Squash rackets and balls.

The rule book and where the specifications sit

The current rule book is the World Squash Singles Rules 2025, effective 1 September 2025 after updates at the World Squash Federation's Extraordinary General Meeting on 14 June 2025. The previous edition, the Rules of Singles Squash 2024, took effect on 1 January 2024. The WSF announced a rebrand to "World Squash" (a new name and logo) on 28 January 2025, as The Squash Site reported, and its website has moved from worldsquash.org to worldsquash.sport.

Rule 1.1 says the court, ball and racket must meet WSF specifications, which it places in Appendix 5 (Technical Specifications). Appendix 5 does not print numbers. It says the specifications are set and agreed by the WSF Courts and Equipment Commission and published on the WSF website as separate pages for court construction, ball specifications and racket dimensions.

The 2025 edition renumbered its appendices. Protective eyewear moved from Appendix 6 in 2024 to Appendix 4 in 2025, and technical specifications from Appendix 7 to Appendix 5. One cross-reference was missed: the 2025 Appendix 6 (Coaching, Player Analysis Technology) still says equipment must conform to "Appendix 7", the 2024 number. Appendix 6 also allows player analysis technology to be built into playing equipment that meets the specifications; it may record or store information during a match, but a player may not retrieve it during the match.

Rackets

The WSF racket-dimension page could not be read. A search-result extract of the WSF rules site says the WSF regards products made outside its official specifications as against the interests of the sport; that page returned an error, so the wording is unconfirmed. No WSF racket approval list was recorded for this site.

The rule book itself mentions the racket in play in two places:

• Rule 5.1: the player who wins the spin of a racket serves first.
• Rule 12.2.1 (Fallen Object): a player who drops the racket may pick it up and play on, unless the ball touches the racket, a distraction occurs or the referee applies a conduct penalty.

Balls

Rule 11 (The Ball) covers what happens to the ball during a match, as the 2025 rules state it:

• A ball that breaks during a rally means a let for that rally.
• A player who stops play claiming the ball is broken, when it is not, loses the rally.
• The ball is changed if both players agree, or if the referee agrees with one player.
• There is no let for an unusual bounce.
• After a ball change or a delay, the players may warm the ball up again, and play resumes when both agree or at the referee's discretion.

Search results name a WSF "Approved Balls" page, but it redirected to the new World Squash site and was not read, so whether and how the WSF lists balls is unconfirmed here.

The dot system, as the PSA explains it

Squash Canada reproduces the Professional Squash Association's explanation of ball dots. It describes the slower balls by how much longer they "hang" than the double yellow ball.

These percentages are the PSA's descriptions, not a World Squash specification.

Of the five sports, squash is the only one whose world body's rules, as read for this site, make eye protection mandatory in some events: World Squash's Appendix 4 and the national rules are on eye protection standards. Non-marking shoes are on court shoes, and the court specification on court surfaces and pace. No US CPSC, Health Canada or EU Safety Gate recall of a squash racket or ball was found in web searches made on 26 October 2026; see recalls. Squash 57 (formerly racketball), a related game under World Squash, is not covered on this site.
