Public Spaces: Itineraries

Staircase Design for Accessibility

Staircases still play an essential role in urban design, but they must be built with accessibility in mind. Ensuring consistent step dimensions, clear markings, handrails, and tactile features will allow everyone, including those with visual impairments, to navigate vertical spaces safely and comfortably.

  • Stairs should have a straight direction with a minimum of 3 steps and a maximum of 12 steps per flight.
  • Ensure tread dimensions are at least 28 cm, and rise dimensions are consistent (between 13 cm and 17.5 cm per flight).
  • Mark steps with contrasting strips, ensuring visibility.
  • Include handrails on both sides and provide a clear space at the top and bottom of staircases with tactile guidance for visually impaired users.
  • Ensure a minimum height clearance of 2.20 meters.
