Question : HTML site appearing full width in IE, not in other browsers, how to reduce size - center

I have a site

www.simonramsey.com/Clients/Bilal

the page looks like it has zoomed larger in IE, the whole width of the browser, not so in other browsers. I want to reduce the size of the
page so that it appears in the center of the browser, with a gap on each side of the main div.

How do i do this?

thanks in advance for any help!
