The men's ball's circumference ranges between 29.48 and 30 inches
(749 and 762 mm); its diameter 9.3 to 9.5 inches (238 to 242
mm). It weighs 1.246 to 1.374 pounds (567 to 624 g). The women's
ball's circumference is between 28.50 and 29.01 in (724 and 737
mm), its diameter 9.07 to 9.23 inches, and its mass from 1.123
to 1.246 pounds (510 to 567 g).
The Basketball Court
A regulation basketball court in international games is 28 by 15
meters (approx. 92 by 49 feet) and in the NBA is 94 by 50 feet
(approx. 29 by 15 meters). Most courts are made of wood, and
have various markings,
2 inches (5 centimeters) wide to mark off the various sections.
The Basket and Backboard
A basket and backboard hang over each end of the court. The basket
consists of a cast-iron rim and a net, and is connected by supports
to the backboard.
The backboard sits 10 feet (NBA), which is the
same as 3.05 meters (FIBA), above the court and four feet inside
may have either a fan shape or rectangular shape. The fan shaped
backboard is 54 inches (140 centimeters) wide, and has the "target
area" at the bottom center. The rectangular backboard is 72
inches (180 centimeters) wide and has its "target area" in
the lower center. Both "target areas" are 24 inches long
and 18 inches wide.
Basketball Game Attire
For both mens' and womens' teams, a standard uniform consists of
a pair of shorts and a sleeveless tank top. Players also wear
high-top sneakers that provide extra ankle support. Years ago,
female players' unforms consisted of short-sleeved shirts and
skirts. This type of uniform has long since been phased out.
At all levels of competitive basketball, the basketball uniforms
have the team's name printed across the upper chest area, plus
a number. The numbers help identify a player to fans and - more
importantly - other players, coaches and game officials. The
uniforms of the home team are often white (or some other light
color), while the visiting team wears a darker-colored uniform.
International games mandate the numbers from 4 to 15. At the high
school and college levels, numbers generally range from 1-5, 10-15,
20-25, 30-35, 40-45, and 50-55, plus 0 and 00. Colleges usually
have no restrictions on which numbers are used, although in some
states, high school teams must wear even-numbered jerseys if they're
the home team and odd-numbered jerseys if they're considered the
visitor. Also, teams may have either 0 or 00, but not both. Uniform
numbers in the NBA are generally the same, although many players
have worn numbers above 55 (e.g., Dennis Rodman, who wore No. 91
while playing with the Chicago Bulls).
Of course, fans don't have to spend money to buy suitable clothing
to play basketball. Sometimes, all that's needed is a pair of sneakers,
a pair of loose-fitting shorts and perhaps a T-shirt or tank top
(although male players sometimes play bare-chested).
