Size Guide
How much space do you actually need? That depends on what you’re storing and how well you stack it — but you shouldn’t have to guess. Work through the four steps below for a solid estimate, then check the breakdown to land on your unit before you spend a dollar.Step One - Round Up the Boxables
Start with everything that can live in a box, and note which box sizes you’ll actually use. Most of what people store boxes up smaller than they think.Step Two - List the Big Stuff
Now the things no box will ever hold: furniture, appliances, mattresses, and the awkward-shaped gear that leans against garage walls everywhere.Step Three - Count It All Up
Tally your boxes by size and count every piece of furniture and equipment on the list. Ten minutes with a notepad saves you renting a size too big — or cramming into one too small.Step Four - Match Your List to a Unit
Take your tally to the Size Guide Breakdown below. Each size shows what it compares to and what typically fits, so you can match your list to a unit with confidence.*Unit dimensions are approximate, and availability varies by facility.
Size Guide Breakdown

5' X 5'
Think walk-in closet: 25 square feet of tidy, out-of-your-way space. The 5×5 is the right call for seasonal gear, boxed-up clutter, and everything that’s been quietly eating your garage.
Fits comfortably:
- Seasonal decorations, camping gear, and yard tools
- Boxed business records, tax files, and office overflow
- Off-season clothes and the toys the kids outgrew
- A chair or two, a mini fridge, and other small furniture or appliances
