Stair counts are broken down into sections, those below and those above a landing. Working up from the riser just above the landing - Count the upper stairs only - please choose your tread/riser count (for this section only) from the drop down list above.
Tread = the horizontal component/the part you walk on. Riser = the vertical component between each tread. You will have one more riser than tread in each run of steps.
NOTE: If you have two landings within your staircase, this question is referring to the middle steps (this may just be a single riser between the 2 landings) - we'll ask for the uppermost steps/section later.
