Do you guys use a formula for calculating stairs and landings for projects? I have a stair bid coming up and would like a little forsight on it. I am going to meet the customer tom and get grade points and measurements. Also to find out what exactly the customer would like....:confused:

i use math,works well for me ,divide by building code.

well... you gotta know that type of material your working with.... ex: versaloc block is a 6" step. it's just a matter of knowing what your working with. there really is no formula except knowledge.

I live in Baldwinsville...I work for somebody else...I am just an employee but he is starting to get me into doing more things then just install. So I am just a bit nervous on bidding on a job myself its the first one...:dizzy:

there is no way to give you an accurate answer.

So many different ways to build steps.

1) If they're open steps you need to account for the linear footage of tread PLUS the square footage of the side walls.

2) if they're closed steps you just need to account for linear footage of treads.

Ok, but even what I just typed is vague. Not done intentionally, just it's not that simple to give you a straight answer.

Building codes is something to be aware of. But the code will not state how to build. It will state *Maximum* tolerances. Such as max. rise. Min. tread width. Max differences in rise height. Etc. Stuff you need to know. Handrail requirements. yes, just about everywhere in america requires hand railing when so many risers exist. Again, stuff you need to know.

Rise & Run.... 7" rise by 11" is fairly comfortable for most people. Look at codes like everyone says. Look at the users. Are they elderly, do they have a lot of guests, entry way or casual garden path, etc? And CYA, have your boss help you with this so you can learn to build to his/her expectations and build an asset, not a liability.

Don't forget to consider wether you need to retain soil on one side, or both, of your stairs based on your design.
