Our Storage Unit Size Guide

Small Storage Units

  • In terms of your home, our small ­storage units stand at about the size of a walk-in closet. These ideally fit the content from an average-sized bedroom. You can fit a few pieces of larger furniture, such as desks and mattresses, and some small- or medium-sized boxes. Many people use small storage units when they need to clear some extra space in their garages, closets, attics, and sheds. These will comfortably fit your lawn mower, and golf clubs in colder weather. In warmer weather, your small storage unit can house holiday decorations and other seasonal pieces. We will keep your artificial tree in tip-top shape until you are ready to sing Christmas carols and bust out the ornaments.

Medium Storage Units

  • If small storage units hold one bedroom’s worth of items, medium storage units can hold two or three bedrooms’ worth. Now, you can include some bigger furniture, like kitchen appliances, a washer and dryer, and a sofa. If you are moving out of an apartment or condo, a medium storage unit will work well for you. Also, business owners can use self storage commercially, storing inventory and equipment. It’s cheaper than renting other spaces, and you only have to pay for the size you need.

Large Storage Units

  • You would rent a large storage unit if you are planning to move houses and need a place to keep your valuables and big items until you settle in. Our largest sizes can store the mattresses and bed frames from all your bedrooms, patio furniture, outdoor equipment, and all the other boxes you need to fit in as well. They are large enough to fit any extra vehicles or small boats you may have. This will keep your prized possessions in tact until the weather allows you to enjoy them again.
