Remarks

SetPageSize sets the width and height of the Map in inches.
In the ArcMap application, the Map width and height are set to 0 inches by 0 inches in data view; in layout view, the Map's size is by default set to fit within the page size (IPage::QuerySize).
Developers creating their own application may use SetPageSize to set the size of the Map in their own page space.
