I am trying to customize the headers of my thesis with classic thesis and I do not know how to obtain the following result :

• left page : on the left, the number of the page, on the center, the title of the current section;
• right page : on the right, the number of the page, on the center, the title of the current chapter.

This is my preamble :

This is a view of what I am looking for :

May you help me to do that ?

• The headers in classicthesis are done with package scrpage2 of the KOMA-bundle. Have a look at the documentation. I would give you a complete solution, but i don't have all the information i need. Please add a minimal working example (MWE). – Johannes_B Sep 11 '14 at 20:49
• \ohead{\pagemark}, \cehead{\rightmark}, \cohead{\leftmark} Please note that left and right are switched as the standard is the other way around. – Johannes_B Sep 11 '14 at 20:53
• @dormi Could you bring us a full MWE? – Aradnix Sep 11 '14 at 21:02
• @Johannes_B : I tried to to what you suggest, but I changed it in this way and it does not work : \pagestyle{scrheadings} \ihead{\pagemark} \chead{\rightmark} \cohead{\leftmark} – domi Sep 11 '14 at 21:45
• Left pages are even, right pages are odd. Take a few papers in your hand, hold them with your left hand and turn the pages with your right hand. Where would you want to place page numbers? – Johannes_B Sep 11 '14 at 22:10

In French the \leftmark seems to be on the right page and the \rightmark on the left.
We should keep in mind, that classicthesis still uses the now obsolete package scrpage2. With its successor scrlayer-scrpage, the commands below stay the same.
\ohead{\pagemark}%page on the outside

• Perhaps ... Apparently in French language the \leftmark is... sounds a little bit more ... polite ;-) – user31729 Feb 18 '15 at 1:39
