You need measurements of the distance between the floors to be able to calculate the space required for your stairs. This measurement is taken from finished floor to finished floor.
For a staircase to be comfortable to walk on, the step height (the distance between each step) should be between 170-200 mm and the step depth should not be less than 250 mm in the walking line. Now you can calculate how many steps your stairs will need, what is missing is the type of stairs, or the shape of the stairs. More detailed information about You can download the staircase's space requirements here but if we start from a staircase with 15 step heights that is 900 mm wide, the total outer dimensions will be as follows:
Straight stairs: 3600 mm
L-stair: 4500 mm
U-stair: 5400 mm
The different parts of the stairs are called runs. The total length of a staircase with two runs (L-stair) in this example is 4500 mm, the total length is distributed between the runs as desired.
There are many other things to think about when planning for a staircase, for example how the doors and windows around the stairs are located. Will the wall supervisor have to go over the window? Are you aware that the doorways are at such a distance from the stairs that the stairs will not protrude into the opening? Are there sloping ceilings on the upper level? Are there wooden studs in the wall that the stairs can be attached to? There are many questions and many measures to be checked. We have tried to compile the most important things to remember in the documents below so that you can avoid costly mistakes.

Spiral stairs
When it comes to spiral staircases, a few other "things to think about" apply.
The minimum recommended dimensions of a spiral staircase without vang is ø1900 mm (this requires a finished opening of 2000 mm). A spiral staircase measuring ø160 may sound like a good size, but keep in mind that it is only half of that measurement including the central pillar that makes up the width of the stairs, in other words, you have a staircase that is approx. 725 mm wide in the tread line. The norm for a normal staircase is 900 mm and it can feel cramped when you have to carry furniture up and down the stairs depending on the shape! We do not recommend spiral stairs as the only staircase in a villa where it is the only link between the floors. For a country house where you have access to both levels from ground level and don't have to carry large furniture between floors, the spiral stairs can be a real gem.
For a loft or as a supplementary staircase in a villa, a spiral staircase without vang (Svinga) can be made from ø1300-1900 mm (then the finished opening dimension will be 1400-2000mm, round or square).
If the dimension exceeds ø2000 mm, a wall piece is required for the load-bearing capacity. We then recommend that you look at ours model the Loop with bent-glued side flange.
