for high school (jumior) 10 and a half feet (this does not address the question)
The dimensions for a rounded basketball backboard in the NCAA is only slightly different than the dimensions for a rounded basketball backboard in the NBA. NCAA regulations allow the basketball backboard to be 4 feet high,Êwhile the NBA requires that the basketball backboard be no more than 3 1/2 feet high.
6" . A STANDARD RECTANGULAR BACKBOARD IS 42" HIGH. THE TOP OF RIM IS 36" FROM THE TOP OF BACKBOARD, SO THAT LEAVES 6" FROM THE BOTTOM OF BACKBOARD TO TOP OF RIM.
It depends but most are 11 feet high.
9'9'' ft or 9'10''!
The hoops are the same height as a normal basketball hoop is.
24" Across 18" High ------------------- I I I I ------------------ Box lines are 2" wide
A NBA regulation backboard is 72" wide x 42" high
The standard basketball backboard measures 1/2 inch thick by 42 inches high by 72 inches wide. In the National Basketball Association (NBA), their backboards include a rectangle in the center that measures 1.5 feet high and 2 feet wide.
There are 15 ft from the free throw line to the backboard.
Free throw line from basketball rim is 15 feet. The rim is twice the size of a basketball measuring across. A basketball is 9 - 9 1/2 inches long. So that means that the free throw line from the backboard is 16 feet 6 inches, or 16 feet 7 inches.
Throughout middle school, high school, college and professional basketball, the backboards are the same size. They are also the same distance off of the floor at 10 feet.
The regulation height of a basketball backboard is 10 feet off the ground. So unless you're playing on a kiddie hoop or a carnival game, you better start practicing your hops if you want to make those dunks!
