Desired outcome: a multipage booklet on letter size paper with margins lined up when duplex printed and folded.

Using imposition with [letter][letter,landscape] did not work, so to start I used:

\definepapersize[booklet][width=140mm,height=216mm] \setuppapersize[booklet][letter,landscape] \setuparranging[2UP,doublesided] \setuplayout[width=115mm, leftedge=0mm, leftmargin=0mm, backspace=15mm, rightmargin=0mm, rigthedge=0mm] \showframe \starttext \dorecurse{8}{\input Ward \page} \stoptext

but the inside and outside margins do not line up. Where is the elegant path?

1. Set your document doublesided with

\setuppagenumbering[alternative=doublesided]

2. Reduce the width of the backspace

\setuplayout[backspace=10mm]

Thank you Wolfgang. Follow-up question: how to have a right margin appear on the right side of every booklet page? The layouts I have tried with the following mwe put the right margin on the cut side of the paper, but that “reverses” the margin side from the reader’s view when printed and folded. \definepapersize[booklet][width=140mm,height=216mm] \setuppapersize[booklet][letter,landscape] \setuppagenumbering[alternative=doublesided] \setuparranging[2UP,doublesided] \setuplayout[ width=90mm, leftedge=0mm, leftmargin=0mm, backspace=15mm, rightmargindistaince=3mm, rightmargin=25mm, ] \showframe \starttext \dorecurse{4}{\input ward \page} \stoptext
