Enter the horizontal distance and the vertical rise into the calculator to determine the slope of a fence. The slope is given as a percentage which can be used to build a fence on uneven ground.

Fence Slope Formula

The following formula is used to calculate the slope of a fence:

Slope () = (Vertical Rise / Horizontal Distance) * 100

Variables:

  • Vertical Rise is the vertical change in height over the distance of the fence (feet)
  • Horizontal Distance is the horizontal length over which the slope is measured (feet)
  • Slope is the steepness or incline of the fence expressed as a percentage (%)

To calculate the slope of a fence, divide the vertical rise by the horizontal distance and then multiply by 100 to get the percentage.

What is Fence Slope?

Fence slope refers to the steepness or incline of a fence relative to the horizontal ground. It is important for ensuring that a fence is built to accommodate variations in land elevation, which can be critical for both aesthetic and structural reasons. A properly calculated slope helps to ensure that fence panels are evenly spaced and that the fence line follows the contour of the land smoothly.

How to Calculate Fence Slope?

The following steps outline how to calculate the Fence Slope:


  1. First, measure the horizontal distance over which you want to build the fence (Horizontal Distance).
  2. Next, measure the vertical rise from the start to the end of the horizontal distance (Vertical Rise).
  3. Use the formula: Slope (%) = (Vertical Rise / Horizontal Distance) * 100.
  4. Finally, calculate the Fence Slope as a percentage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Horizontal Distance = 50 feet

Vertical Rise = 5 feet
