Car storage units in Affton, MO, and nearby areas

Q: What size storage unit is best for a car?

A 10’&#215;20’ unit is the go-to size for most standard cars. Compact cars? You might only need a 10’&#215;15’. Trucks, vans, or larger SUVs? A 10’&#215;30’ will give you the extra space you need.

Q: Can two cars fit in a 10&#215;30 storage unit?

Yes – in most cases! A 10’&#215;30’ unit is about the size of a standard two-car garage, so you can usually fit two compact vehicles side by side.

I’m a student and went through the Storage Mall to store my dorm room over the summer. I thought everyone was very nice and it was easy to book over the phone without any hidden price increases or issues. The facility was clean and they gave me simple access instructions to move in on a Sunday when the office wasn’t staffed. Prices after fees were a lot more affordable (especially as a student) compared to college storage companies or public storage!
