    I’ve erected an above fence screen using 75mm x 75mm posts which are 1.92m above ground with 50cm in postcrete. The panel is double slatted from wickes and has been cut in half to provide more privacy along the length of the fence. They are fixed to the faces of the posts. My wife now wants this all the way along the fence. However I’ve got concerns about the sturdiness of the posts. I realise for that height I maybe should have used 100mm x 100mm posts but I didn’t want it encroaching too much and did think it was a tad overkill. However the posts do have some flex at the top. They do return to their original position and the bases are solid.
    Is some degree of flex ok? Should i put some horizontal noggins between the 180cm span to help with rigidity? I may consider using 100mm x 75mm for further work.
    BTW it’s a long story as to why I’ve erected this after we did plan on replacing the fence in case anyone was wondering
    Thanks in advance

    You need a minimum of 600mm of post in the ground.

    Point taken thanks and I do plan on doing this moving forwards however for the existing 3 posts is a degree of flex at the top normal and would horizontal noggins provide any more stability?
