Because most gymnasiums accommodate a basketball court, they are usually around 110 feet long and 60 feet wide. The regulation size of a high school basketball court is 84 feet long and 50 feet wide.
High school gymnasiums that house a basketball team must always reach somewhere over 84 feet long by 50 feet wide in order to fit the regulation size basketball court. Since many community gyms also house basketball courts for recreational use, they have similar dimensions. Many gymnasiums around the 84 feet by 50 feet measurement choose to divide their space for smaller cross court basketball courts or volleyball courts.Gymnasiums that have multiple basketball courts or other sports facilities can be even larger.
