This update is for silverleone and everyone else curious about the size of Toothless'.
I apologize I wasn't very detailed about this part, since all I put was that Toothless' head was bigger than Hiccup, but here's a better explanation.
Toothless, along with mist other dragons in this story, including the other night furies, are about forty feet tall. I felt this was more realistic as a dragon scale as dragons are stereotypically huge in mythology and legends, and I also thought it would make the relationship between Toothless and Hiccup cuter and more close.
I apologize if this upsets anyone.
