As far as I know they have any size you could want. I had a 5 by 10 but then was told by our mover that we would need a 10 by 10. That is what we got and it's costing us $104 a month. All of their sizes and prices along with their specials are posted on their website. You definitely need to check it out.
10x10, 10x13, 10x15, 10x20, 10x30, 10x40, 10x5, 15x20, 20x10, 20x20, 20x30, 5x10, 5x5, 5x7, 7x10, 7x12, 8x10, 8x12
