Dan, The 120 film doesn't fit even the negative carrier of a 2.1/4X3.1/4 sheet film, both film sizes being different, thinking probably the GG of one format will not fit the other one........ Have to search more, Cheers, Renato

The ground glass is the same for both sheet film & 120 roll film.

Sheet film is 2.25"x 3.25" as Dan said. That is the OUTSIDE edge size, not the image size. Roll film holder mask an image size of 2.25" x 3.25" on 120 film which is wider than sheet film.

That is why they take different negative carriers.

Even so, the same ground glass is used for both types of film and the ground glass size differs by camera brand. You have to get the size that fits your particular camera.
