Finding Your Fit: What Storage Unit Size Do You Need in Smithfield, Utah?

Choosing a unit is easier when you start with what you're actually storing instead of trying to guess from square footage. A few pieces of furniture need a very different setup from the contents of a home, a trailer, or equipment with extra height. At our Smithfield property, the available drive-up units range from 10x10 through 12x40, so there's a meaningful difference between the smallest and largest enclosed spaces available here. You can review current storage options in Smithfield as you compare the sizes below.

Start With What You Need to Store

Before settling on dimensions, make an inventory. Count the furniture, appliances, boxes, outdoor equipment, and other pieces that won't pack neatly into a standard box. Then think about whether you'll need to retrieve anything while it's stored, because a unit packed completely from front to back leaves little room to reach items at the rear.

Our storage size guide recommends this same basic approach: list what can go into boxes, identify furniture and awkwardly shaped items, estimate quantities, and then compare that inventory with available dimensions. It takes a little more work than choosing based only on the number of rooms in your home, but it gives you a better estimate.

10x10 Storage Units

A 10x10 gives you 100 square feet of floor space. In our general size guide, we compare this size to about half of a standard garage and use the contents of a one-bedroom home as a useful reference point. Sofas, tables, dressers, mattress sets, bicycles, office furniture, and packed boxes are among the items that can fit, depending on their dimensions and how they're arranged.

At our Smithfield facility, 10x10 is the smallest enclosed unit size currently listed. Every unit is at ground level with drive-up access, so you can pull your vehicle to the unit door instead of carrying furniture through a building. That setup is particularly useful when you're moving bulky pieces or making several trips to unload boxes.

10x15 Storage Units

Moving up to a 10x15 gives you 150 square feet. Our size guide uses the belongings of a two-bedroom home as a general reference and lists larger household furniture, bedroom sets, appliances, outdoor gear, and office furnishings among the common uses for this size.

The extra five feet of depth matters when a 10x10 would require you to stack too aggressively or block access to things you'll need later. If you're storing for several months, leaving a usable route through the unit may be worth choosing a little more room. Our packing and storage tips recommend keeping frequently needed items near the front and leaving a walkway when you'll be returning during the rental period.

10x20 Storage Units

A 10x20 provides 200 square feet. In our general guide, we compare this size to a small garage and present it as an option for the contents of a three- or four-bedroom home. Large furniture, appliances, mattresses, outdoor equipment, office furnishings, and a substantial number of boxes can fit when the space is planned carefully.

This size is also worth considering when storage is part of a move or renovation. Instead of packing every available square foot, you can organize the unit so that boxes and furniture you expect to retrieve first aren't trapped at the back. Labeling boxes on more than one side also makes them easier to identify once they're stacked.

Larger 12-Foot-Wide Units

Our Smithfield property goes beyond the standard 10-foot-wide sizes. Current options include 12x20, 12x25, 12x30, 12x35, and 12x40 units. The 12x30, 12x35, and 12x40 spaces have 14-foot clearances intended to accommodate taller loads, including trailers and equipment.

These larger spaces aren't simply substitutes for a crowded household unit. Their dimensions make them relevant when the item itself drives the decision, especially with equipment or vehicles that require more length, width, or height. Measure the full dimensions of anything large before choosing a space rather than assuming that a particular vehicle or trailer will fit.

Don't Forget About Outdoor Parking

Not everything needs an enclosed unit. Our Smithfield property also has outdoor parking from 12x15 through 12x40 for RVs, boats, trailers, cars, trucks, and motorcycles. Pull-through 12x30 and 12x40 parking spaces are also listed, which can simplify entry and exit with longer vehicles or trailers. Measure the entire vehicle before choosing parking, including anything that extends beyond the main body. For a boat, that may include the trailer tongue and motor. For an RV or trailer, account for hitches, ladders, spare tires, or other permanently mounted equipment.

Think About Access Before Filling the Unit

Our Smithfield property sits at 405 W 4600 N on the north end of Smithfield, just off US-91. Every listed unit is ground-level and drive-up, and the property is fenced and gated with security cameras. Current access hours are listed as seven days a week from 4:30 a.m. to midnight.

Drive-up access makes loading straightforward, but how you arrange the space still matters. Put heavier boxes at the bottom of stacks, protect furniture with sheets, moving blankets, or breathable covers, and keep items you'll need again near the door. A simple inventory on your phone can save you from opening half a dozen boxes later.

Choose Space Based on the Load, Not a Guess

Room-count comparisons are useful starting points, but furniture dimensions, box quantities, equipment, and the amount of access you want inside the unit matter more. Make an inventory first, measure the largest pieces, and leave enough room to use the space the way you intend.
