First off, no I did not make this chart. It’s official, and I believe it has been used in some promotional material or something like that from a few years ago. Second, as I already said, I don’t think this chart is that reliable because of the way they’re standing, especially Eleanor who’s crouched over slightly. So for all we know Theodore might not be 40 cm tall, but I assume it’s pretty close. It’s hard to measure their heights without anything in the show with a real-world scale to compare them to. Especially when some objects such as the cars are much larger in the show than they should be compared to the humans.
