It works if you apply the BCOR
option after \areaset
.
\documentclass[10pt,twoside]{scrreprt}
\areaset{12cm}{16cm}
\KOMAoptions{BCOR=5cm,paper=18cm:19cm,pagesize}
\usepackage{lipsum}
\recalctypearea
\begin{document}
\lipsum[1-10]
\end{document}
Your problem can be solved with “widetext.sty”. This package mimicing the mechanism with the same name from RevTeX4 was written by Anjishnu Sarkar. Alas, the original home went away. Luckily, we can get a copy from a svn site of Einstein Toolkit, because they have used it for a document (direct link): https://svn.einsteintoolkit.org/documents/Paper_EinsteinToolkit_2010/widetext.sty
Save this package file and put it into your folder for your actual document or, in my eyes better: put into a local TEXMF directory. Since you mentioned MiKTeX in a comment, see Create a local texmf tree in MiKTeX. But if your later want to give away the sources, do not forget to add “widetext.sty”, then.
Here’s an MWE, some explication follows below:
\documentclass[twocolumn]{scrbook}
\usepackage[nohints]{minitoc}
\usepackage{amsmath, amsthm, amssymb, amsfonts, amsbsy}
\usepackage{bigints}
\usepackage{mathtools}
\usepackage{lipsum,kantlipsum}
\usepackage{widetext}% needs packages "flushend" & "cuted" of "sttools"
% bundle, which perhaps must separately be installed
\newcommand{\dd}[1]{\hspace{2pt}d#1}
\begin{document}
\chapter{One}
\lipsum[1]
\begin{widetext}
\begin{equation}\label{fyz:fey_eq_elstat18}
E_x(x_1, y_1, z_1) =
\int\limits_{\substack{\text{all}\\\text{area}}}\varrho(x_2, y_2, z_2)
\frac{x_1-x_2}{[(x_1-x_2)^2+(y_1-y_2)^2+(z_1-z_2)^2]^{\frac{3}{2}}}\dd{x_2}\dd{y_2}\dd{z_2}
\end{equation}
\end{widetext}
\kant[1]
\end{document}
I intentionally added kantlipsum
, another dummy text package, which produces English text. So you can see, how the columns get broken.
There still seem to exist some issues, though, especially with footnotes and floats, coming from the underlying package cuted
. Its documentation says, for footnotes you should use \footnotemark
plus \footnotetext
, but in tests I was not successfull – the notes were printed much to low inside or on top of the right column below the equation depending on the actual text length, cf. code below (I added only modified parts). With \leavevmode\begin{widetext}
the output is not perfect, but much better.
Also see on TeX.SE Problems using widetext.sty (do not overlook comments to answers).

All KOMA-Script classes use
DIV=default
by default. The symbolic valuedefault
means: Calculate type area using the standard value for the current page format and current font size. If no standard value exists,calc
is used.The standard
DIV
values can be find in a table in the documentation:paper=a4
andfontsize=10pt
-> standardDIV
value: 8paper=a4
andfontsize=11pt
-> standardDIV
value: 10paper=a4
andfontsize=12pt
-> standardDIV
value: 12In your example there is
paper=a4
,fontsize=11pt
(default), soDIV=default
results inDIV=10
.The standard values does not take the used font into account. But you will get a warning by package
typearea
if there are clearly too many or too few characters in a normal text line.With
DIV=calc
takes the chosen font and its characteristics (width of the characters etc.) into account.Update
There was a bug in
typearea
: until (including) version 3.24 the standardDIV
values for fontsizes10pt
(DIV=8
),11pt
(DIV=10
) and12pt
(DIV=12
) were used even if the paper format was notA4
. This bug will be fixed in version 3.25. So if you use a version before 3.25 and not the defaultpaper=a4
Option then an explicitDIV=calc
is recommended.
