Abstract: A method, system and computer usable medium are disclosed for managing the display of content elements within a predetermined display area of a user interface. Content requests are submitted from a browser to a content server. In response, the content server acquires candidate content elements for display within the browser. A content element manager determines the dimensions of a target display area within the user interface (UI) of the browser. The content element manager then determines the space required to display each of the candidate content elements. Calculations are then performed to determine the maximum number of content elements that will fit within the dimensions of target display area. Once determined, the content elements are selected and displayed in the display area.
