A Knight of the Seven Kingdoms: How tall is Ser Duncan the Tall?
In "A Knight of the Seven Kingdoms" there are constant jokes and references to Ser Duncan's height. But how tall is he in the story, and how tall is Peter Claffey, who plays him?

To be known as "The Tall" you'd have to be pretty tall, but how tall, exactly, are we talking?
This may not be your biggest question after watching A Knight of the Seven Kingdoms, but we're willing to bet it's crossed your mind.
The show includes multiple mentions of everyone's favourite hedge knight, Ser Duncan the Tall (Peter Claffey), being of large stature. But how tall is the character in George R.R. Martin's Dunk and Egg books, and how does the actor playing him measure up?

Despite there already being numerous jokes and references to Dunk's impressive height — "The Seven above gave you tallness!" says Ser Lyonel Baratheon (Daniel Ings) at one point, after commenting on Dunk slouching, "So be tall!" — we don't know exactly what that impressive height is. Ser Duncan towers over pretty much all the other characters he meets, but how tall is he? Are we talking the Hound's height? The Mountain's? Taller?
Fortunately, we have George R.R. Martin's books as a reference point. In the Dunk and Egg series, Ser Duncan is measured as being an inch shy of seven feet. So, canonically at least, the character is 6'11'' tall.
How tall is Peter Claffey, the actor who plays him?
There aren't many actors out there — or people in general — who are 6'11'', so it's perhaps unsurprising that the onscreen Dunk isn't quite as lofty.
Former rugby union player-turned-actor Peter Claffey is a large man, though, with his height listed as 1.95 meters, or around 6'5''.
In other words, he's about six inches shorter than the Dunk Martin envisioned in his books. But when you're still towering over almost every other person around you, maybe it doesn't matter all that much.
