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.
You can see all possible options before choosing the most suitable for your stairs.
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 = 24~1/2" - (rise * 2)
You can add or subtract a single rise with the +Rise or -Rise buttons to instantly re-calculate and re-draw stair plan diagram.
For concrete stairs, select 'Concrete Thickness' and enter the throat thickness (as per 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.
If you select 'Headroom', the upper floor opening is calculated to suit entered headroom.
If you select 'Floor Opening', the headroom is calculated to suit entered floor opening.
Printing Tips: Uncheck 'Color' to re-draw stair and stringer diagrams without colour for printing. This saves inkjet or toner cartridges.
If you're having trouble printing with IE, try Firefox or Chrome. With Firefox, you can right click the image and select 'View Image' to open it in a new window and print or save the image only.
If the mages don't fit on the page, select 'Print Preview' and set page to 'Landscape'. Set scale to fit page before printing.
Uncheck 'Restrict' to allow extreme stair dimensions.
(eg: stairs on boats - pathway stairs on sloping ground etc)
