The base is 7.4 m high and the figure on top is 12.6 m. If he could take off his helmet and boots he would probably be about 12.25 m.
How many times human size is it? The average height of a grown man in Wales is 1.77 m. If you divide 12.25 m by 1.77 m that tells you the statue is 6.92 times taller than the average man. If you round the number up, the proportion is about 7:1.
