A 15-degree back-slope on a backboard provides a lofted ball return that will land further away from the board compared to the flatter, shorter rebound off a flat wall. Some players and coaches prefer the lofted return because it allows more time to prepare for the shot and places the player further from the practice wall. When considering a back-sloped model, remember that the bottom of the backboard will encroach 30″ into the court compared with the 4″ of intrusion of a flat backboard. Back-sloped models are often placed on the side of a court rather than behind the baseline where run back-space is more critical. Back-sloped backboards are available in the same sizes as Flat backboards.
