Which Is Best for You: A 5x5 or 5x10 Storage Unit?
A 5x5 storage unit is best for storing small furniture and boxes and for saving money, while a 5x10 is the best value if you have more or larger items and offers you room to grow. Use these common storage scenarios to find the right size for your needs.
Moving Box Storage (Short-Term Between Apartments):
5x5: If you're between apartments with just a 1-2 week gap and no furniture, a 5x5 unit can hold 20-25 medium moving boxes for short-term storage. This works when your new place is furnished, or you're buying new furniture.
5x10: Upgrade to a 5x10 if you're also storing any furniture or have specialty items (bikes, sports equipment, musical instruments, etc.) that don't fit efficiently in boxes.
Seasonal Business Inventory:
5x5: Small retail operations storing 20-25 medium boxes of products, displays, or equipment can work within a 5x5 footprint when items stack efficiently.
5x10: Upgrade to a 5x10 if your inventory includes larger displays or equipment, you’re storing more than 25 standard boxes, you need aisle space to access items frequently, or your business is actively growing.
Dorm Room or Small Bedroom Storage:
5x5: A 5x5 works if you’re storing the contents of a single dorm room or a single bedroom, including a twin or full mattress, dresser, and boxes of belongings.
5x10: Upgrade to a 5x10 if you have a full bedroom set with nightstands, multiple dressers, a large bed frame, or bulky items like a futon or couch.
Decluttering or Renovating:
5x5: A 5x5 unit can hold boxes from one room while you complete home improvements or spring cleaning.
5x10: Upgrade to a 5x10 if you also need to store furniture or you’re renovating or decluttering multiple rooms.
How to Choose the Right Size Unit
Tips for Choosing:
Take Inventory: List all items you plan to store.
Measure Your Items: Note dimensions of everything in your inventory, especially different box sizes and appliances or furniture.
Test the Space: Map out different layouts with painter’s tape on your floor to see if items will fit.
Remember to Stack: Most storage units are around 8 feet tall, so remember to account for vertical space.
Keep Pathways Open: When mapping, make sure to plan for paths throughout your unit so you can access belongings.
Size Up if Unsure: It’s a better choice to size up in advance if you’re not sure everything will fit—otherwise you run the risk of running out of room on move-in day.
Additional Considerations:
Accessibility: If you need to access items in your unit often, you’ll want more room for larger paths through the unit.
Climate Control: If you have temperature-sensitive items, you may need climate-controlled, heated, or air-cooled storage.
Drive-up Access: If any of your items are difficult to move, consider renting a unit with drive-up access to make loading and unloading easier.
