Wheelchair ramps seem simple. After all, they’re just a sloped piece of metal, right? In reality, wheelchairs are a bit more complex. They require the right measurements in order to be safe and accessible for wheelchair users. Keep reading to learn what measurements are required to ensure that the ramp is both functional and safe for users.
Proper Incline Ratio
Perhaps the most important measurement for a wheelchair ramp is the incline ratio. The recommended ratio given in the ADA (Americans with Disabilities Act) is 1:12, meaning that there are 12 inches of ramp length for every 1 inch of height that it rises. For example, if your front porch is 3 feet high (or 36 inches), you would need a ramp that is 36 feet long in order to provide a safe and accessible slope for wheelchair users. Anything steeper than this may make it difficult for wheelchair users to roll up the slope, and may cause a loss of control when going down the ramp.
It’s worth noting that while the 1:12 ratio is ideal, homeowners are not technically required to adhere to this. Commercial properties, on the other hand, must strictly adhere to the measurements given in the ADA. So, if you need to have a slightly steeper ramp for access to your home, this is technically acceptable; just make sure that the slope is still navigable.
Ramp Width
The width of your wheelchair ramp is another crucial measurement to consider. A standard ramp should be at least 36 inches wide between the handrails to accommodate most wheelchairs. This width offers enough space for maneuvering and ensures the user can comfortably roll their chair up the ramp without hitting the sides. Just remember that this width should be the narrowest point of the ramp, meaning that you must measure between the handrails, not the sides of the ramp itself.
Handrail Placement
Speaking of handrails, there are a few important considerations for these as well. Handrails should be added to both sides of the ramp if there is a rise of more than 6 inches thepressedge, or a horizontal length of more than 72 inches. For safe use, the handrails should be installed between 34 and 38 inches above the ramp’s surface.
While these measurements are the ideal specifications for a safe, accessible wheelchair ramp, the best wheelchair ramps are those that are modified to meet your individual needs. Make sure that you speak with a professional wheelchair ramp installer; they will be able to get the right measurements for your property so that you can ensure your ramp meets your needs.
