Hi, Using the 'backspace' key worked for setting up equal margins for my downloadable version. I created a mode for printing where I used the following values: \setuplayout[ rightmargin=52pt, leftmargin=52pt, backspace=16pt, ...] Unfortunately the text width is not equal to 312pt as in hte downloadable version. I used these values since I infered that we have: ** left and righ margins on the sides of text, ** backspace which is an additional space in the gutter. Following the setup I described in the printable version I would get or I at least wanted: 52pt outer margins and 68pt inner margins. Is my reasoning correct or I am missing something? Thank you for explanation. I keep asking for I want to fix my layout and there may be others who may find it useful in the future.
