Discussing this before with our coffee lover, I come to say she would be about the size where she could rest on Annaliese's shoulder or head.  I consider I have a forearm the length of an average human, I've come to think that she is about as tall as the bottom of my elbow to the bottom of my wrist.  Holding it vertically up that is.  Approximately a foot in our silly American measurement system, give or take a few inches.  That's how I've been imagining it.  So she not really too small, but she not really big at all either.  OH I think of her as an adorable teddy bear. If that helps.
