Vinyl Fence Calculator

Measure the total length of the fence line in feet (add up every straight run). Enter that number, then pick your panel width — vinyl fence panels almost always come in 6 ft or 8 ft widths, and 8 ft is the most common. Choose your fence height and hit calculate. The calculator instantly tells you how many vinyl panels, posts, post caps and bags of concrete you need. Need to account for gates, meters instead of feet, or a price estimate? Open More options. Everything there is optional — leave it alone and you still get a complete materials list from the most common setup.

A vinyl (PVC) fence is built as a series of panels dropped between posts. To find the number of panels, you divide the total fence length by the panel width and round up, because you can't buy a partial panel. The number of posts is always one more than the number of panel sections — a straight run of 10 panels needs 11 posts, one at each joint plus one at each end. Every post gets a decorative post cap, so caps equal posts. Posts are set in concrete, and taller fences need bigger holes and more concrete per post. Each gate you add replaces a panel opening but still needs its own posts, so gates lower the panel count without lowering the post count.

Sections = ceil(Fence length ÷ Panel width)

Panels = Sections − Gates

Posts = Sections + 1

Post caps = Posts

Concrete bags = Posts × bags-per-post (1 bag for a 4 ft fence, 2 for 6 ft, 3 for 8 ft — 50 lb bags)

Quantities are always rounded up to whole units because you buy whole panels, posts and bags.

How many panels for a 80 ft vinyl fence? With 8 ft panels: 80 ÷ 8 = 10 sections → 10 panels, 11 posts, 11 caps, and 22 bags of concrete for a 6 ft fence.

How much vinyl fence for a 100 ft yard with a gate? 100 ÷ 8 = 12.5 → round up to 13 sections. Subtract 1 gate → 12 panels, plus 14 posts and 14 caps.

Using 6 ft panels for 60 ft: 60 ÷ 6 = 10 sections → 10 panels and 11 posts. Narrower panels mean more posts and more caps, so more hardware overall.

- Order one extra panel for a miscut or a damaged shipment — vinyl can crack in cold weather during installation.
- Corner and end posts often use a different routed profile than line posts; check with your supplier when the fence turns a corner.
- The concrete estimate assumes standard bagged mix and typical hole sizes. Rocky or sandy soil, or a windy exposed site, may call for deeper holes and more concrete.
- Gate openings usually want heavier posts set deeper — treat the gate posts as an upgrade, not a standard line post.
- Measure each straight run separately and add them up; measuring the diagonal across a yard overstates the fence line.
