Vinyl fencing is sold as preassembled panels that slot into routed posts, so the count is more straightforward than a board fence. Three numbers cover it: panels, posts and concrete.
Panels
A panel fills the gap between two posts, so the panel count equals the number of sections. Divide the run length by the panel width and round up. A 96 ft run of 8 ft panels is 12 sections, so 12 panels. Each gate takes the place of a panel, so subtract one panel for every gate you add.
Posts
Posts are one more than sections, 13 for that 12-section run. The panel width sets the spacing for you, because the posts are routed to accept panels of one size. Add a post on the latch side of each gate.
End and corner posts differ from line posts: a line post is routed on two sides, a corner post on two adjacent sides, an end post on one. Count how many of each your layout needs so you order the right routing.
Concrete
Vinyl posts are usually set in concrete like wood, in a hole about three times the post width and a third of the fence height deep. A standard post in a 10 to 12 in hole takes roughly two to three 80 lb bags. Multiply by the post count.
Some installers fill the hollow vinyl post with concrete for rigidity, especially on gate and end posts, check your manufacturer’s instructions, as that adds to the total.
Let the tool count
Enter your run length, panel width and height in the vinyl fence calculator and it returns the panels, posts and concrete, with gates already deducted. To plan a yard with corners and more than one run, draw it in the fence drawing tool instead.
