>too big to be real, small enough to interact with normal size people.
seems to be around 1.33-1.50
1.33 - 2.5 heads taller - reference person's head just below bust
1.50 - 3.5 heads taller - reference person's head just above navel
if you start 'unrealistic' earlier:
1.27 - 2 heads taller - reference person's head at chest height, eye-level with nipples
1.25 - still borderline realistic
if you extend 'normal size people interaction':
2.0 - 7 heads taller, reference person's head under navel
2.5 - reference person's head just below loins
3.0 - reference person's head ends at mid-thighs
4.0 - reference person's head below knee. (still 'mini' giantess ???)
