When you create a new dashboard, you choose a default layout up front. That choice carries through to any new rows or tabs that you add. There are two layout modes.
+ **Auto grid** – Set a minimum column width, row height, and maximum number of columns per row. Panels resize automatically to fit the screen. This mode works well for dashboards viewed across different screen sizes.
+ **Custom layout** – Size and position each panel manually, by using a drag-and-drop grid.

You can change the default layout in the dashboard settings at any time.
