Freedom Self Storage Unit Size Guide

Small Storage Unit

  • This category has your most cost-efficient storage units. Think of them as the size of a walk-in closet that can fit about a room’s worth of items—a few large boxes and miscellaneous items filling the rest of the space. Since our small storage units begin with low dimensions, it is always a good idea to double check the measurements of your items before attempting to store them. For instance, you may be able to fit a twin or full-sized mattress, but you likely need to rent a larger storage unit if you plan to store kings and queens. You can make the most of smaller spaces like this by stacking your items or creating shelving organization.

(Pro Tip: When stacking boxes, make sure your heaviest are at the bottom with lighter ones on top to avoid damage.)

Medium Storage Unit

  • Slightly larger than our smallest options, our medium storage units give you more wiggle room. These can fit about 2-3 rooms’ worth of content and have much fewer sizing restrictions. All mattress sizes should fit inside your medium storage unit, and the largest of the bunch can even fit small vehicles, like ATVs or jet skis. With Freedom Self Storage’s temperature-controlled storage options, our self storage is also convenient for businesses that need to store sensitive materials—inventory, documents, electronics, office equipment, etc. Talk with one of our storage experts to find the right space for your specific storage needs. 

Large Storage Unit

  • Providing the space you need is our specialty, so we also have large storage units with a variety of amenities. Go with indoor storage if you are storing moisture-sensitive items or plan to store long-term. You can also choose drive-up storage to help handle your larger loads with easy unloading. Large storage units also come in handy during a move. You can rest assured your belongings are secure as you settle into your new space. If you are moving to our charming city, check out our mover’s guide to St. Marys, GA, to learn more about the area!
