The size of a standard basketball court used in the professional or college ranks measures 94 feet long x 50 feet wide while many high school courts measure 84 feet long x 50 feet wide.  Junior high courts can be even smaller at 74 feet long x 42 feet wide.  Based on this, basketball half court dimensions would be 47 x 50, 42 x 50, or 37 x 42.  However, our research shows that most people installing a backyard basketball court are mostly concerned with getting a court with an entire 3-point arc and don’t necessarily want an entire half court.  Therefore, we have based our basketball half court kits on the most commonly requested sizes.
