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?
