How do I know what size I need?

Read through our size guide to see the storage units we offer and determine which one is right for you. Choosing the right size unit will ensure that you only pay for the storage you need. We offer a wide range of sizes to accommodate your storage needs, from 5×5, or 25 square feet, to 10×30, or 300 square feet.* You can also contact one of our facility managers—they’re trained to help you out. *Sizes are approximate.

How do I use self storage?

Self storage can be used for many purposes: As an extension of your home and a place to store seldom-used items To store seasonal items such as decorations or sports equipment As a business storage solution to de-clutter your office or store inventory or equipment As a temporary home for your things while you move…and many more! First, make a list of what you want to store, and determine what size storage unit you need. Don’t forget to think about additional amenities like climate control , drive-up access, and convenient gate hours. Book your CubeSmart unit online at no cost or commitment, then go to the facility to complete your reservation. You’ll need to provide identification: a state-issued ID card, driver’s license, passport, or military ID. All that’s left to do is move in your stuff!
