Designing a ramp can be a complex process, especially if you need to meet specific accessibility requirements. Our Ramp Calculator simplifies the design process by allowing you to calculate important measurements such as slope, angle, and length. Here’s how each of the calculator tools can help you design a ramp that meets your needs:

The Wheelchair Ramp Slope Calculator determines the slope required for your ramp to meet the maximum 1:12 ratio specified by the ADA. Simply enter the height of the ramp, and the calculator will provide you with the minimum length required to achieve the appropriate slope.

The ADA Ramp Slope Calculator takes into account additional requirements specified by the Americans with Disabilities Act. This calculator also provides minimum requirements for clear width and headroom. By using the ADA Ramp Slope Calculator, you can ensure your ramp meets all necessary guidelines.

Using our Ramp Calculator can save you time and effort in designing your ramp. Whether you’re building a ramp for a commercial or residential building, our calculator tools can ensure your ramp meets all necessary accessibility requirements

To calculate a ramp, you need to consider the rise (height) and run (length) of the ramp. The slope of the ramp is then calculated by dividing the rise by the run, and then multiplying the result by 100 to get a percentage. For example, if the rise is 12 inches and the run is 144 inches (12 feet), the slope would be 8.33% (12 ÷ 144 x 100).

A 1 in 12 gradient refers to a slope that rises 1 unit for every 12 units of horizontal distance. This equates to a slope angle of approximately 4.76 degrees. It is a common gradient used for wheelchair ramps and other accessibility ramps.

To calculate ramp gradient, you need to divide the rise (height) of the ramp by the run (length) of the ramp, and then multiply the result by 100 to get a percentage. For example, if the rise is 24 inches and the run is 288 inches (24 feet), the gradient would be 8.33% (24 ÷ 288 x 100).

The slope ratio for a ramp is the ratio of the rise (height) to the run (length) of the ramp, expressed as a fraction. For example, if the rise is 18 inches and the run is 216 inches (18 feet), the slope ratio would be 1:12 (18 ÷ 216). This means that for every 12 inches of horizontal distance, the ramp rises 1 inch.
