When HBO premiered Game of Thrones in 2011, viewers met Daenerys Targaryen as a terrified exile being sold into marriage by her abusive brother. The stark contrast between her fragile beginnings and her explosive rise to power left millions wondering how old she actually was. The television adaptation made specific changes to aging up its characters, creating a lasting debate among fans who compare the HBO series to George R.R. Martin's original novels.
In the television series, Daenerys Targaryen is approximately sixteen years old at the start of season 1. Meanwhile, her book counterpart begins the story at just thirteen years old. This adjustment was a deliberate choice by showrunners David Benioff and D.B. Weiss to navigate sensitive thematic material and make the actors' ages more fitting for adult television production. Understanding this distinction clarifies how time moves across Essos and Westeros during the early conflicts of the realm.
The Television Adaptation: Aging Up Daenerys
When casting the pilot episode, the production team faced the challenge of translating George R.R. Martin's dense text into a visual medium. In the show, actress Emilia Clarke was twenty-three years old during filming, though her character was written as roughly sixteen.
This sixteen-year timeline is established through dialogue and contextual clues across the first season. Unlike the novels, which rely on internal monologues and explicit numeric tracking by the author, the television medium uses character interactions to ground the narrative. By making Daenerys sixteen rather than thirteen, the series avoided certain production hurdles and aligned viewer expectations closer to mature historical drama conventions.

The Source Material: George R.R. Martin's Timeline
In A Game of Thrones, the first book in the A Song of Ice and Fire series, Daenerys starts her journey at thirteen years old. Her brother, Viserys Targaryen, marries her off to Khal Drogo in exchange for an army of Dothraki screamers to reclaim the Iron Throne.
George R.R. Martin originally conceived a multi-year time jump between his second and third books, which would have naturally aged up all the younger characters. When that structural plan fell through, the ages of characters like Daenerys, Arya Stark, and Jon Snow remained remarkably young during the initial conflicts.
- Daenerys Targaryen: Age 13 at the start of the books, turning 14 during her first year with the Dothraki.
- Viserys Targaryen: Roughly twenty-two years old, serving as the volatile nominal head of House Targaryen.
- Jon Snow and Robb Stark: Both begin the narrative at fourteen years old in the text.
How Time Moves in Season 1
The events of season 1 span roughly one year of in-universe time. Daenerys undergoes a rapid psychological and physical transformation during this brief window. She transitions from an obedient, frightened girl hiding in Pentos to a confident Khaleesi who commands the respect of bloodriders and eats a raw horse heart in a sacred ritual.
By the end of the season, following the tragic death of Khal Drogo and the miraculous hatching of her three dragon eggs, she is roughly seventeen in the show's continuity. This accelerated growth isn't biological aging; it's a testament to the brutal trials forced upon her by Westeros and Essos politics.
Common Misconceptions About Targaryen Ages
Fans frequently confuse the chronology of Westeros because of the complex Targaryen family tree and historical flashbacks. Here are a few frequent points of confusion that derail timeline discussions:
- Conflating Book and Show Canon: Many viewers assume Emilia Clarke's character was thirteen on screen, forgetting that HBO explicitly aged up nearly every minor character to avoid casting child actors in mature scenes.
- Assuming Dothraki Customs Dictate Age: Some online theories suggest nomadic lifestyles caused accelerated physical maturation. In reality, the physical maturity depicted on screen belongs entirely to the casting choices of the production crew.
- Misreading the Aegon's Conquest Era: Viewers sometimes mix up Daenerys' age with historical figures from Fire & Blood, such as Rhaenys or Visenya Targaryen, who conquered Westeros centuries earlier at different life stages.
Frequently Asked Questions
Why did the showrunners age up Daenerys?
The creators raised the ages of several young characters in the adaptation to make the casting pool wider and to handle adult thematic elements responsibly for a mainstream television audience.
Does George R.R. Martin regret the original character ages?
Martin has occasionally noted in interviews that starting his characters at such young ages created logistical challenges for long-term storytelling, particularly when he abandoned his planned five-year gap between books.
How old is Daenerys by the final season of the show?
While the show never explicitly states her exact birth year in later seasons, timeline approximations put Daenerys in her early-to-mid twenties by the time the series concludes.
Did Emilia Clarke's age match the character throughout the series?
Emilia Clarke was in her mid-to-late twenties during the middle seasons of production, meaning the actor was significantly older than her character for the majority of the show's run.
