I'm trying to create a booklet A4 which is folded "the long way", in other words such that the resulting page size is not an A5 page but rather two A6 "on top" of each other.
I changed the paper size successfully by loading the
article class with the
a4paper option and putting in my preamble
However, this of course didn't change any of the lengths controlling text width, margins etc. So I assume there must be another, better way.
