Section 2: Equipment
2.1 The Ball (WSF Rules of Squash, Rule 2)
The ball used in official play must conform to WSF specifications and carry WSF approval. The ball is hollow and made of rubber compound.
- Diameter: 40.0–44.0 mm (1.57–1.73 inches)
- Weight: 23.0–25.0 grams (0.81–0.88 ounces)
- Stiffness: 3.2–4.5 kg at 20°C (68°F)
- Seam type: The ball may be seamless or have a seam, provided all other specifications are met
Balls are colour-coded by dot to indicate speed/bounce characteristics. The double yellow dot (extra slow) is the standard ball used in professional and elite competition. The single yellow dot (slow) is used in cooler courts or at recreational level. Orange and red dot balls are faster and used by beginners.
A ball must be replaced if it breaks during play. Either player may request a ball change if the ball becomes damaged or excessively worn. The Referee determines whether a change is warranted.
2.2 The Racket (WSF Rules of Squash, Rule 1)
Rackets must comply with WSF specifications. Only WSF-approved rackets may be used in sanctioned competition.
- Maximum overall length: 686 mm (27.0 inches)
- Maximum overall width: 215 mm (8.46 inches)
- Maximum strung area: 500 cm² (77.5 sq inches)
- Frame material: Any material, provided all other specifications are met
- Strings: Must be uniform; strings may not be arranged to provide extra catching or throwing effect. No attached objects may affect the flight of the ball
The frame and strings must be of uniform colour or combination of colours. A player whose racket is found to be non-compliant during a match may be required to change rackets. Failure to do so constitutes Conduct.
2.3 Player Attire
Players must wear appropriate squash attire. In WSF-sanctioned events, players must wear predominantly white or light-coloured clothing on glass show courts unless a special colour exception is granted by the event organisers. Footwear must be non-marking and suitable for squash court surfaces. Eye protection is mandatory in doubles and strongly recommended for all players at all levels.
