Accessible ramps must include landings at the top and bottom, and whenever a ramp changes direction. The minimum size of these landings is a key part of ensuring safe, maneuverable access for wheelchair users. This article explains the minimum landing dimensions, how they fit with other ADA ramp requirements, and practical considerations for design and compliance.
Key Landing Size Requirement
The minimum size for ADA ramp landings is 60 inches by 60 inches (1.5 meters by 1.5 meters). This square landing provides enough space for a wheelchair to align, turn, and move away from the ramp slope safely. The 60×60 landing applies at the top and bottom of straight ramps and at each change in direction. When a ramp has a landing, it must meet this minimum size to comply with the ADA standards.
When Landings Are Required
Landings are required in several situations to protect safety and accessibility. A landing is needed at the top and bottom of a ramp. If the ramp makes a 90-degree turn, a landing is required at the turning point. Additional landings are required at each significant change in direction or run when the total rise or length of the ramp meets certain thresholds. In all cases, the landing must be at least 60 inches by 60 inches to satisfy the minimum standard.
Width, Slope, and Clearances Related to Landings
While focusing on landing size, it’s essential to understand how other ADA ramp dimensions interact with landings. The clear width of a ramp should be at least 36 inches, with a maximum slope of 1:12 (approximately 8.3%). For turning or maneuvering within a landing, there should be at least 60 inches of clear space in the direction of travel and around the landing’s perimeter. Handrails, edge protections, and door clearances must also be considered to maintain usable space on the landing.
Landing Design Details and Best Practices
- Location: Place landings at the top and bottom of each ramp run and at every 90-degree turn or other direction change.
- Surface: Use non-slip finishes and ensure consistent surface texture to avoid tripping or sliding hazards.
- Edge Protection: Install curbs or barriers along the edges of landings to prevent wheels from slipping off.
- Door Proximity: Ensure door swing and hardware don’t encroach on the landing’s clear 60×60 zone. Maintain a minimum clearance for operation.
- Interior vs. Exterior: Exterior landings may require weather-resistant materials and drainage considerations in addition to the 60×60 size.
Practical Compliance Tips
To ensure compliance with the 60×60 landing minimum, professionals should verify measurements on site during design and installation. Use accurate measuring tools, plan for full 60×60 clear space free of protrusions, and document all changes. When space is tight, evaluate reconfiguring the ramp layout to preserve required landings without compromising overall accessibility. If local codes or accessibility guidelines add stricter requirements, those take precedence over general guidelines.
Common Scenarios and How the 60×60 Standard Applies
Scenario A: A straight ramp with two landings. Each landing must be at least 60×60 inches, with the ramp length and slope meeting ADA limits. Scenario B: A U-shaped ramp with two 90-degree turns. Each turning point must include a 60×60 landing to accommodate turning and clearance. Scenario C: A ramp adjacent to a doorway. Place the landing away from the door opening to maintain a clear path and meet the 60×60 requirement while allowing door operation.
Overall Accessibility Impact
The 60×60 minimum landing size is a core element of accessible design, influencing safety, maneuverability, and independent use. Adequate landings reduce the risk of misalignment with the ramp and provide reliable space for wheelchair users to pause, orient, and transition between surfaces. Alongside width and slope requirements, landing size helps ensure that ramps function effectively in both public and private spaces across the United States.
Tools and Resources for Verification
Builders and designers can use architectural drawings, accessible design checklists, and code references to confirm compliance. Key resources include ADA Standards for Accessible Design and related state or local accessibility codes, which may offer supplementary details or clarifications. Building inspections can verify landing dimensions, edge protections, and the presence of required landings at all relevant points.
Common Pitfalls to Avoid
- Underestimating the need for a 60×60 landing when a ramp changes direction.
- Placing furniture or fixtures on the landing that reduces usable space.
- Failing to install ankle- or foot-level edge protection on landings.
- Neglecting to keep clear 36-inch ramp width alongside the landing for safe passage.
