Add a grid
There are five types of grids that can be added to a map frame in a layout: graticule, measured grid, MGRS grid, reference grid, and custom grid. You can also combine grid types to display multiple coordinate systems on the map. For example, you can display a Universal Transverse Mercator (UTM) measured grid and a graticule on the same map frame, each symbolized differently.

Graticules, measured, MGRS, and reference grids are all added by selecting a grid from a gallery. By default, the gallery is populated with basic graticules, measured, MGRS, and reference grids. If your project contains a style with grids, those grids will also be available in the gallery. Custom grids, however, are based on a polygon or line layer in the map frame and are added differently than other grid types.
