A squash court is a four-walled indoor space designed specifically for playing the sport of squash. The court measures 32 feet long and 21 feet wide, with a height of at least 15 feet. The front wall features a service line and a tin at the bottom, which players must avoid hitting during play. Players use a squash racket to hit a small rubber ball against the walls, aiming to make it bounce in a way that their opponent cannot return it. The game can be played in singles or doubles, with specific rules governing scoring and serving.
