>>25065002Gardevoir has a canon height of 5' 3" or 63 inches.
With a screenshot of the model and a little math, we can determine this.
Here, I scaled the model up to fit the grid in the background to represent its height.
Using the grid, we can measure its head as being about 1' 2" or 14 inches, a bit larger than the human average of 8-9 inches.
This means Gardevoir stands proportionally (relative to its own head) 4.5 heads tall, very different from humans who stand at about 7 heads.
Its mostly round head is also significantly wider than a human's, which is thinner than it is tall, meaning its body is actually pretty close to the thickness a young human's. Its shoulders and hips are both less than a foot wide, which is about what you can expect on a thin child.
So basically, Gardevoir has the body of a really tall loli with a freakishly large head.
