Based on Scale maps are two types.
Large scale maps
Short scale maps

It shows small areas in greater detail because they are drawn on a relatively large scale.
Cadastral maps are village and town maps.
Topographical maps show smaller areas in much greater detail about the small areas.
Small scale maps:
It shows large areas like continents or countries.
These maps are drawn on 1 cm = 1000 km. These are called small-scale maps.
Wall maps are small-scale maps showing large areas.
