My gaming campaign's idea of dwarves changed over time due to various player characters, especially with a homebrew character-building system that started out as "Make original D&D fairer and less silly" and ended up closer to the Hero System build-your-own-character rules, but with a lot of GM influence: You could build a character your way in general, but they had to fit into the campaign style, stay within a certain range of stat/power limits, not crowd another player character's main specialties, and be someone the rest of us could both like and respect.
(I did run a GMPC so I could be in in-character group discussions, etc., but my GMPC was usually the lowest-powered character and mostly used for two things: covering major gaps in the group so that, for example, if nobody else wanted to run a healer, we weren't always up wound creek without a paddle, and asking those questions like "Gee, mister, where did you get that scar?" to make sure even the shyest & quietest gamers got included in things.)
By and large, though, my campaign's dwarves were usually between 3 1/2 to 5 feet tall, pert' strong & sturdy, and the sort of stubborn buggers who'd try to rip their enemies' throats out with their teeth if they ran out of weapons and sharp rocks. As one of my gamers put it, "Both sexes are macho."
