Formula
The Ramp Gradient Calculator uses the formula:
Gradient = Rise (height) ÷ Run (horizontal length) × 100
Worked example
For example, with rise (height) of 1 m and run (horizontal length) of 12 m, the gradient is 8.33%.
| Rise (height) | 1 m |
|---|---|
| Run (horizontal length) | 12 m |
| Gradient | 8.33% |
|---|---|
| Ratio (1 in X) | 12.00 |

- Ratio
- A comparison of two quantities showing how many times one contains the other.
Frequently asked questions
Divide rise by run and multiply by 100. A 1 m rise over 12 m run is about 8.33%, or a 1-in-12 ratio.
Many guidelines recommend no steeper than 1 in 12 (about 8.3%) for accessibility.
It means 1 unit of rise for every X units of run, so a larger X is a gentler slope.
Increase the run for the same rise, which lowers the percentage and raises the ratio.
The Ramp Gradient Calculator uses the formula: Gradient = Rise (height) ÷ Run (horizontal length) × 100. For example, with rise (height) of 1 m and run (horizontal length) of 12 m, the gradient is 8.33%.
