Though there are smaller and larger storage units at certain locations, the most common sizes are: 5×5, 5×10, 10×10, 10×15, 10×20, 10×25, 10×30.
I'm not sure, I rented smallest a 5x10. You will have to call to see what's best for you and what is available. I had to wait a few days for the smallest size.
Don't really know but you can call them to find out
