Stairs

I have to build a set of stairs to go from my cottage's main floor to the new basement, can anyone tell me how to lay them out? I know you can use a framing square, or speed square, I just can't remember how to do it, any other input or ideas would be appreciated, Thanks!!

Divide the total height by 8. Round that number up, and divide it into the total height to give you the rise of each step. The run will vary based on home much room you have to work with. I would start with an even number like 10 and see how that goes. If that ends up too far, reduce accordingly.

So just set up your framing square to the rise and run and you are good to go. There are many other variables, but this will give you an idea.

do not use 8 as the denominator. its too high a rise. 7 or 7.5 are what gives a more comfortable stair to climb

Yes it matters.
There's a lot of codes that need to be followed when building a set of steps, and your going to need a permit and get it inspected.

I have always used 7 to start dividing, then use the whole number from that answer divided into the height again, to get the exact size of each riser. Also normally there is one less tread than riser, and the thickness of the tread should be cut off the bottom horizontal cut where the stringers set on the floor.

If you end up with say 14 risers you would normally have 13 treads. Starting like sixeightten says multiply tread size times number of treads and it gives you the total run. 9 in this case it would be 13 x 10 or 130 inches. then you know if it fits before you lay it out.
