When my first B. smithi was 2 inches, I was able to accurately sex him from a molt. I think around 2 inches is where the sex organs become defined enough to differentiate them in the shed exuvia with naked eye. As for outward appearance, I think they need to be around the 3 inch point to identify accurately.
(I caveat this with 3 inch for me, perhaps other more experienced keepers can differentiate at a smaller size)

If you can get a molt in decent shape, it should be fairly obvious at that size. Sexing by molt is by far the easiest method... providing that the T will cooperate.

I find Brachypelma species easy to sex externally by about 2", then again, it's the genera I'm the most familiar with so go figure

By that size the females have the beginnings of the sclerotized epigastric furrow and generally larger chelicerae, males have a tell tale dot in the center of the furrow but no other changes to it.

The dot:

Well, dookie, it doesn't look like we can link to pictures on the board now

Go to this thread to see the dot I'm talking about for males.
