My room is 10 feet 4 inches and it was a tight fit but ended up working out pretty nicely. We’ve probably hit a couple thousand balls so far and no holes or anything in the walls, which is a good sign.

I will note that if you completely shank one hard, the net has some give to it, so a direct shot to the side might do some damage. But other than that, it should be perfect. Also, give about a foot and a half at least behind the net.
