A 5x10 storage unit is 50 square feet and holds about one small bedroom. A 10x10 is 100 square feet, holds a family room or two full bedrooms, and has a much wider door. At AA Personal Storage in Parowan, the 5x10 rents for $40 a month and the 10x10 for $65 (as listed in October 2026). Pick the 5x10 for boxes and a few small pieces. Pick the 10x10 the moment a couch, sectional, or large table is on the list.
Twice the floor space for $25 more a month sounds like an easy call, but it isn't always the right one. If you're storing boxes and a dresser, you'd be paying for empty air. If you're storing a sofa, the 5x10 may not even get it through the door. This guide puts the two sizes side by side with the real numbers from our facility so you can choose once and not have to move twice. If you're weighing every size we offer, our full storage unit size guide covers them all.
Here's how the two units compare at our Parowan facility, straight from our Rent page:

Both units are ground level and drive-up, with asphalt right to the door, month-to-month rentals, and 24/7 access.
Numbers on a screen are hard to picture, so here are some everyday comparisons. They're approximate, but they help.
A 5x10 is 5 feet wide and 10 feet deep. Picture a long walk-in closet, or a bit less than a quarter of a one-car garage. You walk in through the door and the space runs back from there. With a 9-foot ceiling, you can stack boxes well above head height, which is where most of a 5x10's real capacity comes from.
A 10x10 is a square, 10 feet on each side. Think of an empty small bedroom, or a little under half a one-car garage. Because it's square, you can arrange furniture along three walls and still keep a walkway down the middle. That makes it much easier to reach things you'll need before move-out day.
Most size guides talk only about floor space. At our facility, the door width matters just as much.
The 5x10 has a roll-up door 3.7 feet wide (about 44 inches). The 10x10's door is 8.5 feet wide (about 102 inches). Both are 7 feet 10 inches tall.
What that means in practice:
Measure your widest piece before you rent. If anything is wider than about 42 inches and can't be turned or taken apart, skip the 5x10.
Our Rent page says a 5x10 fits "the contents of a small bedroom, including a queen-sized bed, a dresser, a TV, and several small to medium-sized boxes." A typical load looks like this:
It's also a great fit for things that aren't furniture: holiday decorations, camping gear, hunting gear in the off-season, tools, and the boxes that are crowding your garage. Our full "what fits in a 5x10" guide is coming soon.
Need just a little more? We also rent a 5x12.5 for $50 a month (October 2026). It has the same 3.7-foot door but 12.5 square feet more floor space, which is enough for an extra dresser or a dozen more boxes.
Our Rent page says a 10x10 fits "the contents of an entire family room or two full bedrooms, including several small to medium-sized boxes." A typical load:
That's most of a one-bedroom apartment. We cover the 10x10 in much more detail, including packing layouts, in our full 10x10 guide. If you're packing up a one-bedroom place, a dedicated guide on sizing for a 1-bedroom is on the way.
Here's the math with our October 2026 rates:
The 10x10 costs $25 more each month, $300 more over a year. But it gives you twice the space, so the price per square foot actually drops from $0.80 to $0.65. If you'd fill even 70% of a 10x10, it's the better deal.
Two common mistakes cost people more than the rent difference:
On the other hand, if your list is mostly boxes and small items, the 5x10 saves you $300 a year with no downside. Don't rent space you won't use.

Pick the 10x10 if:
Look past both if you're storing a two- or three-bedroom home. Our 10x15 ($75 a month as listed in October 2026) holds about three bedrooms and larger items like a piano.
People in Iron County rent small units for a handful of reasons, and each one points to a different size:
One rule that applies to both sizes: vehicles aren't allowed in enclosed units. If you're storing an RV, boat, trailer, snowmobile, or ATV, our outdoor parking is the place for it. Snowbirds parking a trailer for the season should also read our guide on how to winterize your RV before temperatures drop.
Whichever size you pick, packing smart lets you store more and reach it later:

Most units need your own disc lock, though a few come with a lock and key on the floor. If you use a disc or cylinder lock and add one of our Tenant Protection plans, you avoid the $200 deductible. Plans run from $2,000 to $15,000 in coverage.
A 10x10 is usually the better fit for a one-bedroom apartment. It holds a sofa, a bed, a dresser, a small dining set, and 25 or more boxes, and its 8.5-foot door takes large furniture easily. A 5x10 only works if you're storing just the bedroom or mostly boxes.
At AA Personal Storage, a 5x10 rents for $40 a month and a 10x10 for $65 a month, as listed in October 2026. Both are month to month. A $50 reservation fee holds a unit for 25 days and is credited toward your move-in charges. Check our Rent page for current rates.
Sometimes, but it's tight. Our 5x10 doors are 3.7 feet wide, so a standard sofa has to go in standing on end, and sectionals usually won't fit at all. If a couch is on your list, the 10x10, with its 8.5-foot-wide door, is the safer choice.
