Q:

What is the basketball backboard's dimensions?

A:

A National Basketball Association regulation backboard measures 72 inches horizontally and 42 inches vertically. Official NBA rules also stipulate that the backboard must be flat and transparent.

The backboard must be marked with a white rectangle centered behind the hoop. The rectangle must measure 2 inches in width, 24 inches horizontally and 18 inches vertically. The backboard must be positioned so that the hoop attached to the board is exactly 10 feet above the ground. The basketball rim measures 18 inches in diameter. The material used to create the backboard has varied greatly since the sport's inception in the 1890s, when wooden backboards were used. Most major basketball leagues now use Plexiglas backboards.

  • Q:

    What are proper basketball court dimensions?

    A:

    According to the National Basketball Association, basketball courts should be rectangular shapes that are 94 feet long and 50 feet wide, with inner dimensions including a 23 foot, 9-inch semicircular three-point arc at either end of the court; however, dimensions for other leagues and age groups may differ. For example, middle and high school courts are typically smaller than regulation NBA size, although the NCAA, or college league, and WNBA, or women's pro league, use the same court dimensions as the NBA. In all of the above-mentioned courts, the free throw line is situated exactly 15 feet away from the point on the floor that corresponds with the hoop's backboard location.
