Mens College (NCAA) Basketball Court Dimension Diagrams

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

Court Size Overall:
- Mens 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 Key:
Standard for all basketball courts, “the

is 12 feet wide. Regulation courts have the backboard

key. A 6 foot arc (half circle) extends from
the foul line away from the basket to complete
the key.
