Scale-based label sizing is applied to a map by
setting appropriate text symbol sizes for labeling at multiple scale ranges. It
is often necessary to build scale-based label sizing to enhance data
presentation on the maps, as it reduces visual density at smaller scales while
retaining appropriate relative sizes at larger scales. This video shows how to
create scale-based label sizing in ArcGIS Online Map Viewer by adjusting the
text symbol sizes and the visible scale ranges for the labels. Item 31317-2024
