Can any builders tell me how far their stair nosing overhangs? I've read that 1.25" is common.
I'm having my stairs rebuilt and the overhang will affect the location of the bottom stair. Also, do you include the overhang amount when measuring the run of the stair? My stairs are going to be 8.1" tall due to lack of headroom and if the run is too long they will not be within the inch of (2X rise)+run=25. I want to make sure I'm measuring the run correctly so they are comfortable.

1" to 1-1/4" is fairly standard regardless of location, but it's mostly personal preference. You don't normally consider the nosing when working out rise and run, as they typically only apply to the stringers (which have no nosing).
Even if the nosing was considered, the rise and run don't change since you'd measure from one nose to the next.
