When a dashboard is created in the Dashboard Builder, the Builder specifies a width and height for the dashboard. You can resize Dashboard Viewer windows, but the aspect ratio of width to height cannot be altered. If you resize a window to a different aspect ratio, the window size will automatically be adjusted in order to maintain the aspect ratio specified in the Builder.

When you resize a Dashboard Viewer window, the objects within it are scaled in order to maintain their size relative to the size of the window. Scaling allows dashboards to be enlarged in order to allow greater detail to be displayed, or reduced so that the dashboard occupies a smaller area of the screen.

When a dashboard Window is reduced in size, objects such as charts will scale all their visual elements in order to maintain proper appearance at the new size. Other objects, such as tables and input controls, adjust their width and height but may not scale all their visual elements, such as fonts in table column headers.
