How big is the backboard on a basketball hoop?
The backboard is available in several sizes, depending on the level and space available:
A professional backboard used in halls and for competitions measures 180 cm (72") wide x 105 cm (42") high.
For home training and play, a backboard of 110-130 cm (43-50") is often sufficient.
For children and beginners, there are smaller backboards starting at about 80 cm (31.5") wide.
Larger backboards make it easier to hit the ring from angles, and are therefore an advantage if you are practicing layups, shots close to the basket or three-point shots.
