I came here to understand why latex had this "odd" habit to set the outer margin wider than the inner in two sided documents.

As many have asked before me, I expected the inner margin to be wider to take into account the binding space. From the answer to those questions I discovere that the outer margin should be wider that the inner and that the inner margin does NOT takes into account the binding space (since it's not universal but depends on the binding type).


I need to give the print shop a PDF version of the thesis ready to be printed. When I went there today he told me that usually the inner margin is wider to take into account the binding and to be equal to the outer once it's bond.

I accept the "outer margin is wider" standard, but I need to add a bit of binding space to my pages. How do I do it?

It's the first time I print a two sided document. If I told something wrong feel free to teach me how to setup (maybe also outside of latex) correctly a two sided document.

Thank you very much

    Using the geometry package you can set the bindingoffset=⟨length⟩. The length depends on the page number and binding type. – DG' Jul 16 '14 at 8:51
  • You can read some explanations on page margins in section 2 of the KOMA-script documentation (texdoc scrguien). – Johannes_B Jul 16 '14 at 8:52

    latex detects what's an outer and what's an inner margin from the page number: it expects odd pages to be right-side in a double-page spread, even pages to be left-side. this is why macros like \chapter throw a blank page in two-sided mode. it's possible to get this wrong, but if you are using a class that does ‘standard’ \chapter commands (like report or book classes) it's hard to keep it broken(!). we need a minimal example of your problem... – wasteofspace Jul 16 '14 at 9:02
  • You can also see my short explanations on this site: tex.stackexchange.com/questions/183995/…. Note that the French canon des Ateliers I mention already takes into account a binding correction. since the inner margin is a little more than half the outer margin. – Bernard Jul 16 '14 at 9:02

    It is far more common in printed works for the outer margin to be wider (it is not for binding, this is the visible white space) the margin is for your thumb to hold the page and for scribbling in. – David Carlisle Jul 16 '14 at 9:31
