The basic answer is that a comfortable stair has about 7" risers and 11" treads. There are other methods, such as 2 risers + 1 tread %". In your case divide 108" by 7" to find the number of risers. Code restricts height of risers, I believe it is currently 7 3/8" if your risers get larger than this, you need to add another step. Find the total number of treads and multiply by 11"

Shouldn't this be find the total number of

Nah.

No, that's not. Dan said (generally) risers are 7" and treads are 11". He gave the math to calc the number of risers (108"/7"), but not how many treads would be needed according to that calc that in the end gives you the total length of the staircase. He simply said "find the number of treads and multiply by 11." Under that instruction, he didn;t give any calc on

even with floor . You find the number of treads exactly like he said,
depending how you want the first tread to fall. Then you multiply exactly
how he said. You multiply the run (tread width) by rise, exactly what he
said in answer to the OP's question of " I need to to see how long to make a

Make that you need yet another cup of java.

You said it in your post here, but Dan didn't make this clear in his original post, IMO.

I assumed . . . . . . .

A prudent person would make a sketch of the situation. I gave the correct method of determining the number of risers required.

Make a line on a piece of paper to indicate the floor at the bottom of the stair. Make another line to indicate the floor at the top of the stair. Make the sketch with the number of risers that were calculated. The number of treads does not necessarily equal the number of risers. It will be totally dependent on how you tie in the top and/or bottom.

From the sketch determine the number of treads that you will need to complete the stair as sketched. Multiply by 11" or whatever tread dimension you chose to use. If you are cutting the stringers you will need to do a lot more figuring. You will need to know tread depth, finish floor treatment at top and bottom. As an example, if you are looking at subloor dimensions before completing hard wood flooring, you will need to adequately consider this information in your calculations. Code will also require that you create an "even gaited stair" We have all stumbled on stairs with an odd ball riser at top or bottom.

Hope this made it more clear. I repeat, pictures are worth 100 words. Go to the library.

Another minor correction:
After you figure the number of treads and determine the tread width, say 11
1/4", than multiply the number of treads by 10, not 11 1/4. This would be
the run since there is a 1 1/4 overhang.

Just a minor correction (I hope). It has been years since I did it but doesn't the number of treads come to 1 less than the number of risers? Not sure now, and too lazy to look it up.

As state below, dived the height (rise) by 7 this will give you the number
of risers. (don't use 108, this is to the bottom of the ceiling you need to
the top of the 2nd floor).
Depending on how you build the stairs you will have either the same number
of treads (runs) or one less.

Fine Home Building has had a couple of very good articles on stair
design in the past 10 years. You might try to search their web site.
