What Size Storage Unit Do I Need?

For a studio or one-bedroom apartment, a 10×10 unit is usually the right fit. A 10×12 to 10×17 works well for a two-bedroom home, and a 10×20 or larger handles a three-bedroom house or more. RAD Mini Storage offers 13 unit sizes at 611 E 12th St, Imperial, CA from a compact 4×9 up to a 20×24 so you can match your space (and your budget) exactly instead of paying for a room you don’t need.

What Size Do I Need for My Move?

Studio or one-bedroom apartment A 7×9 to 10×10 covers a bed, dresser, a few boxes, and small furniture.If you need less space and are mainly storing boxes, seasonal belongings, or a few smaller items, a 4×9 may be worth considering. See our guide to what you can fit in a 4×9 storage unit before sizing up.

Two-bedroom apartment or small home A 10×12 to 10×17 fits two bedroom sets, a small living room, and 30-50 boxes, with enough floor space to still walk in and reach the back.

Three-bedroom house A 10×20 or 10×24 holds full bedroom sets, a dining table, major appliances (fridge, washer/dryer), and 60-100 boxes.

Four-bedroom house or more A 14×24 to 20×24 is built for a full household move — every room’s furniture, appliances, and overflow boxes, with room to spare.

Rule of thumb: if you’re between two sizes, size up. The cost difference between neighboring sizes is often just $10-20/month, and it’s cheaper than a second trip or paying for a unit you can’t actually access because it’s packed floor-to-ceiling.

Comparing Close Sizes

10×10 vs. 10×12: The 10×12 adds 20 extra square feet for about $10/month more. If you have a one-bedroom apartment plus a few extra boxes or a bike, the 10×12 gives you breathing room the 10×10 won’t.

10×15 vs. 10×17: Both fit a two-bedroom home, but the 10×17’s extra 20 sq ft is the difference between tightly stacking everything and being able to actually walk down the middle to grab something in the back.

10×20 vs. 10×24: The 10×24 is the better choice if you’re storing a full three-bedroom house and larger items like a sectional sofa or a riding mower, since the extra depth gives you a place to put oversized pieces without blocking the door.

14×24 vs. 15×24 vs. 20×24: These are our largest indoor units. The jump from 14×24 to 15×24 is a modest width increase for households with slightly more furniture; the 20×24 is the size to choose if you’re combining a full household move with a vehicle or a large amount of business inventory.

How Much Fits? Packing Tips

• Boxes: as a rough guide, a 10×10 comfortably holds 40-60 medium moving boxes if you’re not storing large furniture alongside them.
• Leave an aisle: don’t stack wall-to-wall. Leaving even a narrow walkway down the middle means you can reach items in the back without unloading the whole unit.
• Go vertical: most of our units have 8-foot ceilings, stack sturdy boxes and use shelving to make use of the height, not just the floor space.
• Disassemble what you can: bed frames, table legs, and shelving units take up far less room broken down than assembled.

FAQs

What size storage unit do I need for a one-bedroom apartment?
Most one-bedroom apartments fit in a 7×9 or 10×10 unit. If you have extra boxes or larger furniture, a 10×12 gives you a bit more room.

What’s the difference between a 10×10 and a 10×12 storage unit?
A 10×12 has 20 more square feet than a 10×10 about the size of an extra closet for roughly $10 more per month. It’s a good step up if a 10×10 feels tight.

How many boxes fit in a 10×10 storage unit?
Around 40-60 medium moving boxes if that’s all you’re storing. Fewer if you’re also storing furniture, since furniture takes up floor space boxes can’t be stacked on.

Will my couch and mattress fit in a 10×15 unit?
Yes. A 10×15 comfortably holds a full bedroom set (mattress, dresser, nightstands) plus a couch, coffee table, and 30-40 boxes.

Can I store a car, RV, or boat in one of these units?
Indoor units up to 20×24 can fit a compact car, but RVs, boats, and trailers are stored outdoors in our dedicated vehicle storage area; see our RV, Boat & Vehicle Storage page for details.

What size storage unit do I need for a full house move?
For a three-bedroom house, most customers choose a 10×20 or 10×24. For four bedrooms or more, our 14×24, 15×24, or 20×24 units give you room for a full household plus appliances.
