Hiccup is a fictional character from the “How to Train Your Dragon” franchise created by Cressida Cowell. He is the main protagonist of the series, and his age varies depending on the media in which he appears.

In the original book series, Hiccup’s age is not explicitly stated. However, it is implied that he is around ten years old in the first book, “How to Train Your Dragon.” In subsequent books, he appears to age at a normal rate, and by the end of the series, he is likely in his late teens.
In the film adaptation of “How to Train Your Dragon,” released in 2010, Hiccup is depicted as a scrawny, awkward teenager who is around 15 years old. The events of the film take place over the course of several months, so by the end of the movie, Hiccup would be around 16 years old.
The film was followed by two sequels, “How to Train Your Dragon 2” and “How to Train Your Dragon: The Hidden World.” In these films, Hiccup ages from a teenager to a young adult. In “How to Train Your Dragon 2,” which takes place five years after the first film, Hiccup is around 20 years old. “The Hidden World” takes place about a year after the second film, so Hiccup is around 21 for most of it; its epilogue jumps ahead several years and shows him as a father. The 2025 live-action remake of “How to Train Your Dragon” retells the first film, so Hiccup is a teenager again there.
In addition to the films, Hiccup has also appeared in several television series and video games. In the television series “Dragons: Riders of Berk” and “Dragons: Defenders of Berk,” which take place between the first and second films, Hiccup is still a teenager and is likely around 16 or 17 years old. In the later series “Dragons: Race to the Edge,” which takes place before the events of the second film, Hiccup is around 19 years old.
Overall, the age of Hiccup varies depending on the media in which he appears. In the original book series, he ages at a normal rate, and by the end of the series, he is likely in his late teens. In the films, he is a teenager in the first movie, and he ages into a young adult in the sequels. In the television series, his age ranges from his mid-teens to early twenties.
