Tread and Riser Count
Number of treads and risers: You'll have one more riser than tread in a run of steps - the riser count above will fill automatically based on the tread count entered. For a split staircase, calculate/enter each tread count separately. Add the resulting footage together for the total footage you should order.
Tread + Riser Dimension
A typical dimension of a tread + riser is most often a total of 18 to 19 inches. This form uses 19 inches when calculating footage. If your stairs vary significantly from this dimension, you may need to adjust the footage required.
