Calculation of 180 degrees turn wooden stairs with three flights and landing?
Simply enter the initial dimensions of your future staircase. You need to measure some dimenions , and some of them you can choose from optimum dimensional ranges for the convenience and safety of the stairs:
|The staircase angle||29 - 35 degrees|
|Riser height||15 - 17 cm / 7 3/4″ max|
|The tread depth||27 - 30 cm / min 10 inches, 254 mm|
|The tread thickness||4 - 5 cm|
|The riser thickness||2.5 - 3 cm|
|The stringer thickness||5 - 7 cm|
|Stairways width||94 - 110 cm / min 36 inches|
|The number of steps per flight||from 3 to 18|
|The width of the overhang of a tread (nosings)||3 cm/ between 19 mm and 32 mm|
|The height of handrails||90 cm|
|The headroom||not less than 203 cm / 6 feet 8 inches|
You need to measure the height and length of the future of the U-shaped staircase with three flights. Height is measured from the clean floor of the top floor ceiling of the lower floor, between which it is planned to build three-flight staircase.
Changing the source data - for example, the number of stages, you will be able to pick the perfect design stairs for your home.
I advise you to choose for each flight of stairs an odd number of steps to make the stairs easier to climb and descend.
