House of the Dragon is finally here, and it promises to show at least 17 dragons throughout its runtime. Set two centuries before the events of Game of Thrones, the HBO show transports audiences to a Westeros where dragons reign with the formidable ancestors of Daenerys Targaryen.
The Targaryens have a history of dragonriding, and it is during the reign of King Viserys I (Paddy Considine) where the dynasty had the most fire-breathing beasts Westeros had ever seen. We know from George R.R. Martin source material that dragons keep growing as they age – so the older the dragon, the bigger it will be.
In Game of Thrones, Daenerys’ mount Drogon was enormous by Season 8. Fans have predicted his wingspan was around 60m (196ft) – and he was only around seven years old. Some of the beasts in House of the Dragon (HOTD) are more than 100.
However, something that restricts the size of dragons in this universe is captivity. By the time of House of the Dragon, most of the Targaryens’ dragons live in the dragonpit, a huge stable in Kings Landing. But, it is thought living in chains restricted the dragons’ growth, and they became smaller over the centuries. Wild dragons, and dragons which have fought battles, meanwhile, grow much larger. With that in mind, here is a guide to the major dragons which will feature in House of the Dragon, from biggest to smallest.

9. Sheepstealer
Sheepstealer is a wild dragon who lives on dragonstone and feasts on livestock. As he is wild, he is thought to be larger than many of the other dragons who have spent their lives in the dragonpit. Photo: HBO

10. Syrax
Princess Rhaenyra’s dragon Syrax is around 40ft (12m) long at the start of the show, though she will grow as time goes on. Thought to be around the same age as the princess, the she-dragon is kept in chains and rarely hunts for her food, which may restrict her size. Photo: HBO

11. Grey Ghost
The smallest of the wild dragons living on Dragonstone, Grey Ghost is a shy and elusive creature who has never been ridden. Being a wild dragon, he is thought to have reached a considerable size. Photo: HBO

12. Sunfyre
Sunfyre the Golden belongs to King Viserys and Queen Alicent’s son Aegon. The beautiful golden and pink dragon was hatched on Dragonstone, though his age is unknown. In the Dance of Dragons, he is on track to be one of the largest dragons who ever lived. Photo: HBO
