The guys who laid stones for me earlier this spring also got the assignment to set the posts for my fence. They set posts with the dimensions of 500 mm height and 75 mm between the post irons. The posts are set with 1.5 m distance between each post.
The height of the fence will be 1.6 m high, the existing fence built by PEAB has beams with the dimensions 90X90.
The question is whether these posts are sufficient without resulting in a wobbly fence, as I live close to the coast on the Skåne plain, so it gets quite windy.
My options that I would like your input on:
# Go with these posts and buy beams with dimensions 70X70
# Go with these posts and buy beams with dimensions 90X90 but notch the lower part so they fit the post irons (looks nicer as the existing fence has beams of this dimension)
# Take up the posts and install new ones with wider distance between post irons (95) and then get beams with dimensions 90X90
Attached is a picture showing the posts and the existing fence (height 1.8 m and the section I will continue building on will taper down to 1.6 m height). The fence will be built in an L shape, with a total of 10 posts.

I would have gone with option #2 Use these plinths and buy rafters that are 900X900 but notch them at the bottom to fit the dimensions of the plinth irons (looks better as the existing fence has rafters of this dimension)
But the purpose is purely aesthetic.
But the purpose is purely aesthetic.
The vertical loads are relatively small in this context, so 70x70 will probably work just fine. However, when building fences, aesthetics are very important, so 90x90 is a much better option. The biggest concern from a construction point of view is lateral stability, which is not solved by the thickness of the posts. An angle in the street corner can help, but sometimes a supporting brace may be required.
When building with many horizontal slats, even small deviations become visible. It is best to choose extra high-quality wood for the slats and to join them securely. If all the slats are the same length and span from one post to the next, it can create a dull "hanging" character.
