• Global Security Storage has a good variety of storage unit sizes to suit your needs, but sometimes it can be difficult to know exactly what size you actually need. This storage space calculator will help estimate the amount of space you need (and help avoid paying for unnecessary extra space).



• It's a good idea to create a list of what you are going to be putting into your storage unit, and then use that list to fill out the calculator below. Note that the space determined is an estimate, and that extra space may be required for full access to all items, as well as if a lot of the items are not fully stackable.



• If you have an item not on the lists below, find something with a similar size to what you're looking for. After filling in the number of each item, click Calculate and an estimated cubic footage will be determined. You can then click on one of the links to our two locations for a list of sizes that will be compatible with the space you need.
