1. Click here for the StairChart, to find what stringer combinations
fit your finished floor to finished floor height. Click the PDF
stair design (complete right column on StairChart) to download the
combination drawings document.
2. Choose your combination of stringers depending
on where you want the landing positioned; your choice automatically
indicates the height at which the top of the landing will be framed.
The landing should be no less than 12 inches thick. Almost all combinations
are reversible. Please
see examples on drawings #1 to 4. (pop-up window)
3. Then go to stringers chart (to the right) to
make your selection.

Stairframe stringers come in pairs of 2 to 7 steps of
7 1/4”, 7 1/2” and 7 3/4” riser heights. The stringer
measurements indicated in the stringers chart always include 1
extra top riser height leading up to the landing or the top
floor.
Longer stringers of 8 steps and more are obtained by combining stringers
of the same riser height thanks to the easily bolted 11
gauge Stairframe Connectors, available separately. As the use
of a Connector eliminates the extra top riser height, all
measurements shown in the stringers chart apply without exception,
no matter how many Connectors are used in a stringer.
Ex.: A9 = A5 + A4 with Connector, B11 = B6 + B5 with Connector.
Single definitions indicate straight staircase designs (Ex.:
A14 = 15 rises @ 7 1/4 = 108 3/4). The same 108 3/4 height with a
landing can also be matched with 5 reversible combinations A2 A11,
A3A10,
A4A9,
A5A8,
A6A7;
here the landing can be framed anywhere from the 3rd to the12th step
level. |
