[Tex/LaTex] Why is a blank page inserted

blank-pagekoma-script

The following produces a blank page – page 2.

\documentclass[a4paper]{scrreprt}
\author{}
\date{}
\def\myversion{1.0 }
\title{
\flushright
    \rule{14.5cm}{5pt}\vskip1cm
    \Huge{SOME TEXT IS\\ WRITTEN HERE}\\
    \vspace{2cm}
    text\\
    \vspace{2cm}
    some text here\\
    \vspace{2cm}
    \LARGE{Version \myversion \\}
    \vspace{2cm}
    A line of text
    \vspace{1cm}
    \rule{14.5cm}{5pt}
}
\begin{document}
\maketitle
\tableofcontents
\chapter{Here's a heading}
\end{document}

I've noticed that if I remove the last two lines of the \title that the blank page disappears. This leads me to believe there's some magic number that defines how much content can fit on the first page before it will end up causing a successive blank page to be inserted.

How can I determine what this magic number is, and can I change it?
If I'm wrong, how else can I have the full content of \title displayed on the first page and not have a blank page inserted on compile?

You have to have some trial and error to find out how much more space is needed so as to keep things intact. For example, here \vspace*{-\baselineskip} will do the job.

\documentclass[a4paper]{scrreprt}
\author{}
\date{}
\def\myversion{1.0 }
\title{%
\vspace*{-\baselineskip}
\flushright
    \rule{\linewidth}{5pt}\vskip1cm
    {\Huge SOME TEXT IS\\ WRITTEN HERE}\\
    \vspace{2cm}
    text\\
    \vspace{2cm}
    some text here\\
    \vspace{2cm}
    {\LARGE Version \myversion \\}
    \vspace{2cm}
    A line of text
    \vspace{1cm}
    \rule{\linewidth}{5pt}
}
\begin{document}
\maketitle
\tableofcontents
\chapter{Here's a heading}
\end{document}

However, when you tweak the title so much, it is advisable not to abuse \title command. Use titlepage instead.

\documentclass[a4paper]{scrreprt}
\def\myversion{1.0}
\begin{document}
\begin{titlepage}
  \flushright\bfseries\huge
  \vspace*{\stretch{0.4}}
    \rule{\linewidth}{5pt}
    \par
    \vspace{1cm}
    {\Huge SOME TEXT IS \par WRITTEN HERE \par}
    \vspace{2cm}
    text\par
    \vspace{2cm}
    some text here\par
    \vspace{2cm}
     Version \myversion \par
    \vspace{2cm}
    A line of text
    \vspace{2cm}
    \rule{\linewidth}{5pt}
    \vspace{\stretch{1}}
\end{titlepage}
\tableofcontents
\chapter{Here's a heading}
\end{document}

Here you have to adjust every thing by yourself.

[Tex/LaTex] unwanted blank page inserted before tabular

As Martin points out, this is related to the booktabs rules. There really shouldn't be a \midrule between every line, but if you want to do it anyway, here's one way to fix the problem.

\documentclass[a4paper,11pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{supertabular}
\usepackage{array}
\usepackage{booktabs}
\usepackage{geometry}
\usepackage{etoolbox}

\tabletail{\bottomrule}
\tablelasttail{\bottomrule}
\tablehead{%
        \toprule
        \multicolumn{2}{c}{\textbf{\huge ``Head row''}}%
        \\ \midrule
}

\pagestyle{empty}%

\appto\estimate@lineht{%
        \global\advance\ST@lineht by\aboverulesep

The geometry package is just because your table was too wide and it was giving overfull rules. Changing the margins fixes that. The real fix here has to do with how supertabular estimates the height of each line. It uses \estimate@lineht to compute the height of a stretched line. Since you are using \midrule between every line, we can simply increase the estimate of the line height by incrementing \ST@lineht by \aboverulesep + \belowrulesep.

The real fix is to omit the \midrules. It makes the table look much better.

[Tex/LaTex] Extra blank pages inserted when using \cleardoublepage and \newgeometry

Explicitly compensating the \topskip, instead of setting it to 0pt, solved the problem and no extra space is put at the top.

\newcommand\th@centered[1]{\hbox{}\vspace*{-\topskip}\vspace*{\fill}{\centering#1\par}\vspace{\fill}}
