Vinyl Privacy Fence Calculator (Tongue & Groove, No Gap)

Assumptions Used

Standard US residential vinyl/composite fence construction, one straight run, routed-post panel system with concrete-set posts. Post spacing matches the panel/rail's own manufactured length (6 or 8 ft) — vinyl panels lock into routed posts, so spacing isn't independently adjustable the way it is for wood. Privacy, Semi-Privacy, and Picket styles use the entered style's effective pitch (0" gap for privacy's tongue-and-groove, a small gap for semi-privacy, a real decorative gap for picket); Ranch Rail has no pickets at all. Rails-per-section is a direct product choice (2 standard, 3 reinforced/taller, 4 for Ranch Rail) — no reliable height-based formula exists for vinyl the way it does for wood. Post bury depth is a rule-of-thumb (buried = fence height ÷ 2) — always verify against your local frost line, which governs whenever it's deeper than this rule gives. Concrete volume uses each post's own square cross-section (posts are square like wood, not round like chain-link). Aluminum post insert reinforcement is mandatory (hinge-side) for every gate post regardless of the "reinforce all posts" toggle, since it's required for gate hardware strength, not optional. This calculator computes material quantities only— it does not verify structural post embedment for wind load, local fence-height ordinances/setbacks, or property line surveys. Scoped to routed-post concrete-set panel systems (standard for most vinyl and composite residential fencing) — some composite systems use a bolt-down aluminum post/rail system requiring no concrete at all; if your product uses that system, the post and footing quantities here won't apply.
