The master page determines the dimensions and style of the pages on which report data appears. For example, you can specify that the page size is 7" x 9", the printable area is 6" x 8", the company logo always appears in the top right corner, and the page number appears in the bottom right corner.

The page size and margin settings apply primarily to reports in PDF, DOC, and PPT formats, where size dimensions matter, because these document types are page-oriented. For HTML reports that use the default fixed layout setting, the output appears the same as the PDF report. For HTML reports that use the auto layout setting, the layout of data adjusts to the size of the viewer or browser window.
