Hmmm, not sure about "bigger" per se.
I've always estimated him about 8x5-9x6 (being very generous), but the most deceptive factor about him is his extremely low body weight for his height (probably 140-150 lbs. max for being taller than 6 ft.)
So bigger, probably not since he's already at the highest end of the spectrum. Similar size, sure there are plenty.
