The image and text description in a girl's profile represent the median for their species so realistically, any monster could take on any form, be it big, small, wide, or thin. As a result, adding a new "Body Type and Size" attribute to every profile wouldn't represent any canonical info.

The reason you can search by things like diet and habitat is because all of that information is included directly in the profile and comes from the author, therefore marking it canon.
