The shape of the 35mm frame wasn't created, it was happenstance. It just happened to be what you got if you used two 18x24mm motion picture frames together.
Ignoring single frame cameras like the Olympus Pens, cameras using 35mm wide film were reinvented several times. Kodak came out with the Bantam using size 828 roll film, itty bitty paper backed rolls of film making 28 x 40mm images. In the early 1960's Kodak took another stab at it, this time putting both feed and take-up spools in the same plastic cartridge. Kodak's 126 Instamatic film made 28mm square negatives. Then Kodak followed up with the 110 Pocket Instamatic using a 16mm film miniature of the 126 cartridge. They went back to rectangular negatives of about 12 x 17mm, almost the same format as our standard 35mm frames.
