Official Rules of Racquetball

7.2 - Court Markings

Generally, the markings are the same as the USAR’s standard rules, except that on an outdoor court, there is no receiving (5-foot) line. Since the size of outdoor courts may vary, the exact placement of other lines may also vary. Both side lines and a back line are drawn, as needed, to denote a 20 foot by 40 foot “in-play” area on the surface of the court. Some outdoor courts may also have singles service lines to reduce the server’s advantage. These lines are usually placed 18 inches inside each side line and run from the short line to the back line. These lines are only in force during the serve and are not used for doubles play.
