Re: mom and custom page sizes

[Oliver Corff]

Hi Marcus,

without having tried your example, it comes to my mind that the text if
formatted the way you want it to have, but the media box of the pdf is
set to A4 or letter (depending on the default configuration of your system).

After that thought, I gave it a try, et voilà, this is the media box of
the pdf file:

/MediaBox [0 0 612 792 ]

No wonder you look at an A4 or letter sheet of paper.

The answer to your problem is on page 5, bottom, of
/usr/share/doc/groff/pdf/mom-pdf.pdf, "Producing PDFs with groff and mom".

Best regards,

Oliver.
