IMO the best way is to resize window after document in frame is loaded. Actually I don't see any other way. You need to get frame element, then attach handler to load event to resize window. You can get iframe document by calling var innerDoc = (frame.dom.contentDocument) ? frame.dom.contentDocument : frame.dom.contentWindow.document; and then access document height by innerDoc.body.scrollHeight.
