Slide 17
16. If a set of stairs does not have a landing, what should
its maximum rise be (Page 10.11, Section 5.1.1 Note)?
Answer
12’
Slide 18

Section 5.1.2)?
Answer
Measured from the face of one riser to the face
of the next riser (nosing not included)
Slide 19
18. How many risers and what will their individual height
be for a stair with a total rise of 8'-2“ (Page 10.13, Section
5.1.2)?
Answer
8’-2 = 98”
98”/ 7” (target riser height) = 14 risers
Divide the # of risers back into the riser height.
This is especially true if previous answer did not
come out even.
98” / 14 = 7” riser height
Slide 20
19. How many treads will a stair with a total rise of 8'-2"
and a total run of 9'-9",using the stairwell header used as
the last riser have (Page 10.13, Section 5.1.2)?
Answer
8’-2 = 98”
98”/ 7” (ideal riser height) = 14 risers
There will be one less tread than risers = 13
Slide 21
20. How wide would the treads be for stairs with a total
rise of 8'-2" and a total run of 9'-9" and using the stairwell
header as the last riser (Page 10.13, Section 5.1.2)?
Answer
8’-2 = 98”
98”/ 7” (ideal riser height) = 14 risers
There will be one less tread than risers = 13
9’-9” = 117”
117” / 13 = 9” for a tread width
Stairway requires 13 treads that are 9”wide.
