Some of the most common questions on racquetball discussion groups include “What is the rule for this situation?” and “Where can the rules be found?”.
Examining the rules for the correct terminology will almost always get you to the answer for the rule for the situation as well.
One of the important concerns in international discussion groups (Reddit Racquetball [5.5k members], FB World Racquetball News [3.2k members], FB Racquetball Friends [8.5k members]), is to be clear about which rules set your situation describes. For example, the LPRT uses a different rules set than the International Racquetball Tour which uses a different rules set than USA Racquetball which uses a different rules set than the International Racquetball Federation. All of these groups use a standard 40x20x20 court, and only the IRF calls the back wall out above 12 feet in every environment.
Portions of the rest of the English-speaking world play racketball or racquetball on a squash court. This uses another completely different rules set and it changes if you are in England/Scotland/South Africa or if you are in Australia.
Links to as many of these rules sets as possible are linked below. Some of the organizations use a subset/superset of another organization’s rules, i.e. the IRT uses most of USA Racquetball’s rules, changes a few, and adds or clarifies a few. Their rules are included as an appendix in the USAR document.
