- where a doorway opens onto a stair or ramp,
- where a ramp opens onto a stair, and

- Except as provided in Sentences (2) to (7), landings shall be at least as wide and as long as the width of the stair or ramp in which they occur.

- the required width of the stair or ramp, or
- 1 100 mm.
- The length of a landing shall be measured perpendicular to the nosings of adjacent steps or to the end of the ramp, at a distance equal to half the length required in Sentence (2) from the narrow edge of the landing.
- Where stair flights or ramps of different widths adjoin a single landing, the minimum width of the landing shall be
- where one or more of the stair or ramp widths do not exceed their respective required widths, not less than the greater required stair or ramp width, or
- where all of the widths of the stairs or ramps exceed their respective required widths, not less than the lesser actual stair or ramp width.
- Where a door swings toward a stair, the full arc of the swing shall be over the landing.
- The slope of landings shall not exceed 1 in 50.
- Where a doorway or stairway opens onto the side of a ramp, the landing shall extend for a distance of not less than 300 mm on either side of the doorway or stairway, except on a side abutting an end wall.
