The designs of indoor and outdoor courts differ significantly in order to optimize their abilities to withstand various environmental conditions. Outdoor courts, for instance, are vented so that rainwater flows through the tiles, thereby creating a slip-resistant and safer playing surface.
Indoor courts, on the other hand, do not have weather-resistant features or materials, like outdoor courts do. Hard plastic, rubber, or wood may be successfully used to manufacture an indoor court floor. Indoor court floors are built as smooth, non-vented surfaces.
