The result covers primary quantities, not every fitting. Brace bands, tension bands, bars, rail ends, caps, ties, wire, concrete, and gate hardware depend on the system and layout.

01 / Formula

How this is calculated

Rolls = ceiling((run − gate openings) × (1 + allowance %) ÷ roll length)

02 / Assumptions

What the estimate assumes

  • The entered roll length matches the supplier’s product.
  • Terminal-post count includes ends, corners, and gate posts.
  • Spacing is user-entered and must suit the actual fence and wind design.

03 / Worked example

See the math in context

A 150-ft run with one 4-ft gate leaves 146 ft of fabric. With 5% allowance and 50-ft rolls, the purchase estimate is 4 rolls.

04 / Guidance

Build a fitting schedule

Count terminal assemblies by type and line-post fittings by post count. Use the exact manufacturer or project detail for bands, bars, caps, rails, ties, tension wire, and hardware.

05 / Guidance

Check wind-sensitive designs

Privacy slats, screens, small mesh, tall fences, and exposed sites increase wind demand. Do not size posts or spacing from a generic residential takeoff.

Questions

Frequently asked

Do fence prices or dimensions have universal defaults?+

No. Product dimensions, labor, access, soil, wind exposure, finish, gates, permits, and local markets vary. Enter the measurements and current quotes for your project.

Does the result replace a site plan or product instructions?+

No. Treat it as a planning estimate. Confirm boundaries, utilities, easements, local rules, structural requirements, and the manufacturer’s instructions before work begins.

How should I handle corners and gates?+

Measure each straight run separately. Count end, corner, and gate posts as terminal posts, and subtract actual gate openings from fence fabric or panel length.
