Hello,

I am interested in getting in to ULF Panoramic photography eventually. I am looking at the 12x20 format. I know film for the Ultra Large Formats must be special ordered once a year.

My question is: if one orders say, 8x20 or 12x20 film from the once a year Ilford special run, are the exact film's dimensions standardized throughout the industry?

Ie, if I order 12x20 film, will it fit perfectly into 12x20 Chamonix Film Holders as does 4x5 and 8x10 sheet film fits perfectly the current respective Toyo and Fidelity Holders?
