Boxes are the flexible part. Alone, a 10×20 storage unit takes about 453 medium boxes; alongside furniture, budget roughly a third of that.
Three ways to lay it out
- Garage-style. Vehicle down the middle, shelving and boxes along both walls, workbench at the back. The layout the unit was designed for.
- Whole house, two aisles. Three blocks of storage with two narrow aisles. Sacrifices about 20% of volume and makes a year-long rental workable.
| Packing density | Usable volume | With a 15% aisle | Medium boxes |
|---|---|---|---|
| Loose | 1,120 cu ft | 952 cu ft | 373 |
| Moderate | 1,360 cu ft | 1,156 cu ft | 453 |
| Tight | 1,488 cu ft | 1,265 cu ft | 496 |
Choosing "tight" is a real decision, not a free upgrade: it means disassembled furniture, uniform boxes and no access until you empty the unit. How to pack a storage unit covers the sequence.
What does not fit in a 10×20 storage unit
- Two cars
- A five-bedroom house with a workshop — look at a 10x30
Check the door width before storing a vehicle: an 8 ft door and a wide truck is a tight, mirror-folding manoeuvre. Also confirm the facility permits vehicles — many require proof of registration and insurance.
What you must not store, at any size
Every US facility bans these by contract, and most leases let them terminate you on the spot:
- Flammables, fuel, propane, fireworks and ammunition
- Anything perishable — food, plants, opened liquids
- Living things, including pets
- Hazardous chemicals, paint, pesticides, asbestos
- Stolen or illegal goods
- Tyres, in many facilities, because of disposal cost
- Anyone living in the unit, which is prohibited everywhere
Drain fuel from mowers and generators before they go in. This is the single most common cause of a lease being cancelled.
If it does not fit
Two honest options, in order of cost.
- Pack tighter. Disassembling bed frames and tables recovers 15–20% of their volume. Uniform box sizes stack far better than mixed ones.
- Size up. A 10×25 storage unit adds 400 cu ft for roughly $35–$60 more a month.
