Hello For some reason I'm having a lot of trouble getting the page to include precisely 40 lines of text (10.5 Baskerville with an interline depth of 12 points). On an experimental file with 6 full-depth pages and no footnotes, I find that the first three have 39 lines and the second three have the desired 40 lines. You will see from the code below that I have been tinkering a lot, but it ought to be a simple matter! Can someone let me know what I should be doing? Here's the code (and I have to desert my desk now till this afternoon so am not in a hurry for an answer!): \definepapersize[OUPoctavo][width=136mm, height=214mm]%should be 216! \setuppapersize[OUPoctavo][A4] % paper size, printed on A4 \definelayout[GHIL] [edge=48pt, edgedistance=6pt, margin=72pt, margindistance=6pt, topspace=48pt, header=12pt, headerdistance=3pt, textheight=480pt,%should be 480pt, height=522.6275pt, width=24pc, footerdistance=6pt, footer=12pt, % lines=40%this messes up position on the A4 page location=middle, marking=on, horoffset=0pt, veroffset=0pt, paper=OUPoctavo] \setuplayout[GHIL] Best wishes John *🇪🇺 * Слава Україні! * 🇺🇦* http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail Virus-free.www.avg.com http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>
