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

It's better to have a little extra space than to cram everything in. A slightly larger unit makes it easier to access your items and keeps them in better condition.

Tips for Choosing the Right Size

1

Make an Inventory

List all items you plan to store. Group by size (large furniture, boxes, oddly-shaped items).

2

Consider Access Needs

If you'll access items frequently, leave room for aisles. Stack strategically with frequently-needed items in front.

3

Think Vertically

Our units have high ceilings. Use shelving and stack boxes to maximize vertical space.

4

Plan for the Future

If you might add items later, consider going one size up. It's easier than moving to a larger unit.
