The closest thing to a "standard" whole-plate film holder was the Kodak/Rochester, at least in the United States. There may well have been a different English/French standard. When you get into bookform holders for glass plates, the standards concept goes completely out the window. DDS-style glass plate holders might also conform to the same Rochester/Kodak standard in the US, and the UK/Fr standard elsewhere. There's probably also a yet again different standard in Germany.
My Rittreck FP holders were probably some of the last made. They measure about 7-3/4" wide or just over 195mm width. They are 10-11/16" long or about 271mm not including the dark slides. I wouldn't take these as perfect measurements but should be pretty close.
The Rittreck WP holders are considerably different from the Eastman holders. In particular, the distance to the rib lock makes the Rittreck holders too long to fit in Eastman backs, or at least the Eastman backs that I have on hand.
Rob, why do you ask? The best answer for your purposes may vary depending on what you're trying to fit to what.

Rob what are the specs on the new Ebony full plate cameras?
Ebony built its camera back to accept my Lotus holders, which were based on Lotus' 8x10 holder design. That means their T-dimension is 0.260 inch, which a number of vintage 6.5x8.5 holders also used.
Outside width of the Lotus holder is 198.0mm. Distance from taped end to start of the lock rib is 233.4mm. Thickness is 14.3mm.
Fotoman Camera is making its holders very slightly smaller in width and distance to lock rib and also using 0.260 inch for the T-dimension. That way they will be compatible with the Ebony as well as a number of vintage cameras.
