ADA recommended slope for public access & walking elderly. Maximum ramp slope recommended for residential use with assistant. Maximum ramp slope recommended for loading unoccupied Determining the Correct Slope Ratio To determine the length of ramp for your application, you need to determine the rise. The rise is the vertical measurement between the ground and where the top of the ramp is going to be. Disability Systems recommends a 1:12 slope on most applications. Residential applications can use a 2:12 slope ratio if space is an issue but only if an assistant is present to help push the wheelchair or to help a person walking on the ramp. For commercial public access, a 1:12 ratio is required, check your local codes. 1:12 slope ratio (ADA Recommended) means that for every inch of rise, you will need one foot of ramp. As an example, a 12 inch rise would require a 12 foot ramp to achieve a 1:12 ratio. 2:12 slope ratio means that for every two inches of rise, you would need one foot of ramp.
As an example, take the total amount of rise in inches and divide by 2. If you have a 12 inch rise divide by 2 and the resulting number would be 6, this is the length of ramp which is required in feet to achieve a 2:12 ratio. 3:12 slope ratio means that for every three inches of rise you would need one foot of ramp. As an example, take the total amount of rise in inches and divide by 3. If you have a 12 inch rise divide by 3 and the resulting number would be 4, this is the length of ramp which is required in feet to achieve a 3:12 ratio. This slope ratio is only used to move an unoccupied wheelchair, never an occupied wheelchair and should never be used for walking. NOTE: For ADA compliance, any ramp that is used on a rise of 6 inches or more, must have handrails and be 36" wide. Any ADA compliant ramp longer that 30 feet (30 inch rise) must include a resting platform. Consideration must also be taken if the ground is not level and slopes away from the rise. Please be aware that ramps used by the elderly should be 1:12 and have handrails.

IR & Microwave Sensors Terms / Privacy PolicyChoosing the proper ramp length can seem like a daunting task - selecting a ramp that’s too short results in a steep grade, which is hazardous for a mobility aid user to safely navigate, especially in poor weather conditions. Choosing a longer ramp will decrease the steepness of the slope, making it safer and easier to use than shorter ramps, but a longer ramp requires additional space which may not be feasible in your location. The Discount Ramps team wants to ensure you have a strong understanding of the required calculations, we even have a handy mobility ramp calculator, making it quick and easy to choose which length is right for your home or office! Some powerchairs and mobility scooters may specify a maximum degree of incline which the scooter can safely climb. While this is not likely to be lower than what ADA specifications allow, it’s a good idea to check before you buy a wheelchair ramp.
Knowing the ADA Requirements will help you understand the figures that the Mobility Ramp Calculator outputs. For commercial use when somebody is sitting in the wheelchair or scooter while it climbs the ramp, ADA recommends a 1:12 slope, which means that every 1" of vertical rise requires at least 1’ (12") of ramp length (5 degrees of incline). Example: A 24" rise requires a minimum ramp length of 24’ (288") (24 divided by 1). The ADA requirements only apply to commercial buildings. The following general recommendations are often cited for residential construction. For residential use when nobody is sitting in the wheelchair or scooter while it climbs the ramp, a 3:12 slope is often recommended, which means that every 3" of vertical rise requires at least 1’ (12") of ramp length (14.5 degrees of incline). Example: A 24" rise requires a minimum ramp length of 8’ (96") (24 divided by 3). For residential use when somebody is sitting in the wheelchair or scooter while it climbs the ramp, a 2:12 slope is often recommended, which means that every 2" of vertical rise requires at least 1’ (12") of ramp (9.5 degrees of incline).
Example: A 24" rise requires a minimum ramp length of 12’ (144") (24 divided by 2). Typically available in lengths up to 2’, threshold ramps are perfect for maneuvering wheelchairs, powerchairs, and mobility scooters over short rises around the home or office, uneven surfaces, or through doorways where the bottom plate creates a challenging barrier. Portable wheelchair ramps are lightweight, compact, and many fold up for storage when not in use. These ramps are available in a wide range of commonly-used sizes, with lengths up to 12’. Modular handicap ramps are freestanding,configurable systems composed of ramp, landing, and sometimes stair sections, that can be customized to accommodate almost any home or business. Unlike other ramps, modular handicap ramps can include turns, that make it easy to assemble an access ramp in a confined space. Additional laws govern these permanent handicap ramps, which you can read about in our ADA Ramp Specifications article. Modular handicap ramps can be configured to accommodate any vertical rise height.
A wheelchair ramp in France A wheelchair ramp is an inclined plane installed in addition to or instead of stairs. Ramps permit wheelchair users, as well as people pushing strollers, carts, or other wheeled objects, to more easily access a building. A wheelchair ramp can be permanent, semi-permanent or portable. Permanent ramps are designed to be bolted or otherwise attached in place. Semi-permanent ramps rest on top of the ground or concrete pad and are commonly used for the short term. Permanent and semi-permanent ramps are usually of aluminum, concrete or wood. Portable ramps are usually aluminum and typically fold for ease of transport. Portable ramps are primarily intended for home and building use but can also be used with vans to load an unoccupied mobility device or to load an occupied mobility device when both the device and the passenger are easy to handle. Ramps must be carefully designed in order to be useful. Many jurisdictions[] have established minimum widths and maximum slopes.
A less steep rise can be easier for a wheelchair user to navigate, as well as safer in icy climates. Wheelchair ramps (or other ways for wheelchair users to access a building, such as a wheelchair lift) are required in new construction for public accommodations in the United States by the Americans with Disabilities Act. In the U.S.A, the Americans with Disabilities Act (ADA) requires a slope of no more than 1:12 for wheelchairs and scooters for business and public use, which works out to 1 foot of ramp for each inch of rise. For example, a 20-inch rise requires a minimum of 20 foot in length of ramp. Additionally, ADA limits the longest single span of ramp, prior to a rest or turn platform, to 30 feet. Ramps can be as long as needed, but no single run of ramp can exceed 30 feet. Residential Applications usually are not required to meet ADA standards (ADA is a commercial code). The UK's guidelines as recommended by the DDA are a maximum of 1:12 for ramps (with exceptions for existing buildings) "Ramps should be as shallow as possible.
The maximum permissible gradient is 1:12 [...], with the occasional exception in the case of short, steeper ramps when refitting existing buildings."[3] The UK's guidelines as recommended by the DDA are a maximum of 1:12 for ramps (with exceptions for existing buildings) "Ramps should be as shallow as possible. Ramps can have a maximum going of 10m, beyond which there has to be a landing before continuing as a ramp. The maximum permissible gradient for non domestic dwellings, 1:12, applies to ramps with a going no greater than 2m. This equates to a maximum Rise of 133mm. The gradient of the longest permissible ramp going of 10m must not be steeper than 1:20. This equates to a maximum Rise of 500mm. In between these two limits of ramp goings the allowable steepest gradient varies in a graduated way. This is shown in the Building Regulations 2004 Part M on a graph from which the reader is required to interpolate the allowable gradient. Alternatively, there is a simple calculation method which gives a very accurate result.
The formulae for these are : (1) TO CALCULATE THE GOING FOR A KNOWN RISE (all dimensions in mm.) Going = (Rise X 10 000) / (1000 - Rise) Note. The calculated Going is the minimum allowable for the given Rise. (2) TO CALCULATE THE RISE FROM A KNOWN GOING (all dimensions in mm) Rise = (Going x 1000) / (Going + 10 000) Note. The calculated Rise is the maximum allowable for the given Going. In Hong Kong, wheelchair ramp may not exceed a 1:12 slope for wheelchairs except in some situations under the Barrier Free Access (BFA) terms. In Australia, the Australian Standards Council requires a wheelchair ramp to have a maximum incline of 1 in 14. This means that for every 14 meters travelled horizontally, the ramp rises 1 meter. The wheelchair ramp must also have a minimum width of 1 m.[5] Wheelchair accessible vehicles may also include a ramp to facilitate entry and exit. These may be built-in or portable designs. Most major automotive companies offer rebates for portable ramps and mobility access equipment for new vehicles.
