I'm out of my depth, I've looked at the s-*.tex layouts, and have read chapter 3 of the manual, but am not confident in designing a page layout. For instance, I'm not sure how I ensure that vsize comes out as a multiple of baselineskips, or how to ensure that double sided pages are printed correctly. My initial design parameters (for a double sided page) are: 1) paper size = A4 2) hsize = 2.5 times the length of the lowercase alphabet in the default font -- lucida-bright at 12pt. i.e. \setbox0={abcdefghijklmnopqrstuvwxyz} \hsize=2.5\wd0 3) vsize = golden-ratio times hsize (rounded to integer baselineskips) = 1.62\hsize 4) backspace margin = hsize divided by seven 5) topspace margin = backspace margin. How do I translate these into my \setuplayout parameters?
