I have a
question about my riser height.
-
I set my risers to a height of
7-1/2
to 8 inches like a straight stair, but I am short on treads. How come?
Remember, spirals are not straight stairs; they require higher riser heights to
work, typically in the range of
8-7/8
to
9-1/2
inches. Please check your paperwork or refer to the instructional video or manual
that came with your stair to determine the proper riser height for your stair.
- How do I calculate
my riser height?
The paperwork included with your order will have the riser height on it, but you
will want to double-check just to be safe. First, you remeasure your finished floor
to finished floor height. Then take that number and divide it by the number of risers
you have (treads plus your landing); the result is your riser height. For example,
if you have a finished floor to finished floor height of
108 inches
and have a 12-riser stair, your riser height would be
9 inches.
Please refer to the installation manual and video for more information.
- Do I have to
make an allowance for my riser height if I will be using wood tread coverings?
Yes, simply drop your landing the thickness of the wood covering from the upper
finished floor. Then use your normal riser height, which you figured by dividing
your finished floor to finished floor height by the total number of risers (treads
plus landing), for the entire installation. When you get to the bottom tread, you
will find that the distance from that tread to the floor below is short the same
thickness that you dropped your landing above to allow for the wood coverings. This
will allow you to add the wood coverings to all the treads and landing while keeping
the riser heights correct.
