Have a 67 inch wide closet, about 3 feet deep, 8 feet high and this shelving system worked great with a few cuts.
My boyfriend who is very handy said it was easy to install, although it did take him a couple of hours. In my small closet I lost the tall hanging section and  considered putting it up in corner of closet perpendicular to the rest, but have so much added space with the shelves etc did not need to.   This organizer is well designed and beautifully made.  Highly recommend.
