I bought the latest X-men Encyclopedia, and it says JEAN is 5'8". In the 90's she was depicted as 5'6", and in the 60's-early 70's, she was depicted as 5'4". I also have a Fleer card stating Jean's height is variable as Phoenix. She's always portrayed as being slightly shorter than Storm, but still relatively tall. After all, she was once a runway model. I think it is fair to say that she can be considered a relatively tall woman. Famke is 5'11, so who knows what Jean's real height is. In my world, I picture her as the same height as EMMA, so about 5'1O" as far as I am concerned, which makes sense for Jean's modeling career.
