The story takes place primarily on a continent called Westeros, which is roughly the size of South America.
The continent is home to the Seven Kingdoms and lands beyond the great Wall, which makes up a large chunk of Westeros, being roughly the size of Canada, with most of it largely unmapped and unexplored.
