Your expectation is indeed resonable. As an aside, mandoc(1) syntax was designed to satisfy exactly that expectation, see the mandoc -O width= argument here: https://man.openbsd.org/mandoc.1#ASCII_Output The reason i took the liberty to use the mandoc-specific -O option for this purpose is that i failed to find a command line option in groff doing what a reasoable user would expect and might indeed need. > It doesn't seem like a man(7)-specific thing (it may be implemented for > -man only, but that seems non-obvious to me).

The generic feature to control the line length is the roff(7) .ll request. $ cat tmp.roff some words on a single input line $ (echo .ll 12; cat tmp.roff) | groff -T ascii | head -n 3 some words on a single input line $ echo .ll 12 | groff -T ascii - tmp.roff | head -n 3 some words on a single input line I'm not aware of a groff option to merge parts of the command line into the groff input stream - well, -r is a bit like that, but only for registers, not for requests.
