How to increase the font size and make a boldface of the whole symbol given above in mathmode in Latex ?

Best Answer

Using \bm command from bm package and \scalebox from graphicx package.

enter image description here

Code:

\documentclass{article}
\usepackage{bm,graphicx}

\begin{document}
\centering

Normal
\[\sigma_{E_{1}}^{(l)}\]

\bigskip

Bold
\[\bm{\sigma_{E_{1}}^{(l)}}\]

\bigskip

Bold and bigger
\[\scalebox{2}{\ensuremath{\bm{\sigma_{E_{1}}^{(l)}}}}\]

\end{document}

The latter can be used outside math mode, as well. Adjust the factor 2 to meet your needs.
