Notes:

          Flaps depending on the camera manufacture and time period the camera was made the width may be different.

          The first column listing flaps size is the standard and currently used by US camera makers

          Lock rib measurement is from the flap end to the far side of the lock rib 

          ANSI publication for smaller holder states " Dark slide handles shall have tactile identification marks on one side (usually the white side) to differentiate exposed and unexposed film.
