The height of the ceiling must be at least 16 feet when creating an indoor basketball court. With a regulation rim 10 feet above the floor, there must be enough room for the ball to reach the basket without interference from the ceiling.
It’s recommended to strive for a peak ceiling height of 20 feet or more if the construction allows it. To provide the proper visibility needed for play, caged lighting should be located where it is least prone to disruption. It is also a good idea to include high windows for additional natural light. During practise or competition, the higher the ceiling, the fewer interruptions and the need for the shooter to adjust shot attempts.
