Heh. In any case, the point being, people regularly don't really conceptualize just how small Small is. Just to use a good example, an Eagle is a small animal. Now, sure, an eagle is a bloody big bird, but, it's really not very big compared to a fully grown human. I think people picture Gimli as small. He's really, really not. See, even the Hobbits in the movies:
are WAYYY bigger than a D&D halfling. Look at Bilbo there. ((This was what I found after a 30 second Google image search - I'm sure there are better examples). But Sir Ian here is 6 feet tall. That hobbit is over four feet. Bilbo is a freaking GIANT halfling. He should be, by D&D stats, about a foot shorter. The top of his head should be below Gandalf's belt line. In D&D terms, Beorn is medium, and that would make Bilbo about the right relative size.
Actually, this image from Wikipedia:
Shows it even better. All the Hobbits, in D&D terms, are medium. Note, they're barely shorter than Gimli who's supposed to be 5 feet in D&D terms. The Hobbits, again, in D&D, are about a foot shorter than they are pictured here. Small is REALLY small.
