One of the most important things you will need to consider is what size backboard you will need for your new basketball court. Backboard sizes vary in width from 48” wide all the way up to 72”, but for the sake of regular game play we recommend choosing backboard no smaller than 54” wide. Anything narrower than this measurement won’t allow the player to perform bank shots at all!

This “half-size” backboard provides the same consistent ball response and durability as its big brothers, the 72” and 60”, but it is sized to fit the needs of a family with young players just learning the game. Junior systems are adjustable, but from three to five feet only.
