A squash court is a rectangular box with four vertical walls of varying height. These walls are known as the front wall, side walls and back wall. The front wall line, side wall line, back wall line and upper 50mm of the tin are shaped to deflect any ball that strikes them.
The court has a level floor and a clear height above the court area.
The length, width and diagonal of the court are measured at a height of 10cm above the floor.
Squash courts are also used for racquetball.
