Helpful Advice

Tips for Choosing the Right Size

Make an Inventory

List everything you plan to store. This gives you a clearer picture of how much space you actually need.

Go One Size Up if Unsure

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

Stack Smart

Use uniform boxes and stack vertically to make the most of the 8'6" ceiling height. Place heavy items at the bottom.

Leave an Aisle

If you'll need regular access, leave a walkway down the centre so you can reach items at the back easily.
