The pdf from the tex below looks wrong to me, screenshot attached. It’s always like this when the page number in the second \definelayout is 1 more than the page number in the first. For other pairs of numbers, it behaves like I expect: the short layout is only on those 2 pages. I’m using the LMTX I updated a few days ago. ConTeXt online’s pdf is the same. %====================================================== \showframe \setuppapersize[A4][A3,landscape] \setuparranging[2SIDE] \setuplayout[backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=200mm, margindistance=10mm, leftmargin=40mm] \definelayout[short][backspace=80mm, width=100mm, topspace=50mm, header=0mm, footer=0mm, height=80mm, margindistance=10mm, leftmargin=40mm] \starttext \definelayout[2][short] \definelayout[3][short] \dorecurse{10}{\input{knuth} } \stoptext %====================================================== Also, https://wiki.contextgarden.net/Command/definelayout says: % different layout for first two pages \definelayout[1][wide] \definelayout[3][reset] This does not work for me.
