Consider climbing out on a 12ft or a 16ft long joist that's 3 inches deep, smaller than a 2x4. Notch it imperfectly with a portable saw, as one does, and it's more like a 2.5" 2x3. I eventually realized that the only thing holding those stairs together for light use is the stiffness added by the risers and stringers trying to bend in opposing directions like a torsion box. Nailing pattern better be tight, and hope you don't mind squeaks. It's rough that the biggest things you can get out of a big box store in my area are either a 11 1/4" 2x12 or a 11 7/8" LVL
Given is the measurement of a hand railing for staircase. This design is made up of 1 x 2 in. Tubular bar. If the standard length of a Tubular bar is 19 ft, how many tubular bars is needed if you will create this handrail for four (4) staircases?
How about $40 per board difference between a 2x10 and 2x12 16' long? Doing a long staircase myself consisting of 14 steps. Plan on doing 4 stringers for a 42" wide staircase.

When I made mine, I used 12" and works fine.
2”x12” is my preferred stringer choice

Just multiply the amount per step by the amount of steps.

That's nuts.
