APPENDIX 5.1
DESCRIPTION AND DIMENSIONS OF A SINGLES COURT

DESCRIPTION
A Squash Court is a rectangular box with four vertical walls of varying height; being the Front Wall, Side Walls and Back Wall. It has a level floor and a clear height above the court area.

DIMENSIONS
Length of court between playing surfaces 9750 mm
Width of court between playing surfaces 6400 mm
Diagonal 11665 mm
Height above floor to lower edge of Front Wall Line 4570 mm
Height above floor to lower edge of Back Wall Line 2130 mm
Height above floor to lower edge of Service Line on Front Wall 1780 mm
Height above floor to upper edge of Board 480 mm
Distance to nearest edge of Short Line from Back Wall 4260 mm
Internal dimensions of Service Boxes 1600 mm
Width of all lines and the Board 50 mm
Minimum clear height above the floor of the court 5640 mm

NOTES

1. The Side Wall Line is angled between the Front Wall Line and the Back Wall Line.

2. The Service Box is a square formed by the Short Line, the 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 Line, Back Wall Line and Board are shaped so as to deflect any ball that strikes them.

5. The Board shall not project from the Front Wall by more than 45 mm.

6. It is recommended that the door to the court is 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.

CONSTRUCTION
A Squash Court may be constructed from a number of 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. The standards must be met for competitive play as required by the appropriate National Governing Body of Squash.

APPENDIX 5.2
SPECIFICATIONS OF A STANDARD YELLOW DOT SQUASH BALL

The following specification is the standard for a yellow dot ball to be used under the Rules of Squash.

NOTES

1. The full procedure for testing balls to the above specification is available from the WSF. The WSF will arrange for testing of balls under standard procedures if requested.

2. No specifications are set for faster or slower speeds of ball, which may be used by players of greater or lesser ability or in court conditions which are hotter or colder than those used to determine the yellow dot specification. Where faster speeds of ball are produced they may vary from the diameter and weight in the above specification of a standard yellow dot squash ball. It is recommended that balls bear a permanent colour code or marking to indicate their speed or category of usage. It is also recommended that balls for beginners and improvers conform generally to the rebound resilience figures below.

Rebound resilience @ 45 degrees C 36% to 38%

Improver Rebound resilience @ 23 degrees C not less than 15%

Rebound resilience @ 45 degrees C 33% to 36%

Specifications for balls currently fulfilling these requirements can be obtained from the WSF on request

The speed of balls may also be indicated as follows

3. Yellow dot balls which are used at World Championships or at similar standards of play must meet the above specifications but additional subjective testing will be carried out by the WSF with players of the identified standard to determine the suitability of the nominated ball for Championship usage. The slowest speed of balls intended for elite players and Championship usage may if required be identified by a double yellow dot. Such balls will be deemed for the purposes of this specification to be yellow dot squash balls.

4. From 1 May 2001, yellow dot balls of a larger diameter than 40.0mm specified above, but which otherwise meet the specification, may be authorised for use in tournaments by the official organising body.

APPENDIX 5.3 - DIMENSIONS OF A SQUASH RACKET

DIMENSIONS

Maximum width, measured at right angles to the shaft 215 mm

Maximum length of strings 390 mm

Maximum strung area 500 sq. cm

Minimum width of any frame or any structural member (measured in plane of strings) 7 mm

Maximum depth of any frame or other structural member (measured at right angles to plane of strings) 26 mm

Minimum radius of outside curvature of frame at any point 50 mm

Minimum radius of curvature of any edge of frame or other structural member 2 mm

WEIGHT

CONSTRUCTION

b) Strings and string ends must be recessed within the racket head or, in cases where such recessing is impractical because of racket material, or design, must be protected by a securely attached bumper strip.

c) The bumper strip must be made of a flexible material which cannot crease into sharp edges following abrasive contact with the floor or walls.

d) The bumper strip shall be of a white, colourless or unpigmented material. Where for cosmetic reasons a manufacturer chooses to use a coloured bumper strip, then the manufacturer shall demonstrate to the satisfaction of the WSF that this does not leave a coloured deposit on the walls or floor of the court after contact.

e) The frame of the racket shall be of a colour and/or material which will not mark the walls or floor following an impact in normal play.

f) Strings shall be gut, nylon or a substitute material, provided metal is not used.

g) Only two layers of strings shall be allowed and these shall be alternately interlaced or bonded where they cross and the string pattern shall be generally uniform and form a single plane over the racket head.

h) Any grommets, string spacers or other devices attached to any part of the racket shall be used solely to limit or prevent wear and tear or vibration and be reasonable in size and placement for such purpose. They shall not be attached to any part of the strings within the hitting area (defined as the area formed by overlapping strings).

i) There shall be no unstrung areas within the racket construction such that will allow the passage of a sphere greater than 50mm in diameter.

j) The total racket construction including the head shall be symmetrical about the centre of the racket in a line drawn vertically through the head and shaft and when viewed face on.

k) All changes to the racket specification will be subject to a notice period of two years before coming into force.

The World Squash Federation shall rule on the question of whether any racket or prototype complies with the above specifications, or is otherwise approved or not approved for play and will issue guidelines to assist in the interpretation of the above.
