 Umm...except for Ruffnut and Heather! No I am fairly certain that he is older than Thirteen. Possibly Fourteen at the absolute youngest, but I would still say the evidence points to him being older. How many thirteen year olds are anywhere near as mature as Hiccup or Astrid? They intentionally made them young adults (as stated in the art of how to train your dragon book). They are not really children anymore, but they are not adults either. They are kind of in those middle teen years, so I would guess fifteen (of course fourteen might be correct but still.....)



 Think of it this way. Do they act like middle or elementery schoolers? Really probably not. Do they act like a group of High Schoolers? Yes in many ways. Even the kind of gang or team friendship mentality seems to reflect a slightly older teenager. All the hassle over many of the emotional problems they come across would be very odd for a younger teenager to feel.



 Now it is ABSOLUTELY possible that I could be reading the evidence wrong and you could be completely correct. Still I think if you pay close attention to ALL the teens you will get an older feel than fourteen. Why else would SNotlout be moving back into his parrents basement? All sorts of little things like that hint at their age.
