A variable scale for measuring maps

A map scale is the size of an object compared to the size of the object's smaller representative on a map. This can be shown by a scale bar and a ratio 1:n. The reader can measure a distance on the map to know what is the distance on the ground.

People sometimes speak of a map as one with a "large scale" or "small scale". A "large scale" map makes things look large, and a "small scale" map makes things look small. For example, an island displayed on a 1:10,000 map will appear larger than if it were displayed on a 1:25,000 map. Thus, the former is "large scale". What can be confusing is that for a map of a given physical size, say 11 by 17 inches, a "large scale" map will have a smaller geographic extent than a "small scale" map centred on the same point.

Maps with a ratio of 1:50 000 or larger (for example, 1:40 000 would be larger) are considered large scale. Maps with a ratio of 1:50 000 to 1:250 000 are considered intermediate scale. Any maps with a smaller scale (for example 1:300 000) are considered small scale.
