The typical dimensions for a full-size backyard court would be 28m long and 15m wide, mirroring professional basketball court dimensions. However, you don’t have to match these specifications strictly.

Typical backyard basketball court dimensions are 60 feet by 90 feet (for reference, a regulation NBA court is 50 feet by 94 feet). If your backyard space is limited — but you don’t want to settle for the ol’ “single hoop in the driveway” setup — you could also choose a half-court basketball court layout, which is 30 feet by 50 feet.

The most important factor to consider when deciding on the size of your backyard basketball court is the size of your yard. The dimensions of a standard basketball court are 94 feet long by 50 feet wide, with a free-throw line 15 feet away from the backboard.

The ideal size for a DIY backyard basketball court is 30 x 30 feet. This offers you ample room to play above the 3-point line. If you prefer having a full court instead, you can make do with 46 x 78 feet.
