Screen shot of ReportBuilder 2012 application (part of SQL Server Reporting Services) with important parts of the window annotated. Legend: A is the report body, an obvious place to click, and not helpful for finding Report Properties and PageSize properties. B is the design surface outside the report body; left-click here and report-level paramenters like PageSize and Margins appear in the Properties Pane, marked as C. D shows the pop-up menu which appears when you right-click on the design surface; select Report Properties… from this menu to bring up the Report Properties dialog box.
