first, lay a 2x4 or something flat across the nosing on one side of the
stairs.Then take a framing square and lay it on the 2x4 with the 24" end
pointing up. Slide the square up until you can make a mark of the angle on
the post at the top of the stairs (the top of the 24"end). you now have you
angle. It should be around 36-38 degrees. (verify with a speed square) Then
subtract 1 1/2" inch from the mark on the post for the 2x4 used and that
mark should also be around the right railing height.

We just purchased our home and the deck off the house was not
completed. Everything was done except the handrails. We have all the
handrails completed around the deck except for the stairs.

I was wondering if their is a standard angle for the stair railing?
Is their a formula that should be used to calculate this?

Thanks
Amy.
