30x40 cm film almost fit in my filmholders. I have to cut 7 mm in length and width. It takes a little extra time to trim the film before loading, but I have managed. It made me wonder if there are any places that sell film in special sizes. I would not mind ordering a considerable amount of film. I have my preferences of make and type, but would be willing to use other in order to save the time cutting my own film.
