[Tex/LaTex] Change paper size in winedt

paper-sizewinedt

I am using sig-alternate-2013 (http://www.sheridanprinting.com/typedept/sig-alternate-2013.cls), which is supposed to print in US letter page size (8.5×11 inches), but I am now printing in A4 size (21×29.7 cm), how should I change it?

I am currently using WinEdt 8, there is some suggestions here:

but I can't get it work.

To get letter paper try this:

\paperwidth=8.5in
\paperheight=11in
\usepackage{graphicx}

which should work with most engines/drivers.
