Hello - I recently discovered Context so let me first of all say a big thank you to Hans for creating such an amazing piece of software and making it available. Now, the question - this works exactly as I expect: \setupcolors[state=start] \setuppagenumbering[state=stop] \setuppapersize [XY][A4] \setuppaper[nx=3,ny=10,dx=0mm,dy=0mm,topspace=5mm,backspace=5mm] \setuplayout [location=middle] \setuparranging [XY] \showframe \starttext \dorecurse{15}{test \recurselevel \page} \stoptext However, when I change A4 to letter the output seems to introduce some "dy". I experimented with some other paper sizes including defining my own and see inconsistent results. Can anyone point out what I'm doing incorrectly? Thank you very much for any assistance, Matt \setupcolors[state=start] \setuppagenumbering[state=stop] \setuppapersize [XY][letter] \setuppaper[nx=3,ny=10,dx=0mm,dy=0mm,topspace=5mm,backspace=5mm] \setuplayout [location=middle] \setuparranging [XY] \showframe \starttext \dorecurse{15}{test \recurselevel \page} \stoptext CONFIDENTIAL: This e-mail, including its contents and attachments, if any, are confidential.
