I have a brand-new empty closet to start with, It measures 12 foot deep by 6 foot. I used three of the 4-8ft kits covering both long walls. I did not put anything on the back wall I left that open for a full length mirror.This gave me plenty of shelves and hanging area. I even used a small rod for jewelry. I also bought a couple of shoe rack brackets to use with some shelves and a belt organizer that works wonderful.
