This seems like an easy question, but I haven't found any hints on this, so: How do I resize the output of FeynMF
and the labels within it?
I use it like this:
\begin{enumerate}
\item Feynman diagram:\\
\begin{fmffile}{fgraph_tau}
\begin{fmfgraph*}(8,5)
\fmfleft{i1,i0}
\fmfright{o1,o0}
\fmf{fermion,label=$e^+$}{i1,w1}
\fmf{fermion,label=$\overline\nu_e$}{w1,o1}
\fmf{boson,label=$W$}{w0,w1}
\fmf{fermion,label=$\overline\nu_\mu$}{i0,w0}
\fmf{fermion,label=$\mu^+$}{w0,o0}
\end{fmfgraph*}
\end{fmffile}
...
\end{enumerate}
and compile using this SE answer, which gives a nice Feynman diagram in the output pdf in the place I'd like it to be.
Now I would like to have a) the labels a bit larger and b) the overall graph itself a bit smaller. How can I achieve this?

The size of the diagram is controlled by
\unitlength
; you can also issue a font size changing command for increasing the size of the letters.
