Hi there, compiling this document: \setuppapersize[A4] \setuppagenumbering[alternative=singlesided,location=middle] \starttext \showsetups \dorecurse{4}{\input dawkins \par \input knuth \par} \stoptext I should get the exact same length for left and right margin (defining margin as the total distance from the page edge to the text body edge [sorry, it isn't as accurate as it should, but I would like to avoid misunderstandings]). Setups show also that margin width and distance are equal for both sides. What I see on my laptop (and what I have seen on the printed version) is that the right margin is wider than the left one. Is there something wrong or which is the measure I'm missing? Thanks for your help, Pablo -- http://www.ousia.tk
