Storage Unit Size Guide: What Size Storage Unit Do I Need?
Choosing the right storage unit can be difficult when you're trying to picture how much space your belongings will actually take up. Our self storage unit size guide makes it easier to compare your options and find a unit that fits what you need to store.
Storage Kings offers a wide range of storage sizes—from smaller climate-controlled units for household belongings to extra-large spaces for boats, RVs, vehicles, trailers, equipment, business inventory, and more.
Because available sizes and storage types vary between our Fargo, North Bismarck, and South Bismarck locations, use this guide as a starting point and check current availability before reserving.
Storage Unit Size Calculator
Not sure where to start? Use our interactive storage calculator to estimate the amount of space you may need. Enter the items you're planning to store, and the calculator can help point you toward an appropriate unit size.
The calculator is a helpful starting point, but not every storage need fits neatly into a traditional size. If you're storing a vehicle, boat, RV, trailer, business equipment, or another large item, our team can also help you compare its dimensions with available units.

Storage Unit Size Chart
Storage Kings offers a much wider range of sizes than traditional small, medium, and large storage options. Here's a simple way to start comparing the amount of space you may need.
| Unit Size | Approx. Space | A Good Starting Point For |
|---|---|---|
| 5x10 | 50 sq. ft. | Boxes, seasonal items, small furniture, contents of a small room |
| 10x10 | 100 sq. ft. | Furniture, appliances, boxes, smaller apartment storage |
| 10x15 | 150 sq. ft. | Larger apartment storage, furniture from multiple rooms |
| 10x20 | 200 sq. ft. | Household moves, furniture, some vehicles depending on dimensions |
| 10x25–10x30 | 250–300 sq. ft. | Larger household storage, business inventory, equipment |
| 12x20–14x30 | 240–420 sq. ft. | Vehicles, trailers, equipment, business or household storage |
| 14x40–14x50 | 560–700 sq. ft. | Boats, RVs, campers, trailers, vehicles and equipment |
| 18x50–24x50 | 900–1,200 sq. ft. | Large RVs, boats, trailers, vehicles, equipment and business storage |
| 30x50–50x50 | 1,500–2,500 sq. ft. | Shop Condo space, business inventory, equipment, vehicles and larger storage needs |
These examples are general guidelines. Actual fit depends on the dimensions and arrangement of your belongings, vehicle, trailer, RV, or equipment.
What Size Storage Unit Do I Need for a 1-Bedroom Apartment?
For many one-bedroom apartments, a 5x10 or 10x10 storage unit can be a good place to start. The right size depends on how much furniture you have, the size of your belongings, and how efficiently everything can be packed.
A 5x10 may work well if you're primarily storing boxes, a mattress, smaller furniture, and seasonal belongings. If you're storing most of the contents of a fully furnished one-bedroom apartment, a 10x10 may give you more flexibility.
Storage Kings offers different sizes and storage types depending on location, including climate-controlled options for belongings that benefit from a more consistent storage environment.
What Size Storage Unit Do I Need for a 2-Bedroom Apartment?
A 10x10 or 10x15 storage unit is often a good starting point for a two-bedroom apartment, depending on the amount and size of your furniture.
A 10x10 may work for a more lightly furnished apartment, while a 10x15 provides additional room for larger furniture, mattresses, appliances, boxes, and other household belongings.
If you'll need to access your belongings while they're in storage, consider leaving a small aisle through the unit. That little bit of extra room can make a big difference when you need something stored toward the back.
What Size Storage Unit Do I Need for a 3-Bedroom House?
A three-bedroom home can require considerably more space depending on furniture, appliances, garage contents, outdoor equipment, and how much of the household you're storing.
A 10x20, 10x25, 10x30, or larger unit may be appropriate depending on your situation. Storage Kings also offers significantly larger drive-up units at select locations if a traditional storage unit isn't enough.
If you're storing an entire household during a move, renovation, or transition, talk with our team before reserving. We can help you compare what you're storing with the actual units currently available.
Typical and Standard Storage Unit Sizes
There isn't one storage unit size that works for everyone. Traditional self storage often centers around familiar sizes such as 5x10, 10x10, 10x15, and 10x20, but Storage Kings offers options well beyond those standard dimensions.
That's especially helpful if you're storing something larger than household belongings. Depending on the location and availability, Storage Kings has spaces for vehicles, boats, RVs, campers, trailers, contractor equipment, business inventory, and other large storage needs.
We also offer different types of storage. Depending on the property, options may include climate-controlled storage, standard drive-up storage, heated storage, drive-through units, Shop Condos, and outdoor parking.
Available Storage Unit Sizes at Storage Kings
Because our inventory differs by location, finding the right unit isn't just about choosing a dimension. You'll also want to consider where the unit is located, what you're storing, and what type of storage you need.
