Westeros is 1.15 times as big as United States (Contiguous)
Westeros is a fictional continent from the Game of Thrones TV series. The elongated continent is roughly the size of South America. The continent is home to the Seven Kingdoms, also known as "the Realm" or the "Sunset Kingdom", located to the south side of the Wall, a massive man-made ice wall (allegedly fused with magic) 700 feet in height and spanning east–west for 300 miles from coast to coast.
The contiguous United States (also known as the lower 48 or the conterminous United States) consists of the 48 adjoining U.S. states (plus the District of Columbia) on the continent of North America. The terms exclude the non-contiguous states of Alaska and Hawaii, and all other off-shore insular areas, such as American Samoa, U.S. Virgin Islands, Northern Mariana Islands, Guam and Puerto Rico.
