I operate seven locations and unfortunately most of these were aquistions so I had no say in the unit mix. For the most part, the unit mix should represent a bell curve. Less small units, a lot of mid size and less large units.

However, I will tell you that you want your average space to be around 150 sq ft. Larger is better in today's market. I spent a lot of money and time converting small spaces into larger ones last year.

Build smart so small spaces and easily be converted in the future. Also, climate control typcially means smaller spaces but do not be afraid to have large spaces, examply 10x20 and 10x30.

We find that 10x20 is our most popular size right now.
