ᐅ Is a staircase required to comply with DIN 18065 or not?

I agree with @ypg, a tread depth of 23.26 cm instead of the 26.5 cm from my example, that’s more than a 3 cm difference.

And I thought the staircase length was limited to 250 cm. Here, 305 cm is planned.

The 250 cm limit cannot be met according to the standard. We acknowledged this and therefore extended the wall to 305 cm (120 inches).

We tested stairs with tread depths between 23 and 30 cm (9 and 12 inches). As long as the stairs do not have risers, this is completely fine for us (even at an older age).

Although I appreciate the reasonable ceiling thickness, there is certainly still potential for reduction in the clear height of 278cm (109.5 inches).

However, where stair use becomes painful even for young people due to injuries, this mainly concerns going downstairs.

And in my opinion, that is the wrong assumption—or a situation that can be compensated for with better planning.

It's like wearing shoes that are one size too small.

Could you please explain your statement in more detail?

We have planned a small house and would like to keep our room layout if possible.
You are all right that compliance with the DIN standards should be considered in many aspects. But isn’t it acceptable to find a good compromise in such cases?

We thought the same, but unfortunately, you have to subtract the 20cm (8 inches) ceiling joists again. That brings us down to 258cm (102 inches).

Everything has already been deducted for the clear height. If you enter incorrect values into the stair calculator, you will get nonsense results.

Which room layout do you want to "keep"? If the layout was based on incorrect assumptions, the calculation won’t work and the option to "keep" it is void.
As far as I remember, we still don’t know what the plan actually is here. Are you trying to downsize a catalog model?

As I said... other staircases are probably more comfortable to walk on.
But I prefer having 60–70cm (24–28 inches) more living space if it meets the DIN standards.

What good are the extra 60/70cm (24/28 inches) if you have to put a bed of about 2sqm (22 sqft), like your neighbors, on the ground floor or use the couch? A proper bathroom is probably not available on the ground floor either—you will have to rely on the upper floor in a small house.

Then show it. Maybe you can get advice on a good arrangement so that it doesn’t matter so much?! Many houses are designed with unnecessary clutter, awkward corners, and wasted space. Often, some adjustments are possible.

None of us can really know beforehand how difficult it often gets, even if we’re healthy. My husband now slowly shuffles up the stairs with stops due to health reasons; I myself value the stairs less after a foot surgery and several ligament strains. For the past year, a dog has been constantly underfoot... many neighbors now have hip or knee issues. The only advantage is probably that climbing up a steep staircase is easier.
