Is 2 feet deep enough for fence posts?

A hole that is 2 feet deep may be enough for your fence posts, but the depth of a post hole depends on several factors. A depth of 2 feet may not be sufficient for the most common fence height of 6 feet tall if your soil is loose, you have high winds, or you have a frostline that's deeper than 24". If you aren't sure if a hole that is 2 feet deep is enough, ask professional installers in your area. They will have enough experience to know the optimal depth.  In general, a depth of at least 30" is common for a 6-foot tall privacy fence. A lower depth may be necessary if you have a frost line because the ground may heave when it freezes and thaws which will cause the posts to lean. If you are considering a Trex fence and want to make sure you get 30" in the ground for 6-foot tall fencing, be sure to order the 9-foot posts. If you do not need to go that deep, we sell 8' posts. And, if you need to go deeper, we also offer 12' posts. As a rule of thumb, we also recommend consulting our Installation Guides, as well as consulting with local installation experts.
