  6. ADA Ramp Specifications Require a 1:12 ramp slope ratio which equals 4.8 degrees slope or one foot of wheelchair ramp for each inch of rise. For instance, a 30 inch rise requires a 30 foot handicap wheelchair ramp. ADA Guidelines Require a Minimum 5' x 5' Flat, unobstructed area at the top and bottom of the ramp

1:20 is the minimum slope - below that value it's not considered a ramp (thus e.g., handrails are not needed) In each case, the maximum rise allowed is 30 inches (760 mm). These three ADA ramp slope values are preset in our ramp calculator The Wheelchair Ramp Calculator determines the ramp length, defined as the level horizontal distance from the wall of the building to end of the ramp, and the slope length, defined as the distance from the bottom of the door to the end of the ramp. The calculator bases the results on a slope of 1 vertical inch for each 12 horizontal inches We start you off with the ADA Standard Ratio of 1:12, but we recommend you refer to your equipment's user guide for exact recommendations concerning acceptable usage and allowable slope. Measure the distance from the top step/landing to the ground (Rise). Enter the values in the tool to determine the length of ramping needed ADA Ramp Specifications . As defined by the ADA, a ramp is a sloping route constructed with a slope greater than 1:20 (one inch of vertical rise for every 20 inches of horizontal length, or run) and must conform to the standard ADA specifications for ramps


Although other slope ratios may be used for constructing your ramp, the American With Disabilities Act (ADA) recommends a 1:12 slope. For example, if your porch height is 24 inches off the ground, you'll need a 24-foot ramp to safely accommodate wheelchair access The ADA requires that all business and public use wheelchair ramps adhere to a 1:12 slope ratio, meaning that for every inch of vertical rise there must be 12 horizontal inches (one foot) of ramp. If, for example, you had a stairway with a vertical rise of 21″, you would need 21′ of ramp A typical power wheelchair recommended incline capability is about 9.6° with the patient in the chair or scooter and about 14.5° unloaded. Pushing a manual wheelchair can be difficult or easy depending on: ramp length + patient weight. (all measurements in degrees) (all measurements in degrees

Example: A 24 rise requires a minimum ramp length of 8' (96) (24 divided by 3). Residential Occupied Use: 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) ADA Ramp Specifications Require a 1:12 ramp slope ratio which equals 4.8 degrees slope or one foot of wheelchair ramp for each inch of rise. For instance, a 30 inch rise requires a 30 foot handicap wheelchair ramp. ADA Guidelines Require a Minimum 5' x 5' Flat, unobstructed area at the top and bottom of the ramp. [ 1 The wheelchair ramp slope recommended varies depending on where you will be using the ramp, whether the chair will be occupied or unoccupied and of course any specific requirements you may have. Commercial or permanent access ramps require a slope of 1:12. Occupied residential, vehicle or portable access ramps require a slope of 2:12 A modular ramp provides the safest wheelchair and walker access for a 3-step rise. On the other hand, if you need a ramp for a set of three or more stairs, a modular ramp is the safest, longest-lasting solution. Modular ramps have several advantages in these situations

The CAE (Centre for Accessible Environments) say the maximum gradient for wheelchair ramps is 1:12, with the occasional exception in the case of short, steeper ramps when refitting existing buildings. The gradient also depends on the going of the flight with longer goings requiring shallower gradients For access to public places the maximum wheel chair ramp slope is 1:12. That means, for every foot of ramp height from the ground, you ramp must be at least 12 feel long. We normally use public access requirements when building for residential ramps as well; however, local building codes may be different First, wheelchair ramps must have a 1:12 ramp slope ratio for wheelchairs. This means that each foot of the ramp must have 4.8 degrees of slope for every inch it is rising. The slope of the ramp is important.

  3. A ramp is comprised of horizontal sloped runs connected by level landings between runs. Any slope greater than 1:20 and less than 1:12 along an accessible route shall be considered a ramp that is required to comply with ADA accessibility codes and compliances.
