# improving different textwidths of facing sides with reledpar

Using reledpar to print a modern translation with its facing Latin original results in huge white spaces between the chunks because of Latin's famous compactness and the very long paragraphs of this particular text.

A possible solution to make the result more pleasing and easier to consult would be to make the left pages' textblock narrower. This can be done by setting \Lcolwidth which works fine.

I am looking for a way to also adjust the headsepline (which I need to keep in this specific case) on the left pages and/or a way to center the contents of the left sides on the page to achieve a visually more pleasing result.

(I'd prefer to keep the scrbook-class but this is not strictly necessary.)

• I don't see any easy way, no, to do that. Maybe I could add an hook to be executed at each pages change. But maybe your problem could be solve using reledpar synchronization setting, for example shiftedpstart – Maïeul Sep 13 '18 at 21:22
• Thank you @Maïeul ! So I know I have to look for another solution. Perhaps I could leave the line to begin with and superimpose it later… Moving the texblock to the center will probably be more difficult. I will look more closely at shiftedpstart or other solutions. – Florian Sep 14 '18 at 10:23
• Ok, centering as such is easy as \leftskip/\rightskip can be set within the Leftside environment (duh!). We cannot move the linenumbers easily, can we? – Florian Sep 14 '18 at 10:40
• what do you mean by move the line number? the distance between line number and is determined by linenumsep, which value is the same for both side. – Maïeul Sep 14 '18 at 17:23
• yes, I would have liked to change the linenumsep individually for the left side. But it just occurs to me that it is possible to hack this by setting \linenumsep to fit for the narrow left side and putting hspace into \setRlineflag. Ugly, but seems to work. – Florian Sep 14 '18 at 18:15
