Axel,
Many thanks for your reply.
After reading your comments I experimented with my file and discovered
that the delimiter size discrepancy occurs when I use the command
\usepackage{exscale,relsize}. The delimiter size discrepancy does not
occur when I comment out this command.
Since I need to use these packages, I will follow your advice and set
the delimiter size myself.
I welcome your comments.
Regards,
Raul Martinez
Here's the test file
--------------------
\documentclass[12pt]{article}
%-------Packages----------------------------------------
\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{amsmath,amssymb,bm}
\usepackage{exscale,relsize}
\begin{document}
\begin{equation}
\begin{split}
K_z &= \frac{1}{\left( \sigma_{x}^{2} + \sigma_{y}^{2}\right)^{2}}
\: \left(\mathcal{E} \left\{\left( X- \eta_x \right)^4 \right\} +
\mathcal{E} \left\{\left( Y- \eta_y \right)^4 \right\} \right. \\
& \quad \quad +\left. 2\,\mathcal{E} \left\{\left( X- \eta_x
\right)^2 \left( Y- \eta_y \right)^2 \right\} \right)
\end{split}
\end{equation}
\end{document}
