Dimension of posts?

[Anna1984]

I am planning to build a fence around the entire property. The property is about 50x50 m.

At the front, I'm thinking of building a traditional fence with posts and using regular decking wood, 28x120, as slats.

On the sides of the property and the backside, I plan to install wind/netting similar to this on posts:


The fence will be about 1 m high and I will use ground anchors for the posts, which I will drive into the ground.

My questions now are:
Should I use posts with dimensions 95x95 or 70x70?
How far apart should I place them?

I think 70x70 is both more attractive and strong enough.

Place the posts far enough apart so that the longitudinal beams extend past two "sections"; it becomes much sturdier, meaning with, for example, 5.4m longitudinally, the posts will be 2.7m apart.

Built one a few weeks ago, used 70x70 posts, ground anchors, and 28x120 decking. Then I did as larsbj wrote with the length in between. I think I went for 2.4 meters between and 4.8 meters decking length, and then not splicing on the same post

Don't you think the pickets will sag after a while if you have such a long distance between the posts? I probably wouldn't have more than 2 meters between them, if even that.

It entirely depends on the dimensions of the longitudinal rail.

The longest-lasting rule will also be 28x120, meaning the same timber and dimension as the slats. Can I have a greater distance between the posts if I use 95x95 instead of 70x70?

As I mentioned, I have about 2.5 meters between my posts, I wouldn't want more because it would become wobbly. Not because of the posts, but because of the decking timber. So if you want a larger gap, you need something thicker than 28.

Nicer with fine-sawn than decking for the fence, I think.

Looks nicer with fine-sawn than decking for the fence, I think.

Maybe, but it's really convenient to be able to build a fence from the waste of a wooden terrace. Then I plan to paint it white, so it will be less noticeable that it's treated.
