Wooden fence post hole size.

Local building code will dictate post hole depth and diameter. The diameter of your post hole should be three times the diameter of your post. For a six foot tall post therefore you would dig a hole two feet deep. The ideal diameter meanwhile should measure three times the width of the post.

So for a standard 4 4 the ideal hole. Then calculate the volume for the part of the post that will be submerged in the hole. So if you re planning on using a four inch round or 4x4 inch square post your post hole will need to be 12 inches in diameter. Dig the first post hole.

Add to favorites reading time. 5 minutes fence post depth size and anchoring systems can make or break your fence line.

As stated above fence post holes should be 3 times the diameter of your post and 1 3 as deep as your post. Two 50 pound bags of fast setting concrete will set a 4 inch by 4 inch or a 4 inch diameter post in a 10 inch diameter hole 2 feet deep.

Your post diameter and height determine how big each hole needs to be. For a wooden fence you re going to need a few spare 2x4x8s to create some bracing for your fence panels. Cedar boards naturally resist decay and insects and they work whether you decide to stain the wood or leave unfinished. In order to straighten your post you re going to need to free it from the rest of the fence structure.

If your fence posts are 8 feet high then 2 1 2 feet of the posts should go from the bottom of the post hole to the plumb. Step 3 pour water into the dry mix and allow it to soak in. Dig the hole using the post hole diggers to about 2 feet 4 inches.
