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.
