How to Choose the Right Size Self Storage Unit
Start by Making a List
Ask yourself:
- Are you storing boxes, furniture, or appliances?
- Will you need space to walk inside the unit?
- Are you storing items short-term or long-term?
- Do you plan to add more items later?
Making a quick list can help prevent renting too small of a space — or paying for more room than you need.
Common Self Storage Sizes
5x5 Storage Unit
Best for:
- Seasonal decorations
- Small furniture
- Business files
- Personal boxes
- Dorm room items
Ideal for customers needing a little extra space without renting a larger unit.
10x10 Storage Unit
A 10x10 unit is one of the most commonly rented self storage sizes.
Best for:
- Contents of a 1–2 bedroom apartment
- Furniture sets
- Appliances
- Multiple rooms of boxes
This size works well for families between homes or customers downsizing.
10x15 Storage Unit
A 10x15 unit offers additional room for larger homes or business storage.
Best for:
- Large furniture
- Appliances
- Garage items
- Inventory storage
- Contents of a 2–3 bedroom home
If you are unsure whether a 10x10 will be enough, this extra space can make organization much easier.
10x20 Storage Unit
A 10x20 unit is comparable to a one-car garage.
Best for:
- Entire household storage
- Large moves
- Equipment storage
- Business inventory
- Vehicle or motorcycle storage at select locations
This size is ideal for customers needing maximum flexibility.
Tips to Maximize Your Storage Space
No matter what size self storage unit you rent, packing efficiently makes a big difference.
Use Uniform Boxes
Stacking similarly sized boxes helps maximize vertical space and keeps your unit organized.
Store Heavy Items on the Bottom
Place heavier boxes and furniture first to create a stable base.
Leave a Walkway
A small aisle down the center of your unit makes accessing items much easier later.
Disassemble Furniture
Removing table legs and breaking down bed frames saves valuable space.
Label Everything
Clear labels help you quickly find what you need without unpacking the entire unit.
When in Doubt, Go Slightly Bigger
One of the biggest mistakes customers make is renting a unit that is too small. A little extra room often makes loading, organizing, and accessing your belongings much easier.
If you expect to add items over time, choosing the next size up may save you from needing a second unit later.
