Apl if you used an 8ft post with 6ft panels and had 1 3 in the ground then you would have about 5ft 4 above ground level if you then used a 4 gravel board then you would have the top of the panel flush with the top of the post a better rule of thumb i find is panel height plus gravel board plus 2ft min eg 6ft fence panels with 6 boards equals post 9ft 2700mm this would be 2ft6 in.
