I've been wondering this cause my hands and wrists are so thin and feminine. I've heard that T makes your feet bigger/thicker so could it do this to your hands too?

Yes, the muscles become more obvious, as do the veins. It decreases the fat (although doesn't sound like that's your problem) and increases the muscle. Also makes the skin less soft, and they can get hairier.

From what I've heard, the hands (bones) don't actually grow, but they do tend to lose their soft feminine look.  I think more prominent veins and hair growth on the sides of hands by the wrist would contribute to this.  If you want to make your hands & wrists slightly more masculine pre-T, I would recommend taking up weight lifting.  I've been weight-lifting for 4 years and my hands do look less soft.  There are now visible veins on the back of my hand where there were none before.  Tendons stick out when I move my fingers, which I never had before, either--however, I lost a fair bit of fat so this could be why the 'inner workings' of my hands are more visible now.  Forearm exercises have made my forearms somewhat thicker-looking.  I really don't recall if the forearm exercises made my wrists look all that different, though.  They're 6.25" in circumference now, but I don't recall measuring them before starting lifting.  The difference probably isn't going to be dramatic, but if it makes you feel better about yourself it's worth it.

I haven't been seen any prominent veins just alot hairier.. no bigger at all, just more rough!

Been on T 9 months..

Thanks guys. Actually I've been doing weightlifting casually for the past month or 2, and my wrists have gotten a teeny bit thicker, and veins are starting to show a little on my forearms (that might be wishful thinking haha). I saw a huge difference in my upper arms though. But my hands are still soft as ever. I guess I was blessed with a more male body shape in general tho.. but I think most of the estrogen is going to my hands. lol

Lifting definitely helps. I started working out maybe eight months ago, now you can see clear veins/tendons on my wrists/hands.

I like the way the veins (on my hands at least--I don't have any highly visible veins anywhere else) bulge out when doing a lot of lifting with my arms.  It's a little creepy, though... kind of makes me wonder what would happen if the top of my hand got cut while the veins were dilated like that.  I don't think it'd be good.

my hands deff. changes alot veins stick out all over the place lol though im not very hairy still very masculine ....

I've been on T for about 6 months and my hands and feet both have got bigger. I think my hands have got bigger width wise I would say, I had to buy new winter gloves because my gloves from last year didn't fit anymore. I do work out a lot so I'm sure that has some to do with it.

The wrist and hands would be a great bonus to my structure.  I lift weights and still have stick arms!

However, the feet part I DON'T want.  I already have a HUGE foot.  If it gets any bigger without me getting taller I might as well join the circus!

Whilst not knowing your age ( re. bone growth pending etc ) I would imagine that the only increase in size would be muscular and vascular in combination.  Though born a boy, my hands remained small and my feet tiny for my gender at adult male stage. 

I look foward to see what happens to my hand and feet once full strentgh HRT begins though.
