What are 3 ways of showing scale on a map?

There are three primary ways to indicate scale on a map: a representative fraction (e.g. 1:24 000) a verbal scale (e.g. “One inch to the mile”) or a graphic scale bar. Each of these can easily be added to your layout in ArcMap.

What does a map scale of 1 to 25000 mean?

The basics
