Re: the twins height, I believe elezen lore is that they get their growth spurts later than hyurs, late teens to early 20s.

Edit: Found the line from Encyclopedia Eorzea.

With lifespans one- or two-tenths again as long as their fellow races, their physical maturity is somewhat delayed. It is not uncommon for Wildwood children to look up to their Hyuran friends in their early teens, only to rapidly outstrip them around the age of twenty.
