Map of Westeros is made in vintage style, it depicts a continent ruled by the King of the Andals and the First People.
Westeros is not the only continent in the world of the Game of Thrones, but it is located west of the second continent and they are separated by sea. In general, on three sides, Västerås is washed by three seas: the Sunset Sea from the west, the Narrow Sea and the Shivering Sea from the east, and the Summer Sea from the south.
From south to north, the length of Westeros is about five thousand kilometers (meaning only the distance to the Wall). The width of the continent is much smaller and is approximately one and a half thousand kilometers.
