The information shown above are measurements of the playing surface only for basketball courts. These measurements do not take into account any out of bounds area that may surround the court. Many architects today design the outer perimeter of the court with very little or even no out of bounds area this in our opinion is mistake. The out of bounds areas important because it allows room for bleachers or other spectator seating to be installed. We recommend that if you are designing a new court that you leave it minimum of 6 feet perimeter around the outer edge of the playing surface for out of bounds area. We would rather see 8 to 10 feet or even more if possible however we understand that budget constraints often dictate the available space.

The dimensions listed above also do not take into account non-regulation size courts. The dimensions listed above a typically associated with courts that will have sanctioned play on them. However most gymnasiums will never have sanctioned play such as church gymnasiums, Boys and Girls Club's, YMCAs, parks and rec centers, etc. There is no hard and fast rule of how big the court must be there is however guidelines for the actual main of the court we recommend always using proper lane lines as shown in the diagram layout of court dimensions above. All other dimensions however are subjective and based on your specific needs. We specialize in custom designing courts of all sizes shapes colors and types. We also offer top quality institutional and residential sports equipment for your consideration.
