Pitch of stairs - Rise and going
The rise and going dimensions for stairs are specified in Table 3.1, with flexibility allowed for exceptional circumstances where building constraints require different dimensions.
The rise and the going are given in Table 3.1. There should be not less than 2 rises and not more than 12 rises in each flight. There may be exceptional circumstances where a different rise or greater number of rises in a flight is more appropriate e.g. where there are dimensional constraints imposed by an existing building.
