10x30 storage unit guide
A 10x30 storage unit — 300 square feet — is one of the largest standard sizes, typically holding the contents of a 4-5 bedroom house. Here's what it fits, what it costs, and who actually needs one this big.
What fits in a 10x30
- A full household's worth of furniture from a 4-5 bedroom home
- Major appliances — refrigerator, washer/dryer, and similar
- Multiple bedroom sets, a full dining set, and living room furniture
- Boxes for an entire household, plus garage or basement overflow items
- Some people use part of this size for a vehicle alongside household goods, though a dedicated vehicle storage option is usually a better fit for that specific need
Typical cost
A 10x30 typically runs $250-$450/month, though pricing varies significantly by location and demand — see our self-storage cost guide for the full size-by-size breakdown.
Who actually needs a 10x30
This size makes sense for a full household in long-term storage — during a home renovation, an extended relocation transition, or downsizing where you're not ready to part with everything. For most interstate moves where storage is only a brief gap between homes, a smaller size or a moving container's built-in storage option may be more cost-effective. See our full size guide to confirm you actually need this size before booking it.
Alternatives to consider before booking a 10x30
Before committing to the largest standard size, consider whether downsizing some belongings ahead of time could drop you to a 10x20 instead — the monthly savings compound over any extended storage period. For a genuine full-household move rather than long-term storage, a moving container that goes directly to your new home may be more cost-effective than storage plus a separate move.
Frequently asked questions
What size home fits in a 10x30 storage unit?
A 10x30 unit (300 sq ft) typically holds the contents of a 4-5 bedroom house, including large furniture and major appliances — one of the largest standard sizes most facilities offer.
Can I fit a car in a 10x30 storage unit?
Some people do store a vehicle alongside household items in a 10x30, but a dedicated vehicle storage unit or covered parking space is usually a better fit if a car is the primary thing being stored — see our vehicle and boat storage guide.
Is a 10x30 unit significantly more expensive than a 10x20?
Yes, meaningfully — expect roughly 30-50% more per month than a 10x20, since cost scales fairly directly with square footage.
Do most facilities have 10x30 units in stock?
Not always — the largest sizes are less common and can have more limited availability than mid-size units. Book ahead if you know you need this size, especially during peak moving season.
