Grids can be added to a map frame to show coordinates and divide the map frame. There are four types of grids that can be added to a map frame: graticules, measured grids, MGRS grids, and reference girds.
Graticules are lines showing parallels of latitude and meridians of longitude for the earth. They are used to show location in geographic coordinates (degrees of latitude and longitude).

A measured grid is a network of evenly spaced horizontal and vertical lines used to identify locations on a map. They are used to show location using projected coordinates.

A Military Grid Reference System (MGRS) grid is a special type of measured grid. It is used to show locations in a UTM coordinate system and display MGRS specific information, such as 100,000-meter grid designators.

A reference grid is a network of columns and rows used to divide a map into equal-area rectangles. They are used to visually divide the map, independent of the coordinate system, to allow simple location referencing.
