# Wrong vertical spacing in twocolumn mode

I want a consistent spacing between the top of the page and the table-of-content-title/ chapter-titles throughout my document. However, in two-column mode, it appears that the space between the top of the page and chapter-title is a little bit smaller than the space between the top of the page and the table-of-content-title:

In one-column mode, the spacing is always the same. How can I keep the spacing equal in two-column mode?

MWE:

\documentclass[11pt, openany]{scrbook}
\usepackage{lipsum}

\begin{document}
\tableofcontents

\twocolumn % Comment this out and the spaces become right again

\chapter{Test Chapter}

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

\end{document}


There is a vertical space missing before the chapter-titles. But there is the same problem with the standard classes, see this entry in the LaTeX bugs database.

As a workaround with KOMA-Script versions 3.16 or newer (3.17a is the current version on CTAN) you could use

\makeatletter
\makeatother


Code (without the grid):

\documentclass[open=any,
twocolumn
]{scrbook}[2015/02/07]
\usepackage{showframe}
\makeatletter
\makeatother
\begin{document}
\tableofcontents
\chapter{Test Chapter}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
\KOMAScriptVersion
\end{document}


And as reference: The same code without twocolumn and without the workaround

\documentclass[open=any,
%twocolumn
]{scrbook}[2015/02/07]
\usepackage{showframe}
%\makeatletter
%\makeatother
\begin{document}
\tableofcontents
\chapter{Test Chapter}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
\KOMAScriptVersion
\end{document}


results in

Update

If you want to switch between twocolumn and onecolumn inside the document you could use something like

\documentclass[open=any,
twocolumn
]{scrbook}[2015/02/07]
\usepackage{showframe}

\makeatletter
\makeatother

\newcommand\mytwocolumn{%
\KOMAoptions{twocolumn=true}%
}
\newcommand\myonecolumn{%
\KOMAoptions{twocolumn=false}%
}

\begin{document}
\tableofcontents
\chapter{Test Chapter}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
\KOMAScriptVersion

\clearpage
\myonecolumn
\chapter{Test Chapter}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

\clearpage
\mytwocolumn
\chapter{Test Chapter}
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
\end{document}


Note, the definiton of \tcchapterheadstartvskip have to be changed if the parskip Option is used.

With parskip or parskip=full:

\newcommand*\tcchapterheadstartvskip{\vspace{\topskip}\vspace{\baselineskip}\vspace{\@tempskipa}}


And with parskip=half:

\newcommand*\tcchapterheadstartvskip{\vspace{\topskip}\vspace{.5\baselineskip}\vspace{\@tempskipa}}

• Thank you for your help. However, I have noticed that the same wrong spacing appears also for the bibliography. – klopps May 12 '15 at 23:24
• @klopps There is no bibliography in your MWE. Nevertheless maybe my updated answer will help. – esdd May 13 '15 at 13:32
