Our Self Storage Unit Size Guide

Small Storage Units

  • Our smallest self storage units are also some of our most convenient and affordable. Self-Stor-It lets you rent month by month, so you can store with us for seasonal storage and long-term use. Small storage units are about the size of a walk-in closet; therefore, they do have some sizing restrictions. You will be able to fit a few large boxes and miscellaneous items, but you should use caution when attempting to store larger sized mattresses and pieces of furniture. 

Medium Storage Units

  • This next size category gives you a little more wiggle room. Medium storage units start at 80 square feet and range up to 150 square feet. Think of these as being able to hold about 2-3 rooms’ worth of contents. You might be able to fit a few mattresses, two or three pieces of bedroom or office furniture, and a handful of large boxes.  

Large Storage Units

  • When you rent from our large storage unit category, you have access to up to 200 square feet of storage space. Keep the contents of your home secure during a move, or make Self-Stor-It your long-term nearby storage solution for your business. Our temperature-controlled storage units can protect business inventory, antiques, clothing, and other sensitive materials through any Connecticut season.
