How Long Is the Great Wall of China in Miles?

In totality, the length of the Great Wall of China is 13,171 miles long. This includes the 5,500 miles of wall built in the Ming Dynasty in the 14th century.

Construction of the Great Wall of China began in the eighth century B.C., but it wasn't until the fortifications of several smaller walls were united in the Qin Dynasty that the wall became known as "changcheng," meaning "long wall." The early walls were created with a rammed earth technique. In the 14th century, brick and stone were used to build the wall. The Great Wall is comprised of 3,889 miles of actual wall, 223 miles of trenches and 1,387 miles of natural barriers, such as hills and rivers.
