Court Specifications and Terms

Rule 2.1 Court Specifications
The specifications for the standard four-wall racquetball court are:
(a) Dimensions. The dimensions shall be 20 feet wide, 40 feet long and 20 feet high, with a back wall at least 12 feet
high. All surfaces shall be in play, with the exception of any gallery opening, surfaces designated as out-of-play for a valid
reason (such as being of a very different material or not in alignment with the back wall), and designated court hinders.
(b) Markings. Racquetball courts shall be marked with lines 1 1/2 inches wide as follows:
1.  Short Line. The back edge of the short line is midway between, and is parallel with, the front and back walls.
2.  Service Line. The front edge of the service line is parallel with, and 5 feet in front of, the back edge of the short
line.
3.  Service Zone. The service zone is the 5-foot x 20-foot area bounded by the bottom edges of the side walls and
by the outer edges of the short line and the service line.
4.  Service Boxes. The service boxes, used in doubles play, are located at each end of the service zone and are
designated by lines parallel with the side walls [see 4.2(b)]. The edge of the line nearest to the center of the court
shall be 18 inches from the nearest side wall.
5.  Drive Serve Lines. The drive serve lines, which form the drive serve zones, are parallel with the side wall and are
within the service zone. For each line, the edge of the line nearest to the center of the court shall be 3 feet from
the nearest side wall.
6.  Receiving Line. The receiving line is a broken line parallel to the short line. The back edge of the receiving line is
five feet from the back edge of the short line. The receiving line begins with a line 21 inches long that extends
from each side wall. These lines are connected by an alternate series of six-inch spaces and six-inch lines. This
will result in a line composed of 17 six-inch spaces, 16 six-inch lines, and 2 twenty-one-inch lines.
7.  Safety Zone. The safety zone is the 5-foot x 20-foot area bounded by the bottom edges of the side walls and by
the back edges of the short line and the receiving line. The zone is observed only during the serve. See Rules
3.10(i) and 3.11(a).
