Quick Planning Tips Before You Choose
Before diving into specific sizes, here are a few quick steps to help you estimate your storage needs:
Create an inventory list – Write down everything you plan to store, from furniture and appliances to boxes and oddly-shaped items
Estimate box count – If you’re packing boxes, try loading them in your car first to visualize how much space they’ll occupy
Consider access needs – Do you need room to walk through your unit, or can items be packed tightly?
Think long-term – Will your storage needs grow over time? Factor in potential additions
Measure large items – Know the dimensions of furniture, appliances, and vehicles you’re storing
Pro Tip: Many customers underestimate how much space boxes take up. A good rule of thumb: 10-15 medium moving boxes fill approximately 10 square feet of floor space.
