I'm 5'4" and never was called short or anything like that. However, I'm asking because my 2-year old daughter is measuring at the 3rd percentile for height (she's only 80cm tall - 31.4 inches)...And apparently whatever height they are at 2-years, if you double it it will give you their adult height (anyone heard of this?).

That gives DD an adult height of 5'2" at best.
