You can get the bounding box but not the "ink box". In LaTeX terms,  
it's something like:

\newlength\lengtha
\newlength\lengthb
\newlength\lengthc
\settowidth\lengtha{a}
\settoheight\lengthb{a}
\settodepth\lengthc{a}

The calc package also provides the \lengthof{} (etc.) macros when  
calculating lengths.

Hope this helps,
Will
