"Everyone deserves access." These powerful words from disability rights advocate Judith Heumann remind us why proper wheelchair ramps matter. Did you know that over 61 million Americans live with disabilities? Creating accessible spaces isn't just about following rules; it's about opening doors for everyone. Think of a wheelchair ramp as a welcome mat to your building. You want your welcome mat to be safe and inviting, right? Your ramp needs to be carefully planned just like that. About ADA Wheelchair Ramp Calculator Imagine having a personal accessibility architect. That's what this calculator is like! It removes the guesswork from ramp design by providing exact measurements that meet ADA standards. No more headaches wondering if your ramp is too steep or if you need extra landings! Total Rise/Height (inches): Desired Slope Ratio (1:x): Ramp Width (inches): How to Use the Calculator Enter Your Measurements: Type in the height (in inches) from ground to entrance. Choose your slope ratio (1:12 is standard, but 1:16 or 1:20 can be even better for easier access). Input your desired ramp width (must be at least 36 inches). Understanding Your Results: Required Ramp Length tells you how long to make your ramp. Slope Angle shows the steepness in degrees. Number of Required Landings indicates rest stops needed, making the ramp safer and more comfortable. Total System Length includes both ramps and landings. Handrail Length helps you plan your safety features. Reading the ADA Compliance Checklist Green Checkmarks Mean: Your design meets ADA standards. You're good to proceed with construction. People can safely use your ramp. Red X Marks Mean: Something needs adjustment. Review the specific requirement. Make changes before building. Real World Example Let's say your entrance is 30 inches high. Our calculator might show you need: A 360-inch ramp (using 1:12 ratio). One landing halfway up. A minimum width of 36 inches. Handrails extending 432 inches. Smart Planning Tips Consider extra width for people passing each other. Add non-slip surfaces for safety. Plan for proper drainage to prevent water accumulation. Think about cover from weather like rain or snow. Include good lighting to ensure visibility

You want your loading angle between 16–23 degrees. In most cases, setting the loading ramp at an 18-degree angle is perfect.How to Find the Right Loading Angle Every TimeIf your loading ramp is set at an incorrect angle, it can affect the stability and balance of the load being transported, as well as make it harder for you to get the job done. Therefore, it’s a good idea to know how to calculate your loading angTo find the right loading angle, you will need to know the length of the ramp and the height of the secondary surface (the surface the ramp is leading to), like the back of the truck you’re loading the machinery onto.If you’re keen to test your math skills, now’s the time to break out the pencil and paper, as well as a trusty calculator. In order to find the angle of your existing ramp, follow these steps: Begin by finding the ratio between the height of the secondary surface (the rise) and the length of the ground the ramp covers (the run), as opposed to the length of the ramp itself. This should be a 90-degree angle. To calculate the angle of your ramp as it stands, use the arctan (inverse tangent) function on your calculator with the following formula: slope (angle) = arctan (rise over run). Remember, as mentioned above, your desired angle for loading ramps is typically 18 degrees, with the safe loading angle range between 16 and 24 degrees. If your calculated angle is outside of this range, you may need to adjust the ramp’s length or the secondary surface’s height. Ensure this is done safely.When it comes to the simplest safe way to decrease the angle of a loading ramp, refer to your ramp’s manufacturer’s guidelines. You may need to detach the ramp from the secondary surface and shorten or lengthen the ramp as needed, then measure it again.Alternatively, if you don’t want the hassle of the trial-and-error approach, you can use the desired angle to calculate the required length of the ramp. The formula you need is: length of ramp = rise over sin (angle).For example, if the desired angle is 18 degrees and the height of the secondary surface is 1.5 meters, the length of the ramp needed would be 1.5 over sin(18), which equals 4.85 meters. Make sure your calculator is set correctly to ‘degrees mode’ when doing

Ramp in new buildings is 1:12. Maximum slope ratio in existing buildings: In existing buildings with space limitations preventing ratio compliance, a ramp with a total rise of 6 inches or less has a maximum slope ratio of 1:10. If the total rise doesn’t exceed 3 inches, the maximum slope ratio is 1:8. Cross slope ratio: A ramp’s cross slope — the slope running perpendicular to the direction of travel — has a maximum ratio of 1:50.A maximum slope ratio of 1:12 — 1 foot of ramp for every 12 inches of vertical rise — will let you align your residential ramp with ADA standards that enhance mobility device accessibility in your home.3. LandingsA landing is a flat area with plenty of space for mobility devices to turn at a change in ramp direction. ADA-compliant ramps have a landing at the top and bottom. They also have a minimum rise of 30 inches, meaning they include a landing for every 30 inches of height. A ramp also can’t run longer than 30 consecutive feet without a rest or turn platform. ADA-compliant landings have a minimum width matching the ramps leading to them and a minimum length of 60 inches. If the ramp changes direction at a landing, the landing needs a clear width and length of at least 60 inches by 60 inches.Some ramps with compound slopes don’t have level landings at directional changes. For example, curved and circular ramps continually change direction. These ramps don’t comply with ADA regulations

Having to rely on a friend, family member or caregiver. You can safely use the ramp on your own, letting you retain your independence and control.What Are the ADA’s Standards for Building Ramps?You can view the full commercial ramp codes on the ADA’s website. However, if you want to integrate ADA building guidelines into your home wheelchair ramp, here are the basic requirements to be aware of before starting your project. Let’s dive in!1. SurfacesADA-compliant ramps are durable and slip-resistant to ensure user safety: Durable: The ramp remains stable when you apply force and the surface resists denting and other forms of wear. Slip-resistant: The ramp offers ample friction so you can move safely across the surface.Any openings in a ramp’s surface are too small for a half-inch sphere to pass through. If the openings are elongated, the long dimension is perpendicular to the direction of user travel. An ADA-compliant residential ramp’s surface will be at least 36 inches wide. If you’re installing a bariatric ramp, you’ll want a surface width of at least 48 inches. You’ll want to keep these dimensions in mind when installing your handrails, as the clear width will fall between them.2. SlopesAn ADA-compliant ramp has several slope requirements:Minimum surface slope ratio: A ramp’s minimum surface ratio is 1:20 — in other words, it raises 1 inch for every 20 inches in length. Anything below this ratio is considered a standard walking surface. Maximum surface slope ratio in new buildings: The maximum slope for an ADA-compliant

(more on that at a latter date). For now we will err on the side of a circular radius for the tranny because they will be more likely to cause bucking than a clothoid, however we are using a “flat” takeoff. Centripetal acceleration on tranny: v0^2/r min= gy or r min= v0^2/yg (g = gravitational acceleration, y=allowable centripetal acceleration in units of g…gs (1.5 gs “best”, 3 gs max, but not recommended), r min, ft = v0^2(1609.3*5280)/(14.7*3600*3600) (this is the approximate transition radius minimum, but the next step (15) is a better approximation of what to shoot for.)Now that we know the flat takeoff length and the tranny radius (r min), we can estimate the length of the tranny if clothoid.Lc (length of clothoid segment, two segments total make the clothoid), Lc= A * sqrt of slope to lip angle, A= sqrt r min ^2 *slope to lip angle so Lc= sqrt r min ^2 *slope to lip angle * sqrt of slope to lip angle x2:~Total ramp length min (if clothoidal), ft = SQRT((RADIANS(r min^2)(lip degrees))SQRT(RADIANS(lip degrees)))*2This means the tranny length to the flat takeoff = ~Total ramp length – flat takeoff lengthSo at minimum give the transition to the flat take off this length, and make a smooth transition to the flat takeoff using your artist/sculptor eye.Back to the approximate HEIGHT: There are a myriad of possible heights, but:If the ramp is entirely circular all the way to the lip: This is not recommended as it can cause
