The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth's surface, which forces scale to vary across a map. Because of this variation, the concept of scale becomes meaningful in two distinct ways
Here are four simple steps you'll want to follow:
- Find a map of an area you want to use.
- Find a map of an area you want to use.Find both the actual and measured distances of two points on your map.
- Find a map of an area you want to use.Find both the actual and measured distances of two points on your map.Divide the actual distance by the measured distance on the map for your scale.
- Find a map of an area you want to use.Find both the actual and measured distances of two points on your map.Divide the actual distance by the measured distance on the map for your scale.Place your scale numbers on the map.

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.
