Some of my fence is "stallion" heighth at 6 foot. I used 10 footers for the corners and brace posts set to 4 feet and 9 footers set to 3 feet for my line posts. Been awhile so I don't recally why the 10 footers were about 5-6 or 6-7 inches and the 9 footers were like 8-9. About killed me to set them.
Anyway, unless you have extremly rocky soil, 30-36 inches is not enough depth IMHO. Forget the cheapie 4x4's at HD and Lowe's. You need to find a yard that still carries post rated for below ground use. I guess I am lucky. I have a treatment plant about an hour drive. Good posts ain't cheap and cheap posts ain't good.
