Side Slope Ratio Calculator

Enter run and rise to get instant ratios. Check percent slope, angle, and length quickly. Export results to share with crews and clients easily.

Calculator Inputs

Choose an input method, enter values, then press Calculate. All fields accept decimals.

Run is horizontal distance; rise is vertical change.
Ratios are unitless, but lengths follow your choice.
Controls rounding for percent, angle, and lengths.
For a 2:1 slope, H = 2.
Most specs use V = 1.
Angle is measured from horizontal.
Tip: Typical safe slopes depend on soil type, moisture, and loading.
