What's the difference between a doll and a real person's head ratio?

It depends on which one you are talking about. If it is Barbie, it is basically copied according to the proportion of people.

If it is a plush toy, the proportion of the head in the body is much larger than that of the real person, that is, the head is exaggerated.

What's more, both dolls have a common feature, that is, they exaggerate their facial features. For example, the eyes get bigger and the mouth gets smaller.
