You can load any size quilt on it. You have to buy the 2x2's to make it the length you want. But then you'll need a table to support all that length & weight not to mention to strength to push it around while quilting. I think it is a good thing for smaller quilts--maybe up to full size. It solves the problem of basting and constantly adjusting the "puddle" under the needle and it is much more portable/storable than a normal machine quilting frame.
I considered it before buying my first setup but I was all ready having trouble with my neck & shoulders and knew it wasn't going to help that problem. I still love to watch him use it at the quilt shows however.
