Rise and going relationship formula
The relationship between step rise and going dimensions must satisfy the formula 2R + G, which should fall between 550 mm and 700 mm to ensure safe and comfortable stair proportions.
Subject to paragraph 3.12 the relationship between the dimensions of the rise and going is that twice the rise (R) plus the going (G) i.e. (2R + G) should be between 550 mm and 700 mm. The rise and the going are given in Table 3.1.
