What is unique to setting wood posts?
Post height, post spacing and hole diameter are unique to wood fencing.
Post heights for wood fencing will vary depending on the type of fence. However, regardless if the post is a line, end, corner or gate; all the posts are set at the same height.
Below are the various heights for the respective styles of wood fencing.

What is unique to the hole diameter?
Wood posts are generally 4” square. However, the cross section is almost 6” for a 4” square post. So, be careful to not undersize your hole diameter. Typically, a 10” diameter hole is required to set 4” square posts.
What is unique about posts spacing?
Almost all wood fences use 2” x 4” x 8’ rails to span between the posts. In consideration of grade changes and slopes, you will want to set your posts @ 7’ 10”. This will allow some room to assure that your rails will always span between the posts. Occasionally, you may have to use a 2” x 4” x 10’ rail because your post spacing varied to miss a utility line, etc. However, 2” x 4” x 10’ are generally more expensive and may not be available when you build your fence.
