With a total rise of 104 inches, the speaker estimates 14 risers. Dividing 104 by 14 yields approximately 7.43 inches per riser (or 7 7/16 inches), which falls within his local code's acceptable range (5 3/4 to 8 inches). For a staircase, the number of treads is always one less than the number of risers, meaning there will be 13 treads. He notes that if the initial estimation of risers results in an individual riser height outside the acceptable range, the number of risers should be adjusted (e.g., adding or removing one) and the calculation repeated.

head room is going to be all right okay so I've already worked out the math so we had our total rise of 104 in so 104 divided by 14 I just took a rough guess I originally divided it by 133 but that gave me too big of a rise so then I went up one more Riser so 14 was my guess 104 divided by 14 risers gives me 7.43 in which is 7 and 7 16 well that falls in our in our comfort zone for what our Riser Heights can be and it's it's pretty comfortable step honestly so we're going to use 7 and 716 and 14 risers now I already said we're we always end up with one less tread than we do Riser so that means we're going to have 13 Treads the tread material I have is 11
