How to Choose the Right Storage Unit Size
Still unsure which unit to rent? A little planning can help you make a more informed decision.
1. Make a list of what you’re storing. Write down your larger furniture pieces, appliances, boxes, and other belongings. This gives you a clearer idea of how much space you’ll need.
2. Measure larger items. Beds, sofas, tables, and bookcases can take up more room than expected. Check their dimensions before choosing a unit.
3. Consider how you’ll pack. Disassembling furniture and using uniform box sizes can help you make better use of available space. Stack boxes securely and keep fragile items protected.
4. Think about access. If you’ll need to retrieve items regularly, allow room for a walkway or arrange belongings so frequently used items are easy to reach.
5. Ask for help before renting. Choosing a unit that’s too small can create frustration, while a larger unit than necessary may increase your costs. Our team can help you compare sizes based on what you plan to store.
