1. The side-wall lines connect the front-wall line and the back-wall line.

2. The service-box is a square formed by the short-line, one side wall and two other lines marked on the floor.

3. The length, width and diagonal of the court are measured at a height of 1000 mm above the floor.

4. It is recommended that the front-wall line, side-wall lines, back- wall line and the top 50mm of the tin be shaped so as to deflect any ball that strikes them.

5. The tin must not project from the front wall by more than 45 mm.

6. It is recommended that the door to the court be in the centre of the back wall.

7. The general configuration of a squash court, its dimensions and its markings are illustrated on the diagram at Appendix 7.2.


A squash court may be constructed from various materials providing they have suitable ball rebound characteristics and are safe for play; however, the WSF publishes a Squash Court Specification which contains recommended standards. A National or Regional Governing Body may require that the WSF standards must be met for competitive play.
