5×15 storage unit size guide
A 5x15 storage unit offers 75 square feet of floor space and about 600 cubic feet of volume. It suits a one-bedroom apartment, including a washer and dryer, or two furnished rooms — but its narrow 5 ft width makes it awkward for wide furniture.

What fits in a 5×15 storage unit?
- A one-bedroom apartment with appliances
- Two furnished bedrooms
- Long items other units cannot take end to end
- Around 100 medium boxes
Stored on its own, a 5×15 storage unit takes roughly 170 medium boxes at 3 cu ft each. In practice furniture takes most of the space and boxes fill what is left.
What does not fit
- Wide furniture — the width limit is the same as a 5x10
- A car
- Anyone who wants to see everything at once: the back 5 ft is effectively sealed

Is a 5×15 storage unit right for your home?
A one-bedroom apartment, or anyone who needs length rather than width — skis, ladders, lumber, long shelving.
| Home size | Estimated volume | Fill rate in this unit | Verdict |
|---|---|---|---|
| storage for studio apartment | 278 cu ft | 55% | Comfortable |
| storage for 1 bedroom apartment | 445 cu ft | 87% | Comfortable |
This is the size where the answer genuinely splits, which is why a room count is not enough. The difference between a minimalist one-bedroom and a well-settled one is around 200 cubic feet — one whole unit size. If that is your situation, the sizing 1 bedroom apartment works through the same decision with the extras that usually push people up a size.
How to pack a 5×15 storage unit
The same unit holds noticeably different amounts depending on how you load it. Three workable layouts:
- Depth-first. Least-needed items in the back third, seasonal in the middle, current in the front third. The only sane way to use a deep, narrow unit.
- Appliances at the door. Washer and dryer just inside the door on a pallet, everything else behind. Appliances are the hardest thing to move twice.
| Packing density | What it means | Usable volume | With a 15% access aisle |
|---|---|---|---|
| Loose | Nothing stacked above head height, fragile items, room to move things around. | 420 cu ft | 357 cu ft |
| Moderate | Stacked to around 7 ft with furniture placed sensibly. The default. | 510 cu ft | 434 cu ft |
| Tight | Stacked to the ceiling, uniform boxes, disassembled furniture. Needs planning. | 558 cu ft | 474 cu ft |
The gap between loose and tight packing in this unit is 120 cubic feet — often a whole unit size. Our packing guide covers how to get to the tight end without burying the things you need.

Limitations of this estimate
Less popular than a 10x10 of similar price, and for good reason: the same volume in a 10 ft wide unit is far easier to use. Take a 5x15 when the price gap is real or a 10x10 is unavailable.
Three things this page cannot know: the actual interior dimensions at your facility (advertised sizes are nominal and real units are often a few inches under), the door and ceiling clearance, and how well you will pack. Measure your largest item and check it against the door width before you sign anything — our measuring guide covers what to record.
How we estimate capacity
Volume is floor area × ceiling height: 5 × 15 × 8 = 600 cu ft. Usable volume applies a packing-efficiency factor — 85% at moderate density — and subtracts a further 15% when you need an access aisle. Item volumes come from our packed volumes for 110+ household items, which uses packed cubic feet, the same basis professional movers use on a cube sheet.
Cost ranges are aggregated from published list prices across major US operators and are reviewed twice a year. Full detail, assumptions and known error margins are on the the full method and its error margins.
