When you move out, downsize your home or go traveling for a while, you almost always need to find a storage unit to keep some or all of your things in until you figure things out or settle down. The question is how much space do you need?
5x5 is like a small walk in closet.
5x10 is more like a large walk in closet.
10x10 is the size of a standard one car garage.
10x15 is larger than a one car garage and can hold the entire contents of a three bedroom apartment or home.
10x20 is almost the size of a two car garage.
10x30 is about the size of a one and a half car garage and fits the contents of a 4 or 5 bedroom home.
