And here we have yet another stellar example of What Nerds Do On Their Days Off. I’ve heard a lot of speculation lately about Hiccup’s height in the sequel (specifically about him being way, WAY tall now), and I have to admit it got me pretty curious, so I decided to see if I could help set the record straight and photoshopped a still from the trailer to put Hiccup and Toothless side by side.
According to what we know, Toothless is around 10 meters long (a little more then 32 feet). Assuming that he hasn’t grown too much length-wise, this would put Hiccup somewhere between 2.2 to 2.25 meters tall, or somewhere between 7'2" and 7'4".
Of course, these measurements are only relevant if;
a) Hiccup and Toothless are in scale with one another in this screencap (it’s a pretty safe bet they are, but you never know, really).
b.) Toothless' length is measured from the tip of his nose to his tail fin (For the sake of curiosity, I did measure it from nose-to-tail, minus the fins as well. Hiccup was 2.5 meters, or 8'4" O.O).
c.) Toothless hasn’t grown length-wise (Which would again mean Hiccup is actually taller then the 7'2" minimum).
