ᐅ Staircase – Are stair dimensions of 2.00 x 2.00 meters acceptable?

Hello everyone,

since I noticed the topic about stair dimensions in another thread and have been uncertain for a few weeks whether the stair measurements are acceptable, I’m bringing it here for discussion.

My only experience is with the stairs at my parents’ house, which are 2.30m x 1.65m (7 ft 7 in x 5 ft 5 in) and, in my opinion, comfortable to use.

Attached is the image with the measurements provided by the architect. The stairwell dimensions are exactly 2m x 2m (6 ft 7 in x 6 ft 7 in).

What do you think?

The applicable standard is DIN EN 18065, which defines the minimum requirements for a walkable staircase.

I design staircases using TrepCAD, where the relevant standards are integrated into the software. This ensures that, especially for spiral or curved stairs, the cutting dimension rules and optimal overlap of the treads are properly applied.

There are several different approaches to the overlapping of the treads.

The height of the handrail or balustrade often deviates from the standard and is set to a height of 1000 mm (39 inches).

The floor plan on the linked page 6 was version 0. The currently valid design can be found in the first post of that link.

Oops, yes, I just overlooked that. Yes, the one in the first post makes a great impression on me, and I’m not bothered by the stairs either. They are walkable—just a bit like what you’d find in a townhouse. But that was already noted there for other details of the design, which I still like overall. In that case, I’d rather see the home office become a bit "shorter" while the children’s rooms remain unchanged (?), if the stairs were slightly extended (which isn’t necessary).

Yes, we are no longer the pygmies on whom desk heights were once based. But not only are we getting taller, we are also living longer (and then grateful for less steep stairs).

The step size rule of 63cm or 65cm (25 inches or 26 inches) basically has nothing to do with the steepness of the staircase, but only with the ratio of riser height to tread depth. This rule deals with how much a step shortens when you step onto a higher point.

Oops, I missed that just now. Yes, the one in the first post gives me a very good impression, and the staircase didn’t bother me there. It’s usable—just a bit townhouse-like. But that was also noted for other design details, which I still like overall. There, I actually see the study being made a bit “shorter,” while the children’s rooms remain unchanged (?), if the staircase were slightly enlarged (which isn’t necessary).

You’re absolutely right. It’s actually the study that will become the child’s room.

I also understand now what you mean by the townhouse-style layout, after seeing the pictures from HansHaus and his separate corridor. It definitely gives a different impression, that’s true. But maybe mine will be more loft-like.

We still really like the floor plan, and next week the architect will bring the quote for the extended shell construction. Looking forward to that...

The walking stride rule with 63cm or 65cm is fundamentally not related to the steepness of the staircase but only to the ratio between riser height and tread depth.

That is basically correct, however, with a stride length of 63 cm (25 inches) instead of 64.3 cm (25.3 inches) here, the riser height of 18.35 cm (7.2 inches) would of course be less steep (and even more so with 16 risers x 17.81 cm / 27.38 cm (7 inches / 10.8 inches)). In the phase when a walker or rollator is used, this is especially appreciated...

Bright staircase seen from above with wooden steps, railing, windowsill with plant, and two bottles.


I’d like to revive my thread and ask whether it’s possible to build a staircase like this given the conditions mentioned in the first post. I’m not sure if I might hit my head when going down to the basement or if a width of 1 meter (3.3 feet) is sufficient. At least in the photo, it doesn’t look any wider, and we really like it!
