Enter the height above ground the fence will be (ft) into the Calculator. The calculator will evaluate the Fence Post Depth. 

Fence Post Depth Formula

The following two example problems outline the steps and information needed to calculate the Fence Post Height.

FPH = .40 * AGH

Variables:

  • FPH is the Fence Post Depth (ft)
  • AGH is the height above ground the fence will be (ft) 

To calculate Fence Post Depth, multiply the above ground height by .40.

How to Calculate Fence Post Depth?

The following steps outline how to calculate the Fence Post Depth.

  1. First, determine the height above ground the fence will be (ft). 
  2. Next, gather the formula from above = FPH = .40 * AGH.
  3. Finally, calculate the Fence Post Depth.
  4. 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.

height above ground the fence will be (ft) = 6

FPH = .40 * AGH = ?
