What fits in a 10×30 storage unit?
- A four to five-bedroom house with garage contents
- An RV, boat or two small vehicles at some facilities
- Commercial inventory on racking with an access aisle
- Around 480 medium boxes stored alone
Stored on its own, a 10×30 storage unit takes roughly 680 medium boxes at 3 cu ft each. In practice furniture takes most of the space and boxes fill what is left. For a room-by-room breakdown with layout diagrams, see what fits in a 10×30 storage unit.
What does not fit
- Anything under four bedrooms — you are paying for air
- RV storage without checking first: many facilities cap vehicle length or ban them outright

Is a 10×30 storage unit right for your home?
A large house in full, a business holding stock, or an RV owner with a facility that allows it.
| Home size | Estimated volume | Fill rate in this unit | Verdict |
|---|---|---|---|
| sizing studio apartment | 278 cu ft | 14% | Comfortable |
| sizing 1 bedroom apartment | 445 cu ft | 22% | Comfortable |
| what 2 bedroom apartment needs | 630 cu ft | 31% | Comfortable |
| sizing 3 bedroom house | 1,168 cu ft | 57% | Comfortable |
| what 4 bedroom house needs | 1,632 cu ft | 80% | Comfortable |
At this size the question shifts from "which unit" to "one unit or two". Two 10x15s often cost less than one 10x30 and give you two doors, which matters if you will be retrieving things. If that is your situation, the what 4 bedroom house needs works through the same decision with the extras that usually push people up a size.
How to pack a 10×30 storage unit
The same unit holds noticeably different amounts depending on how you load it. Three workable layouts:
- Two zones. Front half for anything you may need, back half sealed. At 30 ft deep, treating it as one space is how things get lost for a year.
- Vehicle plus household. Vehicle in the front half for drive-out access, household goods stacked in the back half. Reverse this and you cannot move the car.
| 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. | 1,680 cu ft | 1,428 cu ft |
| Moderate | Stacked to around 7 ft with furniture placed sensibly. The default. | 2,040 cu ft | 1,734 cu ft |
| Tight | Stacked to the ceiling, uniform boxes, disassembled furniture. Needs planning. | 2,232 cu ft | 1,897 cu ft |
The gap between loose and tight packing in this unit is 480 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
Two 10x15 units often cost less than one 10x30 and give you two doors. The larger unit wins when you need a single long space — a vehicle, racking, or oversized items.
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: 10 × 30 × 8 = 2,400 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 furniture dimension dataset, 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 assumptions behind this figure.
