The only films I can recall that had edge-masks in the latter 20th century were the 126, 110 and dic formats from Kodak, the Instimatic, Pocket-instamatic and the Disc cameras.
For both 135 and 120, the frame size can be from quite small to the length of the roll.
For instance, in shooting 35mm film through my X-Pan, I had the choice of both 24x36mm and 24x66mm on the same roll. On my different 120 cameras, I had the choice of 6x4.5cm, 6x6cm, 6x7cm, 6x8cm, 6x9cm, 6x12cm depending upon the camera I used. That gave me anywhere from 16 frames/roll to 6 frames.
Some of the panorama cameras like the Fuji/Linhoff cameras would use even 6x17, about 4 shots per roll. Going to something like a Hulcherama you would get one shot and that wasn't for a full rotation. You almost need to run 70mm film for those specialized tools to use them well.
As long as the film (and most roll film is this way) doesn't have pre-exposed frame edges, frame length is dictated by your camera/back combo and in most cases, the back or camera will have some designation somewhere on it or in the instructions what that frame size actually is.
