Ramps
- Gradient: 1:12 (ideal), 1:10 (maximum for short distances).
- Minimum width: 1200 mm.
- Handrails: 800–900 mm height, on both sides.
- Landings: Level landings at every 9 m or at change in direction.
Detailed Explanation
Ramps are critical elements in designing a barrier-free environment as they provide access for individuals with mobility challenges. The ideal gradient for ramps is 1:12, which means for every 12 units traveled horizontally, it rises 1 unit vertically. This slope is manageable for wheelchair users. A maximum gradient of 1:10 can be used for short distances, although steeper ramps can be more difficult to navigate. Ramps must have a minimum width of 1200 mm to ensure enough space for users. Handrails are essential for safety, placed between 800 and 900 mm high on both sides of the ramp for support. Additionally, leveling landings should be provided every 9 meters or whenever the direction changes, allowing users a safe resting place if needed.
Examples & Analogies
Think of a ramp as a gentle hill that everyone in your family can walk up together. If the hill is too steep, even strong family members might have difficulty climbing it, while younger or less able family members would struggle even more. By making the hill gently sloped (like the ideal ramp gradient), everyone can access what’s at the top without fear of falling or exhausting themselves.

- Audio-visual floor indicators.
- Braille-labelled control buttons at reachable height (900–1200 mm).
Detailed Explanation
Lifts and elevators play a vital role in providing vertical accessibility in multi-story buildings. The minimum size for a lift car should be 1100 mm wide by 1400 mm deep, which allows enough space for a wheelchair user to enter and maneuver comfortably. The doors must be a minimum of 900 mm wide to facilitate easy entry and exit. Inside the lift, audio-visual indicators announce the floor being approached, which helps individuals with visual or hearing impairments. Control buttons should be labeled in Braille and positioned between 900 mm and 1200 mm in height, so they are easily reachable for wheelchair users and individuals of different heights.
Examples & Analogies
Imagine stepping into an elevator with your friends while carrying a large box. If the elevator is too small, you all might squeeze in and face difficulties turning around or managing the box. Just like you would want the elevator to be spacious enough for everyone, including those who might need extra help or space, lifts designed according to these standards ensure that no one feels cramped and everyone gets where they need to go smoothly.

Additionally, symbols should adhere to ISO standards to ensure consistency and recognition across different environments. In transport and larger facilities, audio announcements can guide users, providing verbal cues about locations and directions.
Examples & Analogies
Consider walking through a large airport, where clear signage makes it easier to find gates, terminals, and services. Imagine if every sign was written in a way you couldn’t understand because of poor contrast or strange symbols! It wouldn’t just be confusing, it would be stressful. Signage that uses bold colors, textures, and sound works together, like having a good map combined with spoken directions, ensuring everyone knows where to go without frustration.
