  • RULES
  1. Width of the stair


The width of the stair is determined by the building use and the number of users

(60-50 cm per person)

We accept the following values:

-65cm to 120 cm for staircases in residential building

-120cm to 200 cm for staircases in public building


2. Headroom


minimum headroom= 190 cm

Normal headroom=220 cm

Exceptional headroom=185 cm(for cellar, attic….)


3. Dimension of the tread and riser


The ratio between the height and going(the step) is important: steeper a staircase is,the more tireing it is to climb it,but takes less room.

There are two considerations that must be thought carefully.

For a staircase to be comfortable, the going and the heights need to run on the foot step of an average person

(2 heights + 1 going=63 cm).cm


Maximum height:22 cm

ideal maximum height:18,5 cm (disabled or older persons)
