It's amazing the things we notice when we rewatch things. Fantasy shows like "Game of Thrones" are especially fun for that but also a bit frustrating. Unlike realist dramas, they create their whole worlds from scratch; yet unlike sci-fi, the worlds are supposed to feel familiar.

The world of "Game of Thrones" is clearly supposed to feel a lot like Britain. This is partly due to Hollywood's tendency to declare that anyone carrying a sword should have a British accent. But that's an illusion. Based on a few clues dropped in the show, we learn that the fictional land of Westeros is actually quite a bit bigger.

In the Season 1 finale, we hear a man telling a group of people leaving the city of King's Landing that "it's a thousand leagues from here to the wall." A thousand leagues is about 5,000 kilometers — more than the distance from, for example, New York City to the equator. Plenty of space for some significant changes in climate.

As for how they cover these distances on horseback, we have the miracle of TV storytelling to thank — viewers get to skip over the boring parts.

In the very first episode of the show, the Queen, having just travelled from King's Landing to Winterfell, says, "We've been riding for a month." So, yes, they do make these sprawling trips on horseback, but they are kind enough to not make you watch.
