I have had a very successful 8 foot chicken wire fence for 10 years.
The pole tops are at 8 1/2 or 9 feet. The poles are 10 feet apart. Occasionally a really bad wind storm has made the poles lean outward, so I've added a couple more. They are the metal fence posts that go in with a pounder.
I run a neon green poly construction string around the very top, from pole to pole. That warns the birds that don't quite see it, but it also gets the fence up slightly higher without having extra fencing material. That string lasts at least 4 years where I am, and I can see it at a distance, so if any part of it breaks, I can spot it without having to walk the total circumference.
I ran one 4-foot chicken wire roll horizontally around the poles as the first bottom layer, bending it outward 6 inches at the bottom tight to the ground, so rabbits cannot get under it. I use galvanized wire to tie it to the poles.
Then the next horizontal level up is a 3 foot roll of chicken wire, which gets it up to 6-1/2 feet, and the string becomes the 8 or 9 foot level. If your top wall of your fence is uphill, make sure the string is extra high, as they will be able to stand higher and jump over more easily, so that's where the 9 foot string height helps. I ran a galvanized wire sort of "sewing" the edges where the two horizontal rolls meet, because the deer can learn to push through if they see an opening.
If you can spring for the fully galvanized wire, it will last for years and years. I had some construction chicken wire rust out, and the deer learned to push through the rusted parts. But it's not hard to replace it, if you need to start with the economy wire. I have found the construction wire, 200 foot roll for about $50.
