Query: Good sander but wastes sandpaper

I like the feel of this sander and want to use it for finish work. It is advertised as a 1/3 sheet sander, meaning you should be cross-able to cut three pieces 9" long from a 9 x 11 stock sheet of sandpaper.The sandpaper isn't long enough. I even have some sheets from Norton that are 9-1/8"+ long and they walk off the sander.So to use this thing I have to cut the paper from the length wise direction and so I only get 2 pieces of paper I can use.Effectively it wastes 1/3 of your sandpaper.
