>>1121868323-4 inches is great for tiny companion frustrated at size difference but loving you anyway, able to be picked up and held but you have to be gentle with her
10-13 inches is better for fug, basically barbie doll sized, still able to sit on your shoulder and be held but not as delicate
any size between those is fine
any larger and the fairy starts to edge into elf territory
any smaller and the fairy is going to have too much difficulty loving you
