When Is a 5x15 Storage Unit the Right Choice?
Here are common scenarios where a 5x15 unit makes perfect sense:
-
Youre moving out of a one-bedroom apartment.
-
Youre staging a home and need to temporarily store furniture.
-
Youre remodeling part of your house.
-
You have seasonal items or business inventory.
If youre between leases or waiting to close on a home, this size gives you a comfortable middle ground not too small, not too large.
Tips for Choosing the Right Unit Size
1. Make an Inventory List
Write down everything you plan to store including furniture, boxes, appliances, and odd-shaped items. Use this to visualize the space required.
2. Use Online Space Calculators
Many storage providers offer online tools that help estimate the right unit size based on your inventory. While not perfect, theyre a helpful starting point.
3. Visit the Facility in Person
Ask to see an empty unit in person. Standing inside can help you judge if the 5x15 space is suitable for your belongings. It also gives you a chance to check lighting, accessibility, and security features.
4. Consider Vertical Space
Stacking is your friend. If your furniture or boxes can be safely stacked, you might need less floor space than you think. This is especially true in a unit like the 5x15, where vertical room can dramatically increase your usable space.
5. Think About Access Needs
If you need to access items regularly, go slightly larger than you think. Its better to leave room for a narrow aisle than have to unload half the unit to reach the back.
Other Factors to Consider
-
Climate Control: If youre storing wooden furniture, electronics, books, or delicate items, climate control protects against extreme temperatures and humidity.
-
Security: Look for gated access, security cameras, and on-site management.
-
Convenience: Choose a location near your new home to minimize travel during your move.

Choosing the right storage unit size can save you time, money, and frustration during a move.
