Understanding the Space
When you rent a 5x10 storage unit is a standard self‑storage space measuring 5 feet wide by 10 feet deep, with a typical ceiling height of 8‑9 feet, you’re getting about 400 cubic feet of usable volume. The floor area is 50 square feet, roughly the size of a small bedroom. Because most units are empty‑wall, you can fill the height with shelves or stack boxes, but you must keep aisles wide enough for a trolley or hand truck.

Common Household Items That Fit
Below is a practical list of items most people store in a 5x10 unit. Numbers are averages based on typical dimensions.
- Boxes: 30-40 medium moving boxes (18"×18"×16")
- Mattresses: 2 twin or 1 queen‑size mattress
- Clothing: 4-5 wardrobe boxes or 3‑4 garment racks
- Bicycles: 2-3 standard road bikes (or 1‑2 mountain bikes with helmets)
- Seasonal décor: 1‑2 holiday décor boxes, 1 set of outdoor cushions
Furniture That Can Be Stashed
Furniture takes up the bulk of the space. Here’s what fits without crowding.
- Sofa: A 3‑seat couch (≈ 80"L×35"W×35"H) plus a coffee table.
- Bedroom set: One queen‑size bed frame, 2 nightstands, and a dresser (≈ 150sqft total).
- Dining set: A 4‑person table with 4 chairs (≈ 60"L×36"W×30"H).
- Bookshelves: 2-3 standard 3‑shelf units (≈ 30"W×12"D×72"H each).
Tip: Disassemble bed frames, table legs, and larger shelves to shave off 5‑10 inches per piece, letting you fit more.
Appliances and Large Gear
Big appliances are doable if you prioritize them over extra boxes.
- Washing machine+dryer stack (≈ 27"W×27"D×70"H each).
- Small refrigerator (≈ 30"W×30"D×70"H).
- Portable air conditioner (≈ 20"W×20"D×48"H).
- Outdoor grill or patio set (≈ 40"W×30"D×40"H).
Never store gasoline‑powered generators or flammable chemicals in a standard unit; opt for climate‑controlled or hazardous‑material‑approved spaces.

Packing and Layout Tips
- Measure first: Sketch the unit on graph paper, marking doors and any support beams.
- Place the largest items against the back wall, leaving a 2‑foot aisle for a hand truck.
- Use uniform‑size boxes so they stack neatly; label each side with contents.
- Height‑stack with sturdy pallets or metal shelving to protect the floor.
- Cover furniture with moving blankets to avoid dust and scratches.
- Seal boxes with packing tape and place heavier boxes at the bottom.
When you follow a systematic layout, you often squeeze an extra 5‑10% more items into the same space.
How a 5x10 Stacks Up Against Other Sizes
Unit Size | Floor Area (sqft) | Typical Capacity (cubicft) | What It Holds |
---|---|---|---|
5x5 | 25 | ≈ 200 | 1‑2 bedroom boxes, small mattress, a single chair |
5x10 | 50 | ≈ 400 | 2‑3 bedroom set, 30‑40 boxes, small appliances |
10x10 | 100 | ≈ 800 | Full 3‑bedroom household, large appliances, garage‑type items |
If you’re still on the fence, picture a standard studio apartment - that’s roughly what a 5x10 can contain when packed efficiently.
Frequently Asked Questions
Can I store a queen‑size mattress in a 5x10 unit?
Yes. A queen mattress (≈ 80"×60"×12") fits comfortably along the back wall, leaving room for a nightstand or a few boxes.
Should I choose climate‑controlled storage for furniture?
If you plan to store wood, leather, or fabric items for more than a few months, climate‑controlled units protect against humidity and temperature swings that cause warping or mildew.
How high can I stack boxes safely?
Generally, 4‑5 medium boxes stacked on a sturdy pallet is safe. Use the unit’s ceiling height as a hard limit; a 8‑foot ceiling allows about 4.5 layers of 16‑inch boxes.
Is it okay to store a bike without a cover?
It’s better to use a bike cover or a simple tarp. Dust and moisture can rust the chain and damage the paint over time.
What’s the best way to unload a 5x10 unit when I’m ready?
Start with the heaviest items near the door, then work your way outward. Use a hand truck for boxes and a dolly for furniture legs to avoid back injuries.
Whether you’re downsizing, decluttering, or in the middle of a move, a 5x10 storage unit offers enough room for most two‑person households when you plan the layout wisely. Measure, disassemble, and stack smartly, and you’ll make the most of every cubic foot.
