Mini-giantess

By convention of the GTS community, mini-giantess are women whose size ranges from 3 meters up to 9 meters.

In this case, these women can not exist in real life because of the laws of physics (such as square-cube law) and biology. Therefore, from this size and upwards, the giantess are considered fantastical in nature (i.e. "they are nothing more than fantasies").
