The basketball court consists of a rectangular floor with baskets at each end, usually made of wood and highly polished. It measures 94 by 50 feet in the NBA and slightly smaller under FIBA rules. The court also includes markings for the free throw lane, three-point line, sidelines, baselines, center jump circle, and division line. The standard basket consists of a backboard and rim that holds the net and is positioned 10 feet high.

3. the basketball court is the playing surface, consisting of a
rectangular floor, with baskets at each end. In professional
or organized basketball, especially when played indoors, it
is usually made out of a wood, often maple, and highly
polished and completed with a 10 foot rim.

4. Basketball courts come in different sizes. In
the National Basketball Association (NBA), the court is
94 by 50 feet (28.7 by 15.2 m). Under International
Basketball Federation (FIBA) rules, the court is slightly
smaller, measuring 28 by 15 meters (91.9 by 49.2 ft). In
amateur basketball, court sizes vary widely.

7. Free Throw Lane
The free throw lane is a rectangle in a team's front court and used to
line up players during a free throw. The standard free throw lane is
19 feet long by 12 feet wide. The player shooting the free throw
stands at the top of the lane, while other players stand in marked
spots along each side of the lane. On offense, players may not stand
in the lane for more than three seconds unless they are making a
move to the basket with the ball. In the NBA, defensive players may
not be in the lane for more than three seconds unless they are
actively guarding an offensive player. The free throw lane is
sometimes referred to as the “paint” or the “key.”

9. Three-Point Line
The three-point line is a semicircle that surrounds the basket
area on each team's side of the court. Players who stand behind
the line and make a field goal are given three points instead of
the standard two points for a regular field goal. In high school
and women's college basketball, the three-point line is 19 feet 9
inches from the center of the basketball hoop. In men's college
basketball, the line is 20 feet 9 inches away. In the NBA, it
stands 23 feet 9 inches from the hoop at the top of the arc and
22 feet at the sidelines.

11. Sidelines and Baselines
The sidelines and baselines of a basketball court mark the
outside boundaries for out-of-bounds purposes. The sidelines
run the length of the court and the baselines are behind each
basket. All standard basketball courts measure 50 feet in
width. For high school, the court length is 84 feet, while in
college and the NBA it is 94 feet long.

13. Center Jump Circle
The center jump circle is where the game action starts and has a
radius of 6 feet. All players other than the two jumpers must stand
outside the circle until the ball is tipped. The center jump circle is
not used at any other point in the game other than the opening tip
and if a tip is needed to start an overtime period. Two jump circles
located at the free throw line are used in the NBA for held ball
situations.

15. Division Line
The division line is a line running the width of the middle court
that divides it into two equal sections. In high school and college,
a team has 10 seconds to get the ball across the division line,
also known as the halfcourt line. In the NBA, the time
requirement is eight seconds.

17. Basket
The basket -- one on each end of the floor -- is made up of a
backboard and a ring that holds a net, which is designed to
check the ball as it passes through the basket. The standard
basketball backboard is 72 inches wide and is positioned 4 feet
inside the baseline. The hoop, or ring, stands 10 feet off the
floor and is 18 inches in diameter.

20. The official size of the basketball used by the NBA is 29.5
inches in circumference. That's the same size used
throughout men's college and high
school basketball leagues. The WNBA uses a slightly
smaller ball, measuring 28.5 inches in circumference.

23. A backboard is a piece of basketball equipment. It is a raised
vertical board with an attached basket consisting of a net
suspended from a hoop. It is made of a flat, rigid piece of, often
Plexiglas or tempered glass which also has the properties of
safety glass when accidentally shattered.
