Pretty sure most guy's hand don't get bigger. Not solely from T anyway. More masculine though I suppose, like tvc said.
Mine haven't grown, but I have significant hair on the backs of my hands and my veins stick out, although they've always been that way. Keeping my nails very short helps as well.
I feel like my hands are proportionate to my body/frame. I have longer fingers than most, including other guys. Compared with this tall, big, meaty-handed (lol) guy I knew, my fingers were longer even though my palm was smaller than his. So I don't feel so bad about it.
