This image illustrates the concepts of physical and logical pages. One logical page is made up of six physical pages. The logical page is three physical pages wide and two physical pages high. Consequently, Horizontal Panels per Page size is 3 and Vertical Panels per Page size is 2. If you wanted the logical page to be two physical pages wide and three physical pages high, you would specify a Horizontal Panels per Page size of 2 and a Vertical Panels per Page size of 3.
