A properly sloped fence ensures aesthetic alignment, proper drainage, and stability on uneven terrain. This Fence Slope Calculator allows you to calculate the slope of your fence or the required height difference over its length.

Formula 1: Total Height Difference

The vertical change in fence height is:

$\text{Height Difference} = \text{Ending Height} - \text{Starting Height}$

Formula 2: Slope per Unit Length

Once you have the height difference, the slope per foot (or meter) is:

$\text{Slope per Unit Length} = \frac{\text{Height Difference}}{\text{Fence Length}}$

Example Calculation

Suppose:

Fence Length = 50 ft
Starting Height = 4 ft
Ending Height = 6 ft

Step 1: Total Height Difference

$\text{Height Difference} = 6 - 4 = 2 \; \text{ft}$

Step 2: Slope per Foot

$\text{Slope per Unit Length} = \frac{2}{50} = 0.04 \; \text{ft/ft} \; \text{or} \; 0.48 \; \text{in/ft}$

Final Answer:

Total Height Difference: 2 ft
Slope per Foot: 0.04 ft/ft (≈0.48 in/ft)
