According to someone on the amazon comment section, internally it is 14" H, 10 5/8" W, and 11 3/4" D. That seems about right. It's not huge, but for my purposes it is about right. I can go 2 sticks deep in my drawers easily, 3 if they are smaller RG. I could have done deeper drawers and that would fit more, but I wanted the drawers to be able to act like shelves or drawers.
