A plain-English guide
Storage container or storage unit?
A 9 × 40 ft storage container gives you 360 square feet — more than a 10 × 30 storage unit and about the size of a two-car garage — with drive-up doors and no shared hallway. At Goose Island Park Storage in Rockport, Texas, a standard container is $125 a month and a climate-controlled container is $150. For a small load, a 5 × 10 or 10 × 10 unit at our sister facility, 188 Self Storage, may be the better fit.

How the sizes compare
Storage units are usually sold by the footprint. A 9 × 40 ft container's 360 square feet compares like this:
- 5 × 10 unit — 50 sq ft: a closet's worth, boxes and a few small pieces
- 10 × 10 unit — 100 sq ft: about one bedroom of furniture
- 10 × 20 unit — 200 sq ft: a one-car garage, two or three rooms
- 9 × 40 container — 360 sq ft: roughly a two-car garage, a whole house of furniture
What fits in a 9 × 40 container
A full household — beds, sofas, dining set, appliances and boxes — or a small business's inventory and equipment. Fishing and hunting guides use them for rods, reels, decoys, coolers and spare motors next to their boat.
When a container makes more sense
If you have more than a room or two, need to drive a truck or trailer right up to the doors, or want a space nobody else shares, a container usually wins. If you just need a few boxes out of the house, a small unit costs less.
