If you open up the Apple Store app, you can take a look at the two different watch sizes in actual size so you can decide which size is best for your wrist. If you need a little more help still, MacWorld has a guide that breaks down the absurd number of options you have to choose from as well. Apple's also put together a sizing guide for the different strap sizes. You have until the April 10th preorder date to make your decision (or talk yourself out of buying one), but you can get a head start now if you're into it.
