You asked, how do you draw a high spiral staircase?

Considering this, how do you calculate spiral staircase steps?

1. Floor height ‘h’ = 2700mm.
2. Riser ‘r’ = 225.
3. No of risers =2700/225 = 12.
4. No: of Steps = 11 + 1 landing platform.

Spiral staircases generally range in size from 42″ to 76″ in diameter. The floor opening at the top of the staircase must be two-square-inches bigger than the staircase‘s diameter. Spiral staircases are also measured by their floor to floor height, footprint, walking space, and landing length.

How are curved stairs calculated?

As with any stair, building curved stairs involves calculating the unit rise and run (height and length) of the treads and risers. Similar to straight flights, unit rise is calculated by dividing the total rise of the stair by the number or risers.

How tall can a spiral staircase be?

Most straight stairs have a typical riser height between 7” – 7.5” whereas spiral stair riser height has a maximum riser height of 9.5”. The reason for this is that as all the treads are set to a near 30 degree angle.

What are the dimensions of a staircase?

Standard Stair Dimensions Standard straight-run stairs have dimensions of a stair width of 36 inches or 91.4 centimeters, a stair tread depth of 11 inches or 28 centimeters, a stair riser size of 7 inches or 18 centimeters, and a length from the bottom to the top of the stairs of 10 feet or 3 meters.
