# Change title page margins and BCOR

I have the following main document, which is normally a lot longer. In general, I have the title page in a separate document and include this via \include{titlepage}. How can I change the margins and BCOR for the title page only, so that the title sits in the centre of the page? I tried titlepage=firstiscover,titlepage=true, and \begin{fullsizetitle} as recommended here which all did not work. I also tried to compile the title page separately and include the pdf, but this produces a clash with pgfplots.

\documentclass[a4paper,
twoside,
openright,
DIV=10,
BCOR=10mm,
{scrreprt}
\begin{document}
\begin{titlepage}
\begin{center}
\vspace*{\fill}
\Huge
{\textbf{Title}}\\

\vspace{1cm}
\Large
{Subtitle}\\

\vspace{3cm}
\normalsize
{University of ...\\}
\end{center}
\vspace*{\fill}
\vspace{3cm}
\end{titlepage}
\end{document}

• Please note that the center environment might add unwanted space. If you're in an environment already, it is advised to use \centering instead. Jan 30 '20 at 12:13

The titlepage=firstiscover option does only work on \maketitle not on the titlepage environment. The following copies some of the code used in \maketitle if the option titlepage=firstiscover was used and inserts it into your titlepage. I've added a \rule just so one sees that the margins are indeed correct. I've also added some dummy content so that you can see that the margins are restored after the titlepage environment.
