Most platforms are covered by some sort of matting or non -slip surface to prevent athletes from slipping. All three levels of the platform are used in the NCAA competition. Each level offers a distinct degree of difficulty (DD) and therefore could yield different scores for divers. Ten-meter diving. Diving began in the Olympics in 1904 for men, in what was called "fancy diving", which has been believed variously to have been off a platform or off a springboard. The 10-meter dive began in the 1908 Olympics. Diving for women started in the 1912 Olympics, with the 10-meter dive. In 2016, dives performed by competitors in 10-meter  world competition included a 3-½ somersault tuck, a 3-½ somersault pike, a 2-½ somersault with 2½ twist, a forward 4-½ somersault, and a forward reverse 3½ somersault.
