How big is a regulation size basketball backboard?
So, how big is a
regulation-sized basketball backboard?
The dimension requirements
listed by the NBA, NCAA and High School are all the same. The regulation size
for a basketball backboard is 42" tall x 72" wide. However, a
48" tall backboard is also permissible.
What about lower levels
The rules governing the size of
a backboard are not as stringent at the high school level. Variable dimensions
are permitted if they are approved by the local governing body.
The regulation backboard is
marked with a white rectangle 2 inches wide that is centered behind the ring;
the outer dimensions of the rectangle are 24 inches wide by 18 inches high. The
basket itself consists of a metal ring with an 18-inch inner diameter and a
white cord net that is 15 to 18 inches long.
