Self Storage Size Guide


The below sizing guide will help you get a better idea of how much space you need. In general, we recommend 25 square feet of storage for every room of furniture you'd like to store. Don't worry if you can't choose between two similar sizes—just rent the space online that you think works best, and if you need another size, we'll adjust your reservation with no problem! Need help? Our friendly staff is available to answer any questions you might have. We can even hold your name on the size you need so you know your unit is waiting for you!
