In the scrbook class, my running headers are too high. I've looked at page 44 of the manual ("Calculating the Page Layout with typearea") but while this addresses two line headers, it does not explain how to drop headers that are too high. This is the class option I am using:






\chapter{Chapter 1}
\section{Section 1}


\section{Section 2}


  • By "too high" I mean extending into the bleed.

  • .375mm, specifying lengths in .001 mm??? but koma has extensive built in ways to specify the layout, including paper=6in:9in,BCOR=7.5mm,headlines=2 it isn't clear that loading geometry on top will work well Jul 3, 2023 at 16:19

    your example ends with the warning LaTeX Font Warning: Size substitutions with differences (Font) up to 1.02895pt have occurred. so you are tolerating .4mm difference in font size on every line but specify margins of less than .4mm specfied to 3dp on the page. First I'd double check with the printer those margins which seem weird why have page size in inches and margins in mm? but simply commenting out %\KOMAoptions{DIV=calc} %\recalctypearea will let geometry have control and you get the specfied margin (ie no margin at all, essentially) Jul 3, 2023 at 18:21

    Do you really want the margins to be as small as technically feasible? It seems to me that your printer probably specified a minimum margin (i.e. "Here's where I can't print."). Since any reasonable text margin (like the KOMA defaults) is much larger than that, there really is no need to do anything about it, at least not for the printer's sake. What is the typesetting result you want?

    @user26732 Well, if you want to set the layout page layout manually, use the geometry package (or the TeX registers directly) and do not use KOMA Script's layout functions. Have a look at the layout package if you are unsure on the meaning of the lengths.

Inserting this code drops the running headers as required:


The key line is the \ohead command. If you omit the last line you lose page numbers.
