Min stringer throat depth Check local building regulations for minimum stringer throat depth.
Enter Total Rise of stairs, from lower floor to top of upper floor, allowing for floor coverings etc. Select Ideal Rise from drop-down. The number of rises and actual rise is calculated to fit closest to selected ideal rise. After calculating and re-drawing stair plan diagram, a drop-down list of possible alternate rises is displayed. Select alternatives to re-calculate and display stair plan diagram.

If using notched stringers, mark out running measurements along stringer, then mark a framing square as shown (or use Stair Gauges) to mark notch cut-outs. Or cut a template at the size shown and use to mark out notches along the stringer.



Run options include:

Ideal Run - Use selected run to calculate total run.
Total Run - Calculate runs from total run entered.
Use Angle - Runs are calculated to suit entered stair angle.
Calculate Run - Runs are calculated by formula: Run = 630 - (rise * 2)

Add or subtract a single rise with the +Rise or -Rise buttons to re-calculate and re-draw stair diagram.

For concrete stairs, select Concrete Thickness and enter the throat thickness (see diagram) and Stair Width to calculate formwork dimensions and concrete volume. For wood stairs, select Stringer Width and enter the width of the stringer.

To calculate and display upper floor opening and stair headroom, enter upper floor thickness, check the Headroom check-box and select either the Headroom or Floor Opening radio button. Selecting 'Headroom' calculates upper floor opening from entered headroom. Selecting 'Floor Opening' calculates headroom from entered floor opening.
If your floor opening is unchangeable, select 'Floor Opening' and 'Use Total Run' to see if you can get an acceptable fit.

Uncheck Restrict to allow extreme stair dimensions. (eg: stairs on boats - pathway stairs on sloping ground etc)

Measure to Scale Check Scale Rule checkbox to display a ruler at the same scale as upper diagram. Print (100% printer scale), cut and use this scale rule to measure dimensions directly from diagram. (top diagram only)

Follow Local Building Regulations Be sure to follow local building regulations regarding all stair dimensions.
