I have an issue trying to set my margins on LyX. I am using a two-sided document, the box for this option is checked. I've set the value of inner margins (4cm) and outer margins (2cm), but on my Pdf I always have my 4 cm margin on the left and the 2cm one on the right...

Any Idea?

Thank you!

Menu DocumentConfigurationDocumment classOption class ⇢ Write here the twoside option, so after fix the margins, the LaTeX source show something like this:


Then add some content and voilá.

If you want reproduce this minimal working example (MWE), it is a default document (article) with an ERT box (Ctrl+L) with \lipsum[1-50] to make the dummy text. This need the package lipsum: DocumentConfigurationLaTeX preamble ⇢ Write \usepackage{lipsum}. So this simple document:

enter image description here

will produce this LaTeX source:

%% LyX 2.1.2 created this file.  For more info, see ttp://www.lyx.org/.
%% Do not edit unless you really know what you are doing.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% LyX specific LaTeX commands.
