Characters who are at a size where it would be impossible for them to interact with would have to be scaled up in order to do so. The minimum size would be around the size of a large rat or mouse, with a maximum size being that of a normal human. We would prefer to leave the exact scaling up to the player, since part of the charm of a small character is their ability to get into places that a large character can't.

If the size of the character still lets them interact with those of normal stature, then feel free to app them in as-is! Accommodations will be made for them in much the same way as they are for the overlarge characters.
