Our Self Storage Unit Size Guide

Small Storage Unit

  • The smallest category of storage units is great for short-term solutions, like seasonal storage or moving help. At about the size of a walk-in closet, you do have some sizing restrictions, so always be sure to double-check that your items will fit in the storage dimensions. Tackle holiday decoration organization, spring cleaning with this cost-efficient storage option. 

Medium Storage Unit

  • Medium storage units are helpful when you need to store about 2-3 rooms’ worth of items. These can hold large pieces of furniture and even small vehicles, like bikes and jet skis. If you are moving from an apartment or condo and need to stow away your belongings for the time being, this in-between will be a comfortable fit.

Large Storage Unit

  • You may want one of the largest storage options available from Rent-a-Space if you are making a big move or expanding a business. Large storage units should be able to fit most of your possessions, including multiple furniture sets and king-sized mattresses. If you are a business owner, a large storage unit can be your solution for organizing your office or shop space. Focus on creating a clutter-free space for you and your clients to do business.
