Will my SIM card fit into an iPhone 5?

I'm getting an iPhone 5 tomorrow from T-Mobile after having the same phone for two years. My phone now, a Motorola Cliq 2, is on its last leg and hasn't been working well at all (randomly turning off, freezing while I'm texting, taking me to different applications when I haven't clicked them, etc) and I've been wanting a new iPhone for awhile and I'm finally going to get one for myself as a graduation present.
My question is, will my SIM card fit into the iPhone? I'm concerned about this because I don't want to lose all my contacts and have to ask people for their numbers and all that, so would my SIM card be able to fit into an iPhone?
