Calculating your gradient is straightforward once you know the Ramp Gradient formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Ramp Gradient Calculator.
What is Ramp Gradient?
The Ramp Gradient calculation tells you your gradient from a few simple inputs. The figure you are solving for here is the gradient, expressed in percent.
The Ramp Gradient formula
The core formula is:
Gradient = Rise (height) ÷ Run (horizontal length) × 100Here is what each input means:
- Rise (height) — a value measured in m. Example: 1 m.
- Run (horizontal length) — a value measured in m. Example: 12 m.
How to calculate it step by step
- Write down the rise (height) (for example, 1 m).
- Write down the run (horizontal length) (for example, 12 m).
- Apply the formula above to get your gradient.
- Double-check the result with the Ramp Gradient Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Rise (height) | 1 m |
| Run (horizontal length) | 12 m |
| Gradient | 8.33% |
| Ratio (1 in X) | 12.00 |
With rise (height) of 1 m and run (horizontal length) of 12 m, the gradient works out to 8.33%.
Example 2
With rise (height) of 2 m and run (horizontal length) of 12 m, the gradient works out to 16.67%.
| Result | Value |
|---|---|
| Gradient | 16.67% |
| Ratio (1 in X) | 6.00 |
Example 3
With rise (height) of 5 m and run (horizontal length) of 12 m, the gradient works out to 41.67%.
| Result | Value |
|---|---|
| Gradient | 41.67% |
| Ratio (1 in X) | 2.40 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
