cutting stair stringers

Im trying to lay out some stair stringers and im pulling my hair out. The problem is that the stringers are right at the length where 20' will work, but i don't have room for waste


At first i was laying the stringers out so they would be flush with the existing 2x12 and then put plywood roofing an 3" of decking on, so its all flush on the first step. The problem is with cutting 3 1/2 off the top step, it barely leaves anything to attach to the 2 x 12. Now im thinking i should make the first step lower, so you step off the deck down onto the first step.
Can anyone help me lay this out?

The concrete pad is 170" to the edge of it, so i figure to the front of the step it should give be 185". It will be 129 1/4 to the top of the decking, although at the moment, just the roofing is on

I use 2x3 Clear Cedar for exterior grab rails with a ¾” round over on all edges. Mounted with aluminum brackets (I wish I could get them in SS) just like an interior railing.

I’ll actually rip the 2x3 to 2 ¼” wide because I think the 2 ½” wide is just a little much for a grab rail where 2 ¼” feels perfect to me.

Whatever you decide to go with, make sure it meets minimum code, just much safer and no liabilities.

The 2x3 ripped and routered corners does make a nice handrail. Make sure it is 1-1/2" x 1-7/8" when done to meet the max. perimeter size per Code. 2-1/4" = 6-7/8" 2' = 6-3/8" still larger than max. of 6-1/4". http://www.arcways.com/pdfs/IRC2006.pdf
