Besides head size, it matters with body size too. Proportionately, I have a DP '95, and that actually fits perfectly with my skinny frame. If I had a much larger helmet, I think it would be way too large vs. my shoulder width. Yes, I know that the movie helmets did look kinda bobble-heady on Jeremy Bulloch in some stills we've seen, but I've had enough people tell me my helmet fits my frame really well, so take those sorts of things under consideration as well.
