Stairs

The Angle of the Stairs

What is the slope (angle) of the stairs, or what would the slope be if I used these measurements? The calculation is made from the rise of one step and the run of this step, assuming that all steps are identical. If you have the option to change your chairs, you can check what the result for the slope will be.

Note:
Do not include the thread nosing in the run measurement!
