: My garden fence has 4x4 posts on 7-8 foot centers, but I ran 1x4 rails : near the top and at the 30" line. I stapled 36" chicken wire to the : rail, and buried the bottom 6". So far so good.
I'm actually not a gardner, but I listen to this radio show "You Bet Your Garden",

. And I have a mind like fly-paper - all the stuff I don't want sticks.
Some of his answers are archived, and I found his fence advice at

. It says that no burrowing creature goes more than 1.5' down, so use six foot fencing with poles, with poles six feet apart. Use a trench digging tool to dig a two foot trench. Bury two feet of fence, stack three feet abovce ground, and leave the top foot loose and bend it outwards at 90 degrees. That prevents burrowing and climbing critters from getting past your fence. There's more advice at that URL.
Good luck!
