What is Fence Post Depth?

Fence post depth refers to the portion of the fence post that is buried underground to ensure stability and support for the fence. The depth is typically a fraction of the height above ground to account for proper anchoring. This depth helps the fence resist wind and other forces that could cause it to lean or topple.

Example Calculations

Example 1: If the height above ground is 6 feet:

\[ FPH = 0.40 \times 6 = 2.4 \text{ ft} \]

The fence post depth needed is 2.4 feet.

Example 2: If the height above ground is 10 feet:

\[ FPH = 0.40 \times 10 = 4.0 \text{ ft} \]

The fence post depth needed is 4.0 feet.
