What is the size of a full-size basketball court?

The NBA and NCAA use a 94 feet by 50 feet size of basketball court, respectively, the complete size of a basketball court as per Basketball Court Size In Feet. Most high schools in the United States also use this standard. International FIBA courts are a little bit shorter, measuring approximately 91.9 feet long. The size 94 by 50 feet makes the game the same regardless of the level of play, whether professional or amateur.
