Build a Wheelchair Ramp Step 3: Now that you know the total run distance, or ramp length needed, select a ramp configuration that will work for your house. If the finished height of your porch is 24 inches from ground level, you’ll need 24 feet of ramp.

- Provide a landing at the top and the bottom of your ramp that is at least 60 inches long. This enables a wheelchair user to rest safely on a level surface. In addition, all landings where a ramp switches directions must have a level floor area of 60 inches in all directions.his is an issue if you need only a small ramp with a rise of less than 3 inches high. This provides stabilization in small rises. Build handrails on any ramp with a rise of more than 6 inches. Install handrails at height of 36 inches and make sure they are continuous on both sides of the ramp.

- Slope is given as a ratio of the height to the length. 1:12 means for every 12. inches along the base of the ramp, the height increases one inch. For a 1:12. maximum slope, at least one foot of ramp length is needed for each inch of. height.

- If the slope of a ramp is between 1:12 and 1:16, the maximum rise shall be 30 inches (760 mm) and the maximum horizontal run shall be 30 feet (9 m). If the slope of the ramp is between 1:16 and 1:20, the maximum rise shall be 30 inches (760 mm) and the maximum horizontal run shall be 40 feet (12 m).

- For example, if your porch is 18 inches above ground level, the ramp would have to be 18 feet long — and that does not include any landings! Try out ramps recently built in your community at the post-office, bank or municipal offices, for example, to see whether a 1 in 12 (1:12) ramp will work for you at home.

- 1 Calculated as 1 foot length of ramp for every 1 inch of total vertical rise (the rise divided by 1). 2  A 5 inch rise requires a 5 foot ramp, a 12 inch rise requires a 12 foot ramp and so on.

ADA Compliant Ramps: The Americans With Disabilities Act Sets Guidelines for Safe Ramps Key Clauses in the ADA Ramp guidelines. ADA ramps should not exceed a 1:12 ratio. Every inch of rise needs 12 inches of ramp. ADA ramps addressing more than 6 inches should have handrails. ADA ramps exceeding 30 feet must have an intermediate platform.

II. ARCHITECTURAL DESIGN CONSIDERATIONS 3). 3.3 Width Width varies according to use, configuration and slope. The minimum width should be 0.90 m. 3.4 Slope The maximum recommended slope of ramps is 1:20. Steeper slopes may be allowed in special cases depending on the length to be covered (fig. 4).

How to Build a Wheelchair Ramp 1 Ramps must have edge protection to keep anyone from slipping off. 2  Ramps must have landings at top and bottom that are as wide as the ramp and at least 60 inches long. 3  Handrails are required on both sides of all ramps that rise steeper than 6 inches or have a horizontal projection of more than 72 inches.o determine the slope of your ramp and how much horizontal space it will require, use the following calculation per the ADA guidelines: Multiply the inches your ramp will rise by the slope ratio you desire, and then divide the sum by 12 (to convert the horizontal space you'll need to feet).

- To find a 2:12 slope, find the rise in inches and divide by 2. The resulting number is the length of the ramp that is required in feet. Example: If the rise is 12 inches high, the ramp length needs to be 6 feet for a 2:12 slope.

- 1 You must provide a landing at the top and bottom of your ramp, at any place where the ramp turns and at the end of your maximum run. 2  The size of the landing will always be a minimum of 5 feet (1.5 m) square (60 by 60 inches). 3  Leveling. 4  An accessibility ramp's landings must be perfectly level. 5  Hand Rails.

- The slope is. extremely important because it affects how difficult it is to travel up and down the. ramp. If the slope is too steep, the ramp may be too difficult for someone to. use or may even be unsafe. Comparison of 1:12 and 1:20 slopes. A gentler slope has less resistance for either walking or wheeling. The 1 to 12 slope should be seen as the steepest slope to be built and may be too. steep for some people. Width: The width of the ramp should be at least 36 inches.

Wheelchair Ramp Slope Measure the distance from the ground to the top of the ramp. Then measure the length of the ramp. For example, if you find a ramp you like and it measures 3 feet to the top of the ramp and is 60 feet long, then the slope is 3:60 or 1:20.

A flat landing must be at the top and bottom of all ramps, and landings should always be at least as wide as the ramp itself and a minimum of 60 inches in length. Ramps that are used for direction changes should be a minimum of 60 inches by 60 inches.

ADA Compliance Ramps This means for every inch of rise the ramp needs to be 8” long; a 10’ rise means the ramp is 80” in length. This is the minimum allowed per the uniform building code and not the recommended slope. The recommended slope is a 1:12 ratio.

- The slope of the boat ramp should be steep enough to. launch the boat without the vehicle entering the water. Generally, ramp slopes from 15 percent (1.5 feet of drop. over a 10-foot length) to 12 percent ensure that boaters will. have little trouble launching or pulling their boats from the. water. If the slope is steeper than 15 percent, retrieving a. boat and trailer is difficult. A slope of less than 12 percent.
