A landing is a floor area provided at the top or bottom of a flight of stairs or a ramp, or a platform built as part of a stairway or ramp. Landings provide a safe surface for users to rest upon, allow design flexibility, and facilitate a change in direction.
Figure A-3.4.6.4. illustrates how to measure the length of a landing for various landing configurations turning less than 90 degrees, including straight landings.
Landing Configurations
Notes to Figure A-3.4.6.4.:
(1) L1 + L2 = length of the landing = the lesser of the required width of stair or ramp, or 1 100 mm See Sentences 3.4.6.4.(2) and 9.8.6.3.(2)
(2) D = distance from the narrow edge where the length of the landing is measured = half the required length of the landing See Sentences 3.4.6.4.(3) and 9.8.6.3.(3)
