I didn't measure the broken backboard I had on my Spalding basketball base so that's on me but I thought these were pretty standardly sized. The good thing is that it's smaller, therefore less wind resistant and less likely to blow over the weighted base. The bad thing is that my daughter throws bricks and misses the backboard altogether and running down the street after rogue basketballs is getting old.
