Hans, after enabling image scaling in \insertpages (https://mailman.ntg.nl/pipermail/ntg-context/2016/086114.html), I’m afraid that the default value and compatibility in imposition is broken. The minimal sample is the following: \setuppapersize [A5][A4,landscape] \setuparranging [2UP] \setuplayout [backspace=0pt, topspace=0pt, width=middle, height=middle, location=middle, header=0pt, footer=0pt] \setupinteraction[state=start] \setupinteractionscreen[option={landscape, paper}] \starttext \insertpages[whichever-document.pdf][width=0pt] \stoptext Would it be possible to restore the width value to its previous default? Many thanks for your help, Pablo -- http://www.ousia.tk
