Basketball court dimensions vary in overall length and width. In many areas of the country, older high school gymnasiums in particular have smaller overall size and layout than regulation. Many of these same gyms have varying backboard designs and dimensions.
Even though College and High School courts may differ on overall size, the interior markings for the “Foul Line”, “The Key”, “The Backboard and Rim” are the same.
Regulation Sizes - Official Measurements:
Court Size Overall:
- College – 94 feet long and 50 feet wide
The Foul Line:
For all courts the “foul line” distance
is 15 feet from the foul line to the front of
the backboard
The Key:
Standard for all basketball courts, “the
key” (sometimes called “the lane”)
is 12 feet wide. Regulation courts have the backboard
extending out 4 feet over the baseline into the
key. A 6 foot arc (half circle) extends from
the foul line away from the basket to complete
the key.
