I know that the general standard for post footers is to make the diameter of the footer hole 3 times wider than the post itself. However, I want to make sure that even in an 11' foot post (which seems kind of high to me), that this rule is still ok. Or should the footer hole be a bit wider for such a high post? The questions regards the corner post of an 11' foot high chainlink fence. Thanks in advance!

I have always gone down minimum 1/3 of what you have above ground. Diameter off twice the post the top 6" opening out to 4 times the diameter.if your post is not long enough to give you the minimum amount below ground weld or bolt something to extend it

    Hello, and welcome to Home Improvement. Your first sentence doesn't answer the original question; the second sentence is very confusing, and the third sentence seems dubious. Would you edit to clarify? Thanks.
