Hi, please have a look at this really minimal example: \newdimen\XVertikal \XVertikal=12pt \setupbodyfont[postscript,10pt] \setupinterlinespace[line=\XVertikal] \setuplayout [width=113mm,height=48\XVertikal, 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 Why is line 43 not exactly at the bottom-line of the frame? Where does this little gap come from? This little cap is really killing when fine-tuning the page breaks: where footnotes end -> they sit on line 43, where they have to break across pages -> they sit on the frame … Jumping up and down, all through the book! Isn't my setuplayout clear enough to avoid this? Steffen
