How deep do the posts go, and does that matter?

What fence installation companies need to publish

Post depth is the difference between a fence that stands for twenty years and one that leans in three, and it is invisible once the job is done.

How customers actually ask it

The same intent arrives in wording your page probably does not use. All of these mean the same thing:

  • “How deep do the posts go, and does that matter?”
  • “fence post depth”
  • “why did my fence lean”
  • “concrete footings for a fence”

What a complete answer contains

For fence installation companies specifically, an answer is only complete when it covers all 5:

  1. 1

    The general depth rule, expressed as a fraction of post height

  2. 2

    The frost line, and why depth below it is non-negotiable in cold climates

  3. 3

    Whether posts are set in concrete, gravel, or both, and the drainage argument between them

  4. 4

    That gate posts and corner posts are set deeper and larger than line posts

  5. 5

    The specific failure being prevented: frost heave and rot at the ground line

A worked example

Illustrative — not a real business

A third of the post's above-ground height is the general rule, so a six-foot fence gets posts about two feet down. In our climate the binding constraint is the frost line — footings must sit below it, or winter heave will lift and lean the fence no matter how well it was built. We set posts in concrete with a gravel base underneath so water drains away from the post end rather than sitting against it, which is what rots posts at the ground line. Gate and corner posts carry far more load and get set deeper in a wider footing.

What silence costs

A leaning fence at year three is unrepairable without redoing the posts, and post depth is the only thing that prevented it.
