Notes
- The Side Wall line is inclined between the Front Wall Line and the Back Wall Line.
- The Service Box is a square delineated by the Short Line, the Side Wall, and two additional lines marked on the floor.
- Measurements for the length, width, and diagonal of the court are taken at a height of 1000mm above the floor.
- It is advisable to shape the Front Wall Line, Side Wall Line, Back Wall Line, and the upper 50mm of the Tin to redirect any ball striking them.
- The upper section of the Tin must not extend more than 45mm from the Front Wall.
- It is suggested that the court door is positioned at the center of the Back Wall.
- The clear height may gradually decrease to 5000mm from a point 1000mm away from the front wall and further reduce to 4000mm from a point 3000mm away from the back wall.
North American vs International Squash Courts
North American Squash Courts are typically 2 feet narrower than International Courts. This was done during a time when low temperatures made it difficult to warm up a single or double dot squash ball, so a hard ball was used instead.
As the hard ball is bouncier and faster, players found it more manageable to play in narrower courts. However, as central heating systems came mainstream, it the soft ball became more playable and International size courts are preferred by more players and clubs.
Today, the hard ball squash court is more than 3 feet wider than the international court.
