I have a copy of the ANSI standards for film holders. It is ANSI PHE.108-1988 and is a revision of ANSI PH#.26-1951. The formats covered are 2X3, 3X4, 4X5, 5X7, 8X10, 11X14 and 14X17.
There never were any ANSI standards for formats such as 6.5X8.5, 5X12, 7X11, 7X17, 8X20, 12X20, 16X20 and 20X24. The closest you can come to standards for these formats is that of the manufacturer, say Eastman, Korona or F&S. However, there are no absolutes, and if you were to acquire randomly ten 7X17" Korona holders chances are good that no two of them would have the exact same dimensions.
