Speculations How much maximum size Dragon Woki weight?

#15
If we use the body proportions of a stegosaurus, and assume that one of Nidhoggr's spikes is 1/15th of his body length, and that a spike is 10 times longer than an average giant (20 meters), we get a body length of 3 km or 1.85 miles. A stegosaurus is stated to have been 6.5 meters long and to have weighed about 4 metric tons on average; since weight increases by the cube of length (assuming constant density), that's roughly 400 million metric tons.
