Men's hands tend to be a bit larger from my understanding, but logically that's also due to the fact bio-males tend to have a larger structure to begin with, it's not unheard of to see a guy with girly hands though, however they normally tend to be smaller guys. Same with women, larger framed women tend to have larger hands, smaller framed women tend to have more girly hands. This isn't including things like callouses, scarring, etc that can be gained from activities. I got lucky, I'm large framed, my hands are a bit large due to it, and lets not get started on the scars and callouses collection I got.
