Cross slope refers to the gradient of a surface across its width, indicating how steep the surface is relative to a horizontal plane. This measurement is particularly critical in projects requiring precise gradients for water drainage, road safety, and accessibility. The Cross Slope Calculator simplifies these calculations, ensuring accuracy and efficiency.
Formula of Cross Slope Calculator
The formula for calculating cross slope is relatively straightforward:
Here’s how you can apply it:
- Measure the vertical rise — the change in elevation between two points.
- Measure the horizontal run — the distance between these points.
- Divide the vertical rise by the horizontal run.
- Multiply the result by 100 to get the percentage of the cross slope.
Table for General Terms and Conversions
| Vertical Rise (in feet) | Horizontal Run (in feet) | Cross Slope (%) |
|---|---|---|
| 1 | 10 | 10.00 |
| 1 | 12 | 8.33 |
| 1 | 15 | 6.67 |
| 1 | 20 | 5.00 |
| 1 | 25 | 4.00 |
| 1 | 30 | 3.33 |
| 0.5 | 10 | 5.00 |
| 0.5 | 12 | 4.17 |
| 0.5 | 15 | 3.33 |
| 0.5 | 20 | 2.50 |

Example of Cross Slope Calculator
Consider you need to calculate the cross slope of a new wheelchair ramp. With a vertical rise of 1 foot and a horizontal run of 12 feet, using our formula:
Cross Slope = (1 / 12) * 100 = 8.33%
This value ensures compliance with accessibility standards, which typically require a slope of less than 8.33%.
