Storage Unit Size Guide
Not sure what size storage unit you need? Use our guide to find the perfect fit for your belongings, whether you're storing apartment contents or a large RV.
Pro Tip: When in Doubt, Go Bigger

Tips for Choosing the Right Size
Make an Inventory
List all items you plan to store. Group by size (large furniture, boxes, oddly-shaped items).
Consider Access Needs
If you'll access items frequently, leave room for aisles. Stack strategically with frequently-needed items in front.
Think Vertically
Our units have high ceilings. Use shelving and stack boxes to maximize vertical space.
Plan for the Future
If you might add items later, consider going one size up. It's easier than moving to a larger unit.
