More or fewer steps
2.60 m (260 cm) can be climbed in fewer, higher steps or more, lower ones. Each opens in uCAD as this stair with that many risers.
| Risers | Each riser | Going | Pitch | Run of a straight flight | How it walks | In uCAD |
|---|---|---|---|---|---|---|
| 13 | 20 cm | 25 cm | 39° | 3.00 m | steeper, fewer steps | open |
| 14 | 18.6 cm | 26 cm | 36° | 3.38 m | steeper, fewer steps | open |
| 15 | 17.3 cm | 28 cm | 32° | 3.92 m | comfortable (drawn here) | open |
| 16 | 16.3 cm | 31 cm | 28° | 4.65 m | comfortable | open |
Limits differ by country: England’s Approved Document K allows a rise up to 220 mm and a pitch up to 42° in a home, Germany’s DIN 18065 up to 200 mm, and both ask for 2.0 m of headroom. Check the code that applies to yours.

Drawn as it’s built, in timber with open treads: treads housed in the stringers, posts under the turns, a railing on its newels. 330 parts in all, every bolt and weld among them. Sizes in millimetres, length × width × thickness.

Closed risers, a steel frame, another width or railing: change it in uCAD, and the parts are worked out again, with a cut list of the boards to buy. Sizes of the structure are the library’s defaults for a house stair, not an engineer’s calculation for yours.
Another height or width
Will it fit your room?
Open it in uCAD, draw your walls round it and look: turn it the other way, move the turn up or down, change the width. Or tell the AI: “a stair for 2.60 m in a 2 × 3 m stairwell”, and it draws one that fits.
