What neigborhood doesn't need a
basketball court? They all need one! Well once you buy your pole and
backboard and you put it up, how do you go about marking the
court?
Even if you are only putting in a small court, you
would always want to mark your free throw line and 3 point line.
Court Dimensions
An NBA court is 94 ft long
and 50 ft wide.
A College or High School court is 84 ft long and
50 ft wide.
A Junior High court is 74 ft long and 42 ft wide.
Half court is well.. half the distance of the full court.. (I
know, I didn't need to add that)
The free throw line is always 15 ft from the line to the
backboard
The distance from the ground to the rim is 10 ft.
The 3 point arc in the NBA is 22ft to the center of the rim on
the sides ( the arc starts 5 ft 3 in from the baseline, being a
straight line until that point) then the curved part of the arc is
23ft. 9 in. from the center of the rim.
The 3 point arc in college and high school is 19 ft 9 in. (The
straight part extends 63 in out from the baseline before the arc
begins).
The key is 12 feet wide (the width of the free throw line) the
backboard should extend 4 feet out over the baseline. The 12 ft wide
free throw line forms the center of a circle with a 6 ft radius.
The backboard is 72 inches wide by 42 inches high and has an 18
inch diameter rim.
The inner square is marked above the rim in a
rectangle of 24 inches wide and 18 inches high.
