Fran is only slightly shorter than my female elezen, who is at max height. Another said she's about as tall as their mid height female elezen. Most NPCs, even including the major ones, are at the 50 mid (default) height. Further since Fran's an early Viera model, its even more likely she's at the mid (default) height. This makes Viera around female elezen height. Even the smallest female elezen is taller than the tallest midlander.
