Working with legend patch shapes

Legend patch shapes are the geometric shape of either a line or a polygon that is used to represent a specific kind of feature in a legend or in the table of contents. You can choose to use any of a variety of predefined legend patch shapes in ArcMap.

Different legend patch shapes may be more appropriate given the type of data you are representing in your maps. For instance, natural features, like lakes or ponds, have amorphous shapes, and often, it is cartographically more appropriate to represent these features in a legend with such a shape rather than a rectangle.

The table of contents can be set to use a specific patch shape for all line and polygon layers.

Legends in ArcMap can be set to use specific shapes for each layer or even a set of features that fall under a different heading when the unique values symbology method is used.
