Vinyl Fence Calculator

Separate routed line, end, corner and gate posts while estimating full and cut panels. Use the manufacturer’s installed module dimensions.

By Alish Gautam, Software Developer · Updated · Calculation methodology

Start with the editable example below. Dimensions retain their physical size when units change. Region sets currency labels without converting currencies; confirm entered quotes after changing region.

Fence layout

Run length includes gate openings. Gate offset is measured from the run start. Corner and straight connections share the preceding end post.

Whole packages round up. Allowance is separate from purchased surplus. Prices omit labor, delivery, tax and other items unless explicitly entered.

ASTM F964 concerns PVC profiles and material performance. It does not determine module width, foundation size or the selected manufacturer’s installation geometry.

How it works

Panel counts round each uninterrupted span. Physical graph nodes determine routed post type; one cap is counted per physical post.

Assumptions and limitations

ASTM F964 concerns PVC profiles and material performance. It does not determine module width, foundation size or the selected manufacturer’s installation geometry.

Whole packages round upward after the chosen allowance. Physical geometry and purchase reserve are separate. Manufacturer and project specifications override editable examples; the selected region does not establish a local code requirement.
