Can I ask a question? I'm curious? What's the Storm King's height? Because I'd been trying to research him, but they didn't even say anything about his height. I know ponies are four feet tall (in my theory) from the head, but can't tell how tall he is. What do you think?

A good place to start would be to compare him to other characters. Firstly, let's find out how tall ponies are compared to humans...

Done. Now compare pony Twilight's height with Tempest...

...and then we compare her height to the Storm King's...

...and I guess you can figure out the rest from there.

Between 10-12 feet tall. That's like as tall as an African Elephant.
