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 Wall is a massive barrier of mostly ice stretching across the northern border of the Seven Kingdoms, separating it from the wild lands beyond. The Wall is one hundred leagues long (three hundred miles) and reaches over seven hundred feet at his highest point, although some foundation blocks in hilly regions, such as near Greyguard, send it nine hundred feet in the air.
