The following formula will help you compute the number of fence posts you need.
Fence posts not in straight line.
When you lay out the perimeter of a fence you can do it the traditional way using strings or if you re a techie using a laser.
Lack of light and a rush to finish the job before a thunder storm resulted in one fence post being slightly out of line about 1 1 5 inches.
If the posts somehow end up in a non plumb situation you maybe can drive large wedges from pt wood in the ground next to them.
I just finished installing wood fence posts for a 5 5 foot privacy fence.
What are my options to fix this.
Considering this your corner posts should be longer and if possible larger than your line posts.
Corner posts should be buried deeper to the ground at least 2 3 of the entire length of the post compared to your line posts at least 2 feet.
For the extra couple bucks for the longer post and the extra couple bucks for the setter its well worth it 10 years down the line when the fence is still strong as ox and straight as arrow.
