Koma Classes: Add to Header

header-footerkoma-script

The running headers for my document appear too high on the page. The manual isn't clear as to where the switch should go (after scrlayer-scrpage? or as a class option?

\documentclass[twocolumn,a4paper,9pt,BCOR=15mm,headheight=20.5pt]{scrbook}

has no effect.

\usepackage{scrlayer-scrpage}[headheight=20.5pt] 

has no effect either.

What is the proper syntax?

Manual page 45:

In some cases it is useful to be able to specify the header height not in lines but directly as a length. This is accomplished with the alternative option headheight. All lengths and sizes that LATEX understands are valid for height.

You can use the geometry package in koma-script, but you should specify the usegeometry option to make it work together nicely.

The parameters that are relevant are tmargin (or top) that specify the space between the top of the paper and the headerline, and headsep which is the space between the headerline and the text. I don't know which one you want to change, but headheight is the wrong one, as it specifies how much vertical space is reserved for the headerline.

This should give you an indication:

\documentclass[twocolumn,a4paper,9pt,BCOR=15mm,usegeometry]{scrbook}

\usepackage[headsep=1cm,tmargin=1cm,includehead]{geometry}
\usepackage{scrlayer-scrpage}
