Hi @Jonathan Ratchford,
Margins are drawn from the edge of the physical page dimensions inward to the specified margin setting. If a report item extends into the margin area, it is clipped so that the overlapping area is not rendered. If you specify margin sizes that cause the horizontal or vertical width of the page to equal zero, the margin settings default to zero. Margins are specified using the Report Properties pane, Page Setup dialog box or by changing the TopMargin, BottomMargin, LeftMargin and RightMargin properties in the Properties pane. If you want to override the margin size that is defined in the report, you can specify the margin size using the Device Information settings for the specific renderer that you are using to export the report.
The area of the physical page that remains after space is allocated for margins, column spacing, and the page header and footer, is called the usable page area. Margins are only applied when you render and print reports in hard page break renderer formats. The following image indicates the margin and usable page area of a physical page.
See Pagination in paginated reports (Microsoft Report Builder)
