The ANSI standard for the depth of a standard 4 x 5 inch film holder is 0.197" plus minus 0.007". Most film has a base of 0.007" . When film is loaded in the film holder, the depth is 0.190". This is the measurement used by Sinar cameras. Wisner cameras use a compromise of 0.192" to allow for wear on the wood and because Tech Pan film, used by some photographers to achieve ultra-sharp images, has a base of 0.004".
The ANSI standard for 5 x 7 and 8 x 10 inch film holders are as follows (film thickness has not been deducted):
5 x 7"
0.228" + - 0.010
8 x 10"
0.260" + - 0.016
These measurements may
be checked with a Vernier caliper gauge or a micrometer (available in some
hardware stores).
Venire calipers take measurements
to 0.1 mm or less.
NOTE: I think this is for the 14X17 holder.
Height =19.563" minimum
Width =
15.938"-16.000"
Thickness =0.686" maximum
Depth to septum (T) = 0.320" -
0.016"
The far edge of the raised ledge that fits into the slot on the
camera back
is19.288" maximum from the end of the holder where one loads the
film. It
should be 0.061" +/- 0.015" high.
The bottom flap (F) is 1.043"
maximum.
