I am going to install split rail fence to mark the corners of my property. The corner posts are 5 feet 4 inches long. What is considered standard height of the rails and how deep should the corner posts be buried in the ground?
The standard that many people use for fence posts is that one-third goes in the ground. For your posts that would be 5.333 feet times .333 (1/3rd) equals about 1 foot 9 inches. If you are just going to put a couple of posts up to stack up the rails going in the 2 directions to mark the corners of your lot, your application will not be under much stress and you could get by easily just burying a foot and a half.
