# Linebreaks in title cause wrong line spacing

On the title page of my thesis, I have a rather long title (on three lines), but I would like to specify which words fall on which line, because the default doesn't look good. Say I just use \textbf{\LARGE{I have this really long title And I want to break it At specific locations}} produces a page like this: I highlighted the places where I want to break the line with capital letters.

But if I do this: \textbf{\LARGE{I have this really long title\\ And I want to break it\\ At specific locations}}, the lines break correctly, but there is this gap produced, which I don't understand and definitely don't want.

It must be something to do with some of my settings or loaded packages? This is the preamble and settings of the document:

So how can I get my linebreaks AND line spacing correctly?

• I don't know what half of your packages do, and I doubt you do either. I would suggest you throw out everything and add packages when and if you need them. First, double spacing is for typewriters, not typesetters. Don't use it. Second, the starred version of \vspace is only useful a the top or bottom of a page. Also, if \vspace is entered in the middle of a line, it will not be implemented until the end of the line. – John Kormylo Dec 12 '17 at 4:24
• Well, I am using a template handed down from one generation of students to another. You are right, I don't know what latexsym, syntonly, textcomp packages do - they were already a part of this template. But too many things went wrong when I tried to remove the packages or formatting commands that I didn't know. And for a two-line title, this works fine. – durbachit Dec 12 '17 at 5:11
• But I see what you mean that \vspace only works at the end of the line! – durbachit Dec 12 '17 at 5:32

Note that \baselineskip is a function of the font size.

\begin{titlepage}
\begin{center}{\LARGE\baselineskip=2\baselineskip% if you really need double spacing
\vspace*{\baselineskip}
\textbf{I have this really long title\\ And I want to break it\\ At specific locations}

By \vspace{\baselineskip}\\
