[Tex/LaTex] Beamer/Beamerposter Line spacing in title doesn’t seem to work

beamerbeamerposter

I'm trying to increase the linespacing in the title section, and I feel like I've tried a lot of things, but none of them seem to work. Whenever I use \fontsize{32}{36}, the second parameter doesn't seem to do anything (yet the first one, does indeed change the size).

Also, as more of an aside, if anyone also knows how to make the section not be in the centre of the poster, but rather, directly underneath the university, that'd be great.

This is the .tex:

Best Answer

Try to put the title inside a minipage

\setbeamerfont{title}{series=\bfseries,size=\fontsize{100}{50}}

\begin{minipage}[b][0mm][t]{.45\paperwidth}%
    \usebeamercolor[fg]{title in headline}{%        
        \usebeamerfont{title}{%
            \normalbaselines%
            \inserttitle\par%               
        }%
    }%
\end{minipage}%
