I may be wrong, but I believe it has nothing to do with photographic
printing. The size is based in offset printing. It fits an 11 x 17 spread
with room for bleeds and all printer's/registration marks. I think it has a
European basis, but that's just because it's referred to as "Super B" or
"Super A4," and Europeans name all their sheet sizes with letters, rather
than with inch dimensions like we do in the US. Their standard page sizes
are different than those we use in the US.
