Six miles from side to side (face to face), to take advantage of the benefits described here:

One question I'm still unclear on is the subdivision of hexes. I've seen some templates where there is a sub-hex centered within the larger hex and others where they are offset, leaving a vertex at the center of the larger (parent) hex. Is there any reason for one method over another? Other than stylistic choice?

I'll disagree with one point in that link you have. 60 or 600, etc, would divide as easily as 6 will, so don't think you're bound to 6 miles. Taking the 60 example, red becomes 60, blue becomes 70, and green becomes 35. Otherwise, it has great logic to it.

I believe it has more practical purposes than style points, particularly for ease in going from world size > region > local area. This link is an example of a sub hex centered and the geometric measuring possiblities coming from it.

Here's a different example of subdivided hexes. On the 6 mile scale, it may be too much detail for you for sub-measurements.

On a larger scale, sub-divided hexes may be a good idea; it's only my opinion, so do with it what you will. In the end, if it works for you, use them, if not, don't. But I'd like to see what you wind up with in the end.
