My house has 6 3/8 rise and 9 inch run. The treads are 10.5 inches.
this is a comfortable stair for me. Much less steep than the stairs I
grew up on. That house was built about 1900.

Take your tape measure and walk some new houses. I vaguely remember
7/11 as a ratio but that may have been commercial work.

My stairs are fine going up. Coming down they seem a little steep. I
have seen worse. Well both those areticle suggest rise+run=17-18" Mine
misses that by 1.5" which would explain why it feels a bit steep going
down. I have been in houses with about 8 by 8. Those really feel
steep.

Dan,

Here is my stair program in VB5. The second zip file down:

Play with different numbers and see what is legal or not.

Hi all,

A little background:

We're redoing the stairs in our 1865 house. They were
replaced in the 1920s or so and we're trying to put
them back more to their original configuration. There
are some walnut stair parts from the original stairs
in the attic and we plan on reusing as much of them as
possible.

We had an architect involved with some other aspects of
our renovation, and she also designed the new stair
layout for us.

The total rise between floors is 128". She designed a
staircase with 17 risers for a unit rise of 7.53". She
also specified a unit run of 11".

As I undersand it, this may or may not be code, but
definitely violates a couple of the guide formulas
that are commonly used (i.e. 2*rise + run = 24"-25").

I'm also reading that the rise should really be kept
at or below 7" and that you should only violate that
if you have space constraints or something.

So I was thinking of adding an extra stair (unit rise
would be 7.11") and making the unit run 10.5" (with +1"
bullnose). This would fall within the formula.

One other thing is that it's a straight stair. Is 18
steps too long to go up without a landing somewhere?

Does anyone have any experience with these issues that
might have some insight for us? We want the stairs not
to feel too steep. But we really want them to feel as
comfortable as possible.

Thank you very much in advance!
Dan
