Unlike previous versions of QuarkXPress, to change the page dimensions of a document (Layout) in QuarkXPress 6 and above requires a trip to the Layout menu (Layout> Layout Properties> Layout Setup).
A shortcut is to Control-click (or right-click) the Layout tab. In QuarkXPress 6 and 7, the Layout tab is at the bottom of the document window; in QuarkXPress 8, the Layout tab is at the top of the document window. When you Control/Right click, you’ll see a contextual menu containing a Layout Properties option.
