If you were to measure all the sections ever built, a new reports suggest the Great Wall of China could be a staggering 13,170.7 miles long. The most popular (and arguably the most beautiful) section was erected during the Ming Dynasty, and runs for 5,500.3 miles between Hushan to the Jiayuguan Pass. Even if you only take into consideration the main-line length of the wall (about 2,150 miles) it’s still the record-holding longest wall in the world. The whole project of the Ming Great Wall took more than 200 years to complete, and there were 18 large-scale constructions of the Great Wall in the Ming Dynasty. After that, the total length of the Ming Great Wall was more than 7,000 kilometers(3,720 miles) from Yalu River in Liaoning Province in the east, to Jiayuguan Pass in Gansu Province in the west. It passes nine cities, provinces and autonomous regions of Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Shaanxi, Ningxia and Gansu.
For those wondering how tall the Great Wall of China is, the general answer is that the structure’s height varies considerably, from 15 feet all the way to 39 feet. At its widest point, the wall is 32-feet-thick.
