They are only 13.5″ deep though the desk is 20.5″ deep, there is a gap of at least 4 inches between the back of the drawer and cabinet back. Another 2 inches and I could fit a normal sized drawer organizer. Also, the drawers don’t pull out all the way, about 1/3 of the drawer is still inside and hard to utilize (see photo).
