How to set any font size (e.g. 32pt) with \setbeamerfont?

Question

I want to set font size for frametitle with \setbeamerfont. How to set any font size (e.g. 32pt) with \setbeamerfont?

Answer 1

After reading the manual, I found the answer! It's simple:

\setbeamerfont{frametitle}{family=\rmfamily,series=\bfseries,size={\fontsize{32}{36}}}

where 32 is 32pt, the font size and 36 is the skip line size in pt.
