The paper size is the physical page size. The report's rendering is determined by the paper size that you pick. REPORTS that are formatted with a hard page break When printing or viewing a hard page break file format, insert page breaks horizontally and vertically based on the physical page size to provide an ideal reading experience. Soft page break formats are used in reports. Insert horizontal page breaks based on the physical size to provide a better reading experience in a Web browser.

The page size is SET to 8.5 x 11 inches by default, but you can modify it in the Report Parameters window, Page Setup dialogue box, or the Properties pane by setting the PageHeight and PageWidth properties. The report body's contents do not CAUSE the page size to increase or decrease. If you want the report to be printed on one page, all of the text in the report body must fit on that page. If it doesn't fit and you choose the hard page break format, you'll need to add more pages to the report. A page break is inserted horizontally if the report body extends beyond the right margin of the physical page. If the report body extends beyond the physical page's BOTTOM edge, a vertical page break is inserted.
