As a really general guide, heavier denim will probably stretch less. But that's very general. What matters more is the tightness of the weave of the denim. Unless you're told explicitly about the tightness/looseness, it's hard to say how much it'll stretch. e.g. my 14oz PBJ 005's stretched WAY more than my 21oz IH 634s (3 inches versus 1.5).
