form part of the
structure and guidance on the aspects of geometry and guarding
BS585 Part 1 1989: Woodstairs

and winder flights and quarter or half landings. Appendix A of this standard

BS6180 1982: Code of practice for protective barriers in and about buildings.
Private stairs intended to be used for only one dwelling with a
maximum rise of 220mm and a minimum going of
220mm. A maximum pitch of 42° is stipulated for domestic stairs.
Institutional and assembly

with a maximum
rise of 150mm and a minimum going of 280mm.
Other stairs covers
all other types of buildings, with a maximum rise of 190mm and a minimum
going of 250mm.
The normal relationship between
the dimensions of the rise and going can be expressed as detailed in Approved
Document K, which states that twice the rise plus the going (2R+G) should
be between 550mm and 700mm.
Pitch the angle between
the pitch line (notional line connecting nosings) and the horizontal.
The maximum pitch for
domestic stairs is 42°, semi-public stairs, eg factories, offices
