First I built a letter-on-tabloid booklet like this: \definepapersize[tabloid][width=11in,height=17in] \setuppapersize[letter][tabloid] \setuparranging[2UP,rotated,doublesided] \setuplayout[width=7in,location=doublesided,backspace=0.73in, topspace=.0in,height=10.3in] This worked pretty well. For the next iteration I wanted to reduce the size by one half, in other words a half letter sheet on a letter sheet. I came up with this: \definepapersize[halff][width 5.5in,height=8.5in] \definepapersize[ful][width 8.5in,height=11in] \setuppapersize[halff][ful] \setuparranging[2UP,rotated,doublesided] Now no amount of fiddling with \setuplayout parameters seems to place the logical pages correctly on the paper. If I use no such parameters whatever the entire physical page image seem to slide toward the bottom of the piece of paper. As a result the bottom logical page slides halfway off the page. Can anyone spot an obvious goof?
