How high is a basketball hoop?
The top of the hoop is 10 feet (305 cm) above the ground. Regulation backboards are 72 inches (183 cm) wide by 42 inches (110 cm) tall. All basketball rims (hoops) are 18 inches (46 cm) in diameter. The inner rectangle on the backboard is 24 inches (61 cm) wide by 18 inches (46 cm) tall.
In professional and most higher college settings, the backboard is part of a portable stanchion that can be moved out of the way in other sports, though in most high schools and examples such as Stanford University’s Maples Pavilion, backboards are mounted as part of a suspended system using ceiling joists to support the goal and allow them to be put out of the way in the ceiling when not in use.
The first glass backboard was used by the Indiana Hoosiers men’s basketball team at the Men’s Gymnasium at Indiana University.After the first few games at their new facility in 1917, spectators complained that they could not see the game because of opaque wooden backboards. As a result the Nurre Mirror Plate Company in Bloomington was employed to create new backboards that contained 1 1⁄2-inch-thick (3.8 cm) plate glass so that fans could see games without an obstructed view. It was the first facility in the country to use glass backboards.
Professional glass backboards used to break from 625 pounds (283 kg) of force or more. Modern professional and higher-level college play backboards do not have the glass absorbing any weight to avoid breaking.
