Severe Covid-19 restrictions locally have left me out on a limb unable to be side-byside with people who can set me on track for a few things! Hence the bombardment of questions, for which I apologise. But almost there! The InDesign QC individual (who accepts my ConTeXt-produced pdfs) wants some tweaking to my layout, saying, in simple terms:/Odd/right pgs left margin should be 20mm and right margin 15mm; even/left pgs right margin 20mm and left margin 15mm/. I think the difficulty is that what InDesign calls margins might be termed a little differently in ConTeXt and I have no experience with InDesign. My initial setup was as follows for a paper size defined as [width=140mm,height=216mm] double-sided setup (in other words a standard 8.5"x5.5" book): \setuplayout [backspace=16mm, topspace=12mm, header=6mm, headerdistance=10mm, footerdistance=9mm, footer=8mm, width=fit, horoffset=12.7mm, location=middle, height=198mm, marking=on] There was no mention of 'margins' as such in that layout, and the result is close to what is wanted but not quite. Do I solve the problem by adding in: leftmargin=20mm, rightmargin=15mm, or is it some other item I need to adjust to ensure the 20mm/15mm dimensions requested? Julian
