[Tex/LaTex] titlepage is not vertically centered

titlesvertical alignment

I noticed that my titlepage is not vertically centered. I tried \vfill, \vspace{\fill}, \vspace*, and \usepackage{titling}.

\documentclass[12pt, oneside]{article}

         \usepackage{graphicx}

\usepackage{geometry}
\geometry{a4paper}
\usepackage{float}
\usepackage[american]{babel}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage[onehalfspacing]{setspace}

\begin{document}

\begin{titlepage}
\begin{center}

\begin{huge}
name of university \\
\end{huge}

\begin{figure}[H]
\centering
\includegraphics[width=0.5\textwidth]{Unilogo}
\end{figure}

\vspace{1cm}
{\Large name of institute} \\
\vspace{5mm}
Research focus \textit{research name} \\
Project \textit{project name} \\
\vspace{2cm}
\begin{large}
\textbf{title of thesis} \\
\end{large}
\vspace{5mm}
Master thesis in Biomedical Sciences \\
Submitted on Date \\
\vspace{1cm}
name \\
Matriculation number: \\
\vspace{2.5cm}
\begin{tabular}{rl}
{\bfseries Supervisors} & name and name\\
{\bfseries Examiners} & name and name \\
\end{tabular}

\end{center}
\end{titlepage}

\end{document}

Best Answer

When you have markup such as

Submitted on Date \\
\vspace{1cm}
name 

the vertical space is added after the line that contains name which is, I would guess, not what is intended.

Avoid all use of \\ outside tables, and always put a blank line before \vspace

Submitted on Date

\vspace{1cm}
name 

produces an output with the space between the two lines of text.

If you have a size change such as \huge always leave a blank line before the end of the group, or you will get huge text set on a normal size baseline.

Don't use figure inside a titlepage, just include the graphic.

You can vertically centre with \vspace*{\fill}
