Dimensions of Castle Walls: the height and thickness of castle walls varied from castle to castle but typically they ranged from between seven to thirty feet in thickness and typically thirty to forty feet in height. The illustration below is a cutaway view of how a typical castle wall is constructed.
The height of ramparts varies according to differing terrains. On average, the wall measures 25.6 feet (7.8 meters) high, making it difficult for enemies to break through. Usually, those built in flat areas are higher than those on steep ridges, with the highest point reaching 46 feet (14 meters).
