Tips for Estimating Your Storage Needs
1. Make an Inventory
List everything you plan to store. Our calculator above helps you do this room by room for accurate results.
2. Size Up, Not Down
When in doubt, choose one size larger. This allows walking room and space for items you might add later.
3. Consider Access
If you'll need to access items frequently, factor in aisle space. A slightly larger unit provides convenience.
4. Stack Smart
Plan to stack boxes and lighter items. Utilizing vertical space can help you fit more in a smaller unit.
