The court
How many walls does a squash court have?
Squash (sport)
Basic rules and gameplay. The court. The squash court is a playing surface surrounded by four walls. The court surface contains a front line separating the front and back of the court and a half court line, separating the left and right hand sides of the back portion of the court, creating three 'boxes' - the front half, the back left quarter and the back right quarter. Both the back two boxes contain smaller service boxes. All of the floor-markings on a squash court are only relevant during serves. There are four walls to a squash court. The front wall, on which three parallel lines are marked, has the largest playing surface, whilst the back wall, which typically contains the entrance to the court, has the smallest. The out line runs along the top of the front wall, descending along the side walls to the back wall. There are no other markings on the side or back walls. Shots struck above or touching the out line, on any wall, are out. The bottom line of the front wall marks the top of the 'tin', a half metre-high metal area which if struck means that the ball is out. In this way the tin can be seen as analogous to the net in other racquet sports such as tennis. The middle line of the front wall is the service line and is only relevant during serves.
