You can use soil and gravel instead of concrete when setting fence posts. However, concrete is more durable and longer lasting, so it's worth considering if you want your fence to withstand the test of time. You should especially consider concrete if you live in a region that experiences severe weather, which can damage your fence.

Your wooden gate post hole should be a third to a half of the height of the post. Also, note that the diameter of the post hole should be three times the diameter of the post. You should set the post in concrete to ensure a long-lasting and durable post that will withstand the test of time.

All fences offer some degree of privacy, but standard perimeter fences may not be designed with that in mind. Dedicated privacy fences, however, tend to enclose smaller areas and feature more high-end materials that truly emphasize seclusion and comfort. Additionally, privacy fences typically offer fewer gaps to peek in through than standard fences, though you can likely adjust that to suit your preferences. 

In the vast majority of cases, chain-link fences are less expensive than wood fences. Installing a wood fence costs anywhere from 20% to 30% more than a chain-link fence, or an average of $3,100, whereas a similarly sized chain-link fence will average around $2,400. Even with add-ons and additional protective finishes, a chain-link fence is very likely to cost you less than a wood fence. The only exception would be a split rail wood fence, which can cost about half the price of a chain-link fence or less.
