latex letterpaper & dvipdf

[roberto <roberto03@gmail.com>]

hello

i am struggling at writing a paper and i have to respect the options
"letterpaper"
which is default in IEEEtran.cls
but when i open the pdf by acrobat it defaults to
8.26*11.69in

instead of:
8.50*11in

my header contains:

\documentclass[letterpaper]{IEEEtran}

so i do not know if it may be a problem in dvipdf conversion after
that i generate the pdf from the dvi.
do you know how to set the option "letter" in dvipdf?
man page seems to be rather short...

thank you!
