    Take a look at the answer to: http://tex.stackexchange.com/questions/2414/how-can-i-have-a-bigger-integral-int-delimiter as I suspect that that might solve your problem. If it doesn't, please edit your question to explain why that doesn't work so answerers can better help you. If it does, this question will be closed as a duplicate of that one to help others find the answer quickly. – Andrew Stacey Mar 03 '11 at 09:03

You can do that with the package bigints

For example,

\documentclass{book}
\usepackage{bigints}
\begin{document}

    \begin{align}
    \bigints_{-Y}^{Y}\left(\frac{X}{\frac{X}{\frac{X}{X}}}\right)\mathrm{d}X
    \end{align}

\end{document}
