It totally depends on the size of the driveway. Basketball hoops come in sizes between 44 inches to 72 inches. If your drive is just for one car, then I would recommend to go for 44 to 48 inches. On the other hand, if the driveway is for two cars then ideally a 54 inches backboard would be perfect. 72 inches backboard hoop is usually for institutes and park courts, but if the driveway is bigger than usual size then it wouldn't be an issue installing it.
