It's only of late that the Mixte is becoming popular (possibly in part due to this web forum), and being recognized for what it was meant to be in the first place (unisex) and so larger frames are starting to be manufactured now.

I'm 5'll" and ride a Mixte (see sig photo) with a 20 inch seat post length, but since mine is set up as a Utility/Cruiser upright seating, and the Fuji Mixte seems to have a very laid back geometry; I don't feel the least bit cramped or confined when I ride it. As a matter of fact, when it had the drop bars on it, it felt every bit as stretched out as the larger frame Schwinn Le Tour diamond frame that I had, that was originally fitted for a person 6'3". I think the laid back position of the seat tube gives the feeling of a longer effective top tube to a great extent. Just my personal experience though.
