I know that by \renewcommand{\baselinestretch}{number} it is possible to change the line distances, but it would also change the footnote distances.
How can I only change the line distances in the main text? I think there should be some changes in macros of \@footnote or some thing like this. Any idea?
memoirclass has a different command for setting the baseline stretch; for instance, 1.25 exactly corresponds to\OnehalfSpacing– egreg Dec 17 '14 at 13:23
