I'm only talking about horizontal extents of the generated pdfs. The bar
numbers on the left are no problem, because we use
"-deps-box-padding=3\\mm" to add an additional 3 mm on the left for the
bar number (and reduce the line-width by the same amount).
What I'm observing is that the pdf is always a bit larger (more than
0.5mm, but usually less than 1mm) than the line-width plus the 3mm left
padding. I have not yet investigated in how far bar lines on the right
end increase it. I suspect that it has an influence.

It should work independent of the paper size, since we only extract the
line-width from texinfo or latex and then simply handle that to lilypond
as a numeric value. LilyPond simply creates a score with this line-width
and then crops the image, leaving a small amount of extra space on the
right, which I think is the cause of this problem.
