Harry Potter, when it was released, was a global phenomenon. And not only was the movie franchise extremely famous, but so were the books that transported us to the magical world where wizards and humans seemingly coexisted for as long as civilization existed. Of course, the franchise concluded a long time ago at this point, and we know that the main characters were basically kids and teens for most of it. This is why we decided to overview Harry Potter characters’ ages, both in the movies and in real life, just to get a bit of a perspective on how much time really passed.

Editor’s Note: This post was updated in October 2023 to include additional popular characters from the ‘Harry Potter’ franchise.

How old is Harry Potter?

How did Harry Potter Come Back to Life?

In Harry Potter and the Sorcerer’s Stone, Harry Potter was eleven years old. When we say this, it also applies to his school colleagues from his year since most of the first years are eleven when they start school.

In Harry Potter and the Chamber of Secrets, he and his friends are twelve. In Harry Potter and the Prisoner of Azkaban, they are thirteen. In Harry Potter and the Goblet of Fire fourteen. In Harry Potter and the Order of the Phoenix fifteen. In Harry Potter and the Half-Blood Prince, sixteen; and finally, in Harry Potter and the Deathly Hallows, they are seventeen years old.

Most fans know that Harry Potter and J. Rolling have the same birthday and that the famous date is July 31, but the author has also revealed the birthdays of many other characters over the years. Lord Voldemort made his first attempt to disprove the prophecy when Harry was one year and three months old.

In this attempt, he kills Harry’s parents while Harry’s parents are trying to defend him, and this attempt to kill Harry resulted in Voldemort’s first Horcrux, which was the accidental one. 

Harry first attended the Hogwarts School of Witchcraft and Wizardry in 1991. Hat’s first decision was to put Harry in the Slytherin house, but Harry asked for “no Slytherin,” and the Hat listened to this request instead. Let’s remember how Harry’s decision influenced the rest of his life.

How Old Are The Characters in Harry Potter?

When James and Lily were 20 years old, they just had Harry, and when Sirius was just 21 years old when he entered Azkaban. These facts are not the easiest to grasp since we believed Sirius was much older.

When Harry first arrived at Hogwarts, Hagrid was 63 years old, while Snape was just 31. According to the Harry Potter fandom Wiki, Lupin and Tonks married in 1997, making Lupin 37 years old and Tonks 24 years old. Tonks attended the same school as Charlie Weasley, but she graduated only a few months before Harry.

James and Lily probably married and had Harry at a young age because of the first war against Voldemort, which is not strange. Of course, it was only because of their deaths and Lily’s sacrifice for Harry that their story ended so suddenly.

Tonks most likely decided to marry Remus as soon as possible during the second Voldemort war for the same reasons. Remus’s condition had kept him from finding a partner, let alone having a wife and child.
