3. Stair terminology and geometry

Stair geometry can be described by the terms `risea,

`goinga and `pitcha, (see Fig. 1.) The rise, the vertical

distance between two consecutive treads or between

a tread and a landing, is easily determined from the

#oor-to-#oor height where the stair is to be situated.

Since it is good design to have equally sized steps the

#oor-to-#oor height should be an exact multiple of the

rise. For example with a #oor-to-#oor height of 2.6 m,

typical in British dwellings, the rise could be 260, 236,

216, 200, 186, 173, 162, 153 mm, etc. Approved Document

K (Department of the Environment and the Welsh Of-

"ce, 1992) and British Standards (British Standards Institute,

1984) give guidance on acceptable rise sizes so that

the climb is not too excessive or the steps so low that they

become a tripping hazard. For domestic properties, these

limits are 220 and 100 mm, respectively. The going, the

horizontal distance between two consecutive nosings, is

also controlled. Again for domestic properties this would

be between 220 and 350 mm. The nosing is de"ned as the

part of the tread that overlaps the tread below. The

combination of rise and going is also controlled by pitch,

the angle between a line joining consecutive nosings and

the horizontal (the tangent of the pitch is equal to the rise

divided by the going) and by the relationship &going plus

two times the rise' (G#2R). Again for domestic dwellings,

the pitch is limited to a maximum of 423 and

G#2R between 550 and 700 mm.
