Standard Ramps Vs. Curb Ramp: Understanding The Differences
When discussing ADA compliant ramp design, it’s important to distinguish between standard ramps and curb ramps.
While both fall under ADA ramp types and requirements, they serve different purposes and have distinct specifications.
Standard ramps are typically used for building entrances, elevated platforms, and other significant changes in elevation. Curb ramps, also known as curb cuts, are specifically designed to provide a smooth transition from a pedestrian walkway to a street level.
Standard Ramps | Curb Ramps |
---|---|
Longer runs with multiple sections and landings | Shorter and steeper than standard ramps |
User for heights differences of more than 6 inches | Minimum width of 36 inches, excluding flared sides |
Handrails on both sides | Do not require handrails due to their short length |
Maximum slope of 1:12 | Built with 1 1:10 slope for street-to-sidewalk |
Transitions | Require detectable warning surfaces (truncated domes) at the bottom |
Designing ADA Compliant Ramps
Designing ADA-compliant ramps requires careful attention to specific dimensions and proportions.
The design of ADA-compliant ramps involves a delicate balance between slope, length, width, and other factors that collectively contribute to their usability and safety.
Each dimension plays a crucial role in ensuring that individuals can navigate the ramp comfortably and independently. Let’s explore the specific requirements for standard ramp width, maximum rise, and length-to-rise ratio, which form the foundation of proper ramp design.

According to ADA guidelines, the minimum clear width of a ramp must be 36 inches. This width provides sufficient space for most wheelchairs and allows for easy maneuvering without the risk of wheels slipping off the edges.
- Maximum Ramp Rise: The vertical height the ramp can ascend before a landing is maximum 30 inches.
- Length-to-Rise Ratio: This ratio determines the slope of the ramp. The maximum slope allowed for a ramp is 1:12, which means for every inch of rise, there must be at least 12 inches of ramp length.
- Landing Requirements for ADA Ramps: Landings provide level resting areas and maneuvering spaces for wheelchair users and individuals with mobility aids. Ramp landings should be at least as wide as the ramp itself and a minimum of 60 inches long.
Slope Requirements For Wheelchair Access
The slope of a ramp is perhaps the most critical factor in ensuring its accessibility and safety for wheelchair users.
A properly designed slope allows individuals to ascend or descend the ramp with minimal effort and maximum control. It’s important to understand the nuances and best practices surrounding slope requirements. Factors that influence slope choice includes the length of the ramp, available space, and the weather conditions in the area.
- Steepest allowable slope: 1:12 (8.33% or 4.8 degrees)
- Recommended gentler slopes: 1:16 or 1:20
PRO TIP!
Always check for proper slope and width to ensure your ramps meet California’s ADA requirements for safety and accessibility.
