Did you try clientWidth:
https://developer.mozilla.org/en/DOM/element.clientWidth
try:
private native static int getClientHeight(Element elem)
/*-{
return elem.clientHeight;
}-*/;
and
private native static int getClientWidth(Element elem)
/*-{
return elem.clientWidth;
}-*/;
See:

Kind Regards,
George.
