Stairs: every step the same
- How to check
- Measure the height (rise) of every step and the depth (going) of every tread. Write them down. Check the top and bottom steps too, after floor finishes.
- What good looks like
- Rise 150–220mm and going 220–300mm, pitch no steeper than 42°, and every step in a flight the same. Floor finishes may reduce the bottom rise by up to 12mm.
