Hans, I know I've asked you this before ... I just can't find the answer anymore ;o( Look at line 43: \newdimen\XVertikal \XVertikal=12pt \setupbodyfont[postscript,10pt] \setupinterlinespace[line=\XVertikal] \setuplayout [width=113mm,height=\the\dimexpr48\XVertikal-2pt\relax, backspace=20mm,topspace=15mm, header=\XVertikal,headerdistance=0.5\XVertikal, footer=3.5\XVertikal,footerdistance=0pt, location=middle,marking=on,grid=yes] \showframe \showgrid \starttext bla \stoptext ... when "height" is made 2pt smaller then it fits: \newdimen\XVertikal \XVertikal=12pt \setupbodyfont[postscript,10pt] \setupinterlinespace[line=\XVertikal] \setuplayout [width=113mm,height=\the\dimexpr48\XVertikal-2pt\relax, backspace=20mm,topspace=15mm, header=\XVertikal,headerdistance=0.5\XVertikal, footer=3.5\XVertikal,footerdistance=0pt, location=middle,marking=on,grid=yes] \showframe \showgrid \starttext bla \stoptext Does this difference has a specific purpose? Would you recommend *not* to use the second? Steffen
