How big is Smaug?
In The Atlas of Middle-earth by Karen Wynn Fonstad, Smaug is said to be about 18 meters (59 feet) in length, but this is to be considered non-canonical. Is drogon bigger than Smaug? Drogon Daenerys Targaryen's mount from Game of Thrones, ended up being 50 meters long, plus or minus 10. Smaug from The Hobbit is a staggering 140 meters long, give or take 15. King Ghidorah from Godzilla dwarfs them all at 158.
