I use the following document class
\documentclass[11pt,a4paper,twoside]{scrbook}
with default header and footer (chapter/section in header and the page number in the footer)
My problem is, that the ratio between the margin of the header and the footer is not 1:2 when considering the header but not considering the footer. It is always 1:2 considering header and footer. I already tested the commands headinclude and footexclude, but it did not solve the problem.
Does somebody have an idea how to solve this issue?
