Dragon sizes in House of the Dragon confirmed – which is the biggest?

*Warning: Contains spoilers for House of the Dragon.*

Age: 180 years old

Size: Absolutely massive, the biggest dragon in Westeros

Rider: Prince Aemond Targaryen, the Prince Regent

Vhagar is an old gal who has seen some things. Born before the Westerosi calendar was reset by Aegon the Conqueror, she was once the dragon of Visenya Targaryen. Vhagar was eventually claimed by Leana Velaryon, wife to Daemon Targaryen.

When Laena knew she was about to die in childbirth, she walked out to Vhagar and begged to be given a death by fire. Vhagar was then riderless until she was claimed by Prince Aemond on Driftmark shortly after Laena’s funeral. Since then, Vhagar has been ridden into battle by Aemond.

Vermithor (Warning: Spoilers!)

Age: Approx. 100 years old

Size: Oh, a ginormous boy to be sure!

Rider: Hugh the Hammer

We saw Hugh the Hammer tame Vermithor in the penultimate episode of season two of House of the Dragon. Before that, we saw Vermithor toast about a dozen potential dragonriders as Rhaenyra Targaryen watched on.

There’s no telling what Vermithor will do when unleashed on the battlefield.

Sheepstealer (Warning: Book spoilers!)

Age: 80 years old

Size: On TV? Unknown. In the books? A mighty fellow!

Rider: N/A… for now.

Look, we’re not going to say too much just yet. But, if you really don’t want to know, this is your final spoiler warning.

In Fire and Blood, the book upon which House of the Dragon is based, a girl called Nettles tames wild dragon Sheepstealer.

In House of the Dragon, Nettles doesn’t seem to exist. In fact, it appears that Daemon and Laena’s daughter, Rhaena Targaryen, is going to be moved into Nettles’ position. Rhaena has been chasing a wild dragon in the Vale for a few episodes now.

We’ll leave it at that.

Silverwing (Warning: Spoilers!)

Age: Approx. 90 years old

Size: Oh, huge. Don’t mess with her.

Rider: Ulf the White (somehow)

Silverwing is one of the oldest dragons in the show and we’ve finally got to meet her! In the first episode of season two, Cregan Stark told Jacaerys Velaryon that a dragon once refused to fly beyond the Wall many years ago… that was Silverwing!

And now Ulf the White owns her. Known for being a bit of a drunkard, and for embellishing the details of his family tree, Ulf now has command over one of the oldest beasts in the land. Good luck to her!

Dreamfyre

Age: Approx. 100 years old

Size: Yep, she’s definitely a big girl!

Rider: Helaena Targaryen

Dreamfyre lives under the Dragonpit in King’s Landing. We saw her in one of the very first trailers for House of the Dragon, way back before the show had even started. We’re yet to see her in action, however, as of season two. Helaena tends not to ride her dragon much in the series.

It was implied in season two of House of the Dragon that Dreamfyre might well be the biological mother of Daenerys Targaryen’s dragons, Drogon, Viserion, and Rhaegal, from Game of Thrones.

Caraxes

Age: 65 years old

Size: Really huge! You’ve seen him!

Rider: Daemon Targaryen

Caraxes might be the strangest dragon to look at in House of the Dragon, resembling a worm rather than a dragon sometimes, but rest assured – he’s a massive unit who can burn or crush several men at once.

Daemon has ridden him into battle just once so far in the series, when he faced the Crabfeeder all the way back at the beginning of season one. Caraxes crushed a loyal soldier to death with one toe, such is his size.

Meleys (Warning: Spoilers!)

Age: Approx. 60-70 years old (dead)

Size: Huge! She was one of biggest dragons… Was.

Rider: Rhaenys Velaryon

Meleys was unfortunately caught up in one of the most tragic events of House of the Dragon thus far, when Aemond Targaryen and Vhagar dueled with Rhaenys at the Battle of Rook’s Rest. It didn’t end well for Meleys, whose neck was basically bitten in half.

Before that, she and Rhaenys escaped the Dragonpit in King’s Landing immediately after Aegon II was crowned. The common people weren’t happy when Meleys’ head was paraded through King’s Landing after her death.

Seasmoke (Warning: Spoilers!)

Age: Approx. 25 years old

Size: Large! We saw him up close!

Rider: Addam of Hull

Seasmoke was without a rider once Laenor Velaryon ‘died’ in season one. He’s been moping about in the sky and complaining ever since. He got so bored of waiting for a rider to claim him that he decided to just claim one for himself: Addam of Hull.

Syrax

Age: 35 years old

Size: Fairly large

Rider: Rhaenyra Targaryen

Syrax was the very first dragon we saw in House of the Dragon, as a young Rhaenyra Targaryen flew on her back through the clouds above King’s Landing. Since then, she’s popped up a few times, but is yet to see serious combat like some of the other dragons in the series.

Sunfyre (Warning: Spoilers!)

Age: Approx. 20 years old

Size: About as large as Syrax and Meleys

Rider: Aegon II Targaryen

Said to be the most beautiful dragon in the Seven Kingdoms, Sunfyre – unfortunately for his rider Aegon – isn’t the largest. Aegon rode him into battle at Rook’s Rest and got tangled up in a bloody scrap between Aemond and Vhagar and Rhaenys and Meleys.

The battle was too much for Sunfyre, who went crashing to the earth in a ball of flames. Much like his rider Aegon, Sunfyre is badly hurt but still alive. We might not be seeing him for a while, but the yellow dragon’s role in House of the Dragon isn’t over yet.

Tessarion

Age: 15 years old

Size: We’re getting into the smaller dragons now…

Rider: Daeron Targaryen

Now, here’s a first: Tessarion is the first dragon in this list who is yet to be shown. That’s because his rider, Daeron Targaryen, son of Alicent Hightower, is also yet to show up in House of the Dragon. But don’t worry, Tessarion is coming, if the teaser for the season two finale is anything to go by.

Vermax

Age: Approx. 10-15 years old
