What is the difference between large and small scale maps?

Published in Map Scales 3 mins read

The primary difference between large and small-scale maps lies in the area they represent and the level of detail they provide.

Understanding Map Scales

Map scale refers to the ratio between the distance on a map and the corresponding distance on the ground. It's crucial for understanding how much the real world has been reduced to fit onto the map.

Large Scale Maps

  • Focus: A large-scale map represents a small geographical area, like a city neighborhood, a park, or a single building.
  • Detail: These maps showcase a high level of detail. You'll find specific buildings, street names, individual paths, and other fine features.
  • Use Cases: Large-scale maps are used for navigation within small areas, city planning, and detailed geographical analysis.

Small Scale Maps

  • Focus: A small-scale map represents a large geographical area, such as a continent, a country, or an entire region.
  • Detail: These maps show less detail. They are used to give a general overview of large areas. Individual buildings, specific streets or small parks are typically not displayed.
  • Use Cases: Small-scale maps are used to show global patterns, such as climate zones, political boundaries, or major transportation routes.

Practical Insights

  • As the provided reference highlights, maps, regardless of scale, are valuable tools for developing spatial thinking skills.
  • Choosing the correct map scale depends entirely on the purpose for which the map will be used. If you want to find a specific building on a street in a city, you need a large-scale map. If you want to see the overall size of a continent, you need a small-scale map.
  • Remember that "large scale" refers to the ratio being large, leading to a large representation of detail over a smaller geographic area. Similarly "small scale" refers to a smaller ratio where a small amount of detail represents a large geographical area.
