Handrails are an important part of a safe, accessible wheelchair ramp. They give users extra stability while moving up or down a ramp and can make a difference for people who use wheelchairs, walkers, or other mobility aids. However, simply adding a handrail isn’t enough. Its height, clearance, gripping surface, and placement all impact how safely and comfortably it can be used, and there are specific requirements laid out by the Americans with Disabilities Act (ADA).
Williams Lift Company installs various types of wheelchair ramps, including residential and commercial wheelchair ramps, throughout New Jersey. With decades of experience helping people improve accessibility, our team can evaluate your space and recommend a ramp and handrail setup that meets your needs. Here, we discuss ADA handrail specifications you need to know.
Key Takeaways
- Handrails on ramps should be installed 34 to 38 inches above the ramp surface on both sides, measured to the top of the gripping surface.
- Handrails should provide at least 1 ½ inches of clearance from walls and other adjacent surfaces so users can grip them securely.
- Circular handrails should have an outside diameter between 1 ¼ and 2 inches. The gripping surface should also be continuous and free of sharp elements.
- Williams Lift Company can install ADA-compliant handrails and ramps throughout New Jersey.
What Are the ADA Handrail Specifications You Need to Know?
ADA handrail specifications make ramps easier and safer to navigate for everybody, whether you’re in a wheelchair or not. You must be able to reach the rail comfortably and keep a secure grip throughout the length of the ramp. Some specifications to know include:
Handrail Height and Clearance
Under ADA guidelines, the top of a handrail’s gripping surface should be 34 to 38 inches above the ramp surface. This range puts the rail at a comfortable height for people who use it for balance or additional support.
There also needs to be enough room for a person to wrap their hand around the rail. ADA standards call for at least 1 ½ inches of clearance between the handrail and a wall or other nearby surface.
Grip Size and Continuity
The size and shape of the handrail are also important because grip size affects its usability as much as the height. If the handrail is too large or too small, it may not provide the support you need.
For a circular handrail, ADA generally recommends an outside diameter of 1 ¼ to 2 inches. Non-circular handrails can also meet ADA guidelines, as long as their shape and dimensions provide a large enough gripping surface. If you’re unsure if your existing handrail complies, our technicians can help during our on-site assessment.
A usable handrail should also:
- Provide a continuous grip: The rail should run along the full length of the ramp, so users don’t have to repeatedly let go and reach for another section.
- Keep the gripping surfaces clear: Brackets and other components shouldn’t interfere with where a person naturally places their hand.
- Have a smooth, safe surface: Sharp edges and abrasive materials can make a handrail uncomfortable or unsafe to use.
- Offer reliable support: The rail and its mounting system should remain stable when someone uses it for balance.
Turns and Landings
Handrails also need to provide support as users enter and exit a ramp or turn on it. In most cases, ADA handrails should extend at least 12 inches beyond the top and bottom of a ramp run. At the top, the extension should continue horizontally. At the bottom, the extension continues in the direction of the ramp. These handrail extensions give users something to hold onto as they transition between the ramp and a level surface.
However, the setup is different for ramps with switchbacks or dogleg turns. At an inside turn, the handrail should remain continuous between ramp runs. This allows someone to navigate the turn without losing their support.
Handrail extensions should also end safely by returning to a wall, guard, landing surface, or another rail. These requirements are especially important for ramps with multiple runs or turns. When you reach out to us, we’ll make sure both your handrail and ramp meet ADA guidelines so users can travel smoothly from one end of the ramp to the other.
Residential vs. Commercial Handrail Requirements
ADA includes specific handrail requirements for ramps in commercial and public spaces, such as businesses, medical offices, stores, restaurants, and state and local government facilities. While these requirements don’t usually apply to homes, they can provide useful guidance when planning a safer ramp at home. Following similar principles for handrail height, grip, clearance, and continuity can make your home’s ramp safer and more comfortable for everyone.
Every home and user is different. When you’re planning a residential ramp, you should also consider:
- The user’s mobility needs: Someone who relies on a handrail for balance may need a different setup than a person who uses a wheelchair.
- The available space: Your home’s steps, porches, walkways, landscaping, and property dimensions can all affect the ramp layout.
- Ramp length and landings: Longer ramps, or ones that change direction, may need additional landings and handrails.
For homeowners, the goal is to create an accessible route for everyone. When you schedule an in-home assessment with Williams Lift Company, our team can help determine the right ramp layout and handrail configuration for your home and accessibility needs.

Frequently Asked Questions About ADA Handrail Specifications
What is the ADA-required height for a handrail?
ADA handrails should have a gripping surface that is 34 to 38 inches above the ramp surface. The measurement is taken vertically from the walking surface to the top of the gripping surface.
Are handrails required on both sides of a ramp?
Generally, yes. When a ramp has a rise greater than six inches, ADA standards require handrails on both sides. However, there are exceptions for certain ramp configurations. When you schedule an appointment with us, we take the entire layout into consideration when determining your ramp’s requirements.
How much clearance does an ADA handrail need?
There should be at least 1 ½ inches of clearance between the handrail and a wall or other adjacent surface. This space gives users enough room to comfortably wrap their hand around the rail without hitting the wall.
What size should an ADA handrail be?
For circular handrails, the ADA calls for an outside diameter between 1 ¼ and 2 inches. Non-circular handrails are also acceptable, though they are rarer. They also must meet specific requirements.
Do handrails have to extend beyond a ramp?
In most cases, handrails should extend at least 12 inches beyond the top and bottom of a ramp run. These extensions give users support as they transition onto or off the ramp.
Do residential wheelchair ramps have to meet ADA handrail requirements?
The ADA doesn’t apply to private residences in the same way it applies to public and commercial properties. However, ADA specifications can still be useful when designing a safe and accessible residential ramp.
