120 Roll film was invented by Kodak in the late 1890's You should look at the formats most of those old folders which took 120 film..2 1/4 x 3 1/4 on 120 size was quite common. I can point to a few examples the Kodak Autographic and early Folding Brownies between 1919-1929, the actual image size is ~56mm x ~84mm, (with some incidental variation), which reduces nicely down to 2x3 or 6x9.
