There are ansi standards for 4x5, 5x7, 8x10, probably 11x14 and maybe a few
others (probably 2x3 and 3x4). However, the banquet sizes were never
standardized. Each camera maker made film holders of their own design and
specifications or used particular holders made by someone else. Some
builders make different cameras to fit holders from different sources so
even "the same" cameras would require different holders to work correctly.
If you want to build a camera to take some odd size, you probably want to
find a source of holders (or design and build your own) before building the
back. Make sure any holders you buy have the same dimensions.

I can provide these numbers for 4x5, 5x7, 8x10 and 11x14. Give me a little
bit and I'll do that this evening. While we are at it, why not setup the
table for the whole gamut? Say 2X5, 5x7, 4X10, 7X17, 8x10, 11X14, 14x17,
12X20, 16X20 and 20x24.
I think a table of rear box sizes would be helpful. In my research, it seems
that most rear boxes are 13% to 17% larger that the film size. An example
would be 12 inch rear for an 8X10 in film.
