Wire fence install

[nobody]

Looking to install some standard 2"x3" welded wire utility fence. A couple quick questions.

First how deep do I need to sink the posts? (Do I need 6' posts for 4' fence or 5' posts?) How far apart on the posts?

Any input and opnions would be great

Thanks

If you have sandy soil, then I suggest you sink 3 feet and cement the bottom.

If you are in bedrock, then 18 inches will me way more than enough and plan on half a day of chiseling per hole. Cement the post so it doesn't catch water.
