Storage space even smaller than traditional mini storage can be found in storage lockers, which start at 3x3.

You might have heard the term “mini storage” before and wondered what the difference between mini storage and self-storage is. To put it simply, mini storage units and lockers are self-storage units on the smaller end of the size spectrum, often ranging from 5x5 to 5x10 feet with a shorter ceiling height. Storage facilities that offer mini storage solutions provide affordable, basic storage for personal items, seasonal goods, and valuables that take up a smaller space.
