The bottom shelf is 13 inches between top and bottom. The other two are only 9 inches. I was planning on putting spray bottles and bottles of cleaning supplies on the cart but they only fit on the bottom shelf. That’s a little disappointing. It fits perfectly between my dryer and the closet in my laundry room. It came with suction cups to secure to the wall but I would only put it in a narrow space. It would probably fall over if it was free standing.
