How much self storage space do I need?

Can I change sizes later?
Yes, you can upsize or downsize a unit if you discover that you need more or less space. You can also switch from a standard unit to a climate controlled unit (where available), and vice versa. If you need to switch to a different storage unit, please speak to your facility manager for details.

How should I pack my storage unit?

Start by packing the outer edges of your storage unit first, putting the most frequently used items near the front. This will help you create walkways and keep your most-used belongings close for easy access.

Use your vertical space, placing larger items at the bottom and packing the unit upward to make the most of the height. Large items like couches and mattresses can even be turned on end to use that vertical space. Just be sure to properly protect your furniture so it doesn't get damaged.
