How to Measure and Plan Fence Materials
Measure fence runs and gates, choose post spacing or panel width, and verify pickets, rails, concrete, fasteners, packages, waste, and cost.
How does this guide help you use the Fence Calculator?
This guide explains which values to enter, how the Fence Calculator processes them, and how to read the resulting estimate. Follow the sections below to check assumptions, compare realistic scenarios, avoid common input mistakes, and understand when an official source or qualified professional should take priority over a planning result.
Before You Start
Confirm that the proposed route is buildable before treating a tape measurement as a project length. Gather product specifications for posts, panels or pickets, rails, gates, concrete, fasteners, packaging, and current prices.
Map Every Fence Run
Measure along the proposed fence line and record each independent continuous run. Mark corners, changes in direction, slopes, gates, and places where the fence terminates against another structure.
The Separate runs field adds one starting post for each independent path. Corners, braces, elevation changes, and proprietary assemblies can require additional posts beyond this simplified model.
Separate Gate Openings
Enter the number of equal-size gates and one width per gate. The calculator removes their combined width from solid fence material while treating each gate as a span between posts.
Calculate unlike gate widths separately. Gate posts, bracing, hinges, latches, clearances, and support requirements depend on the selected assembly.
Choose Pickets and Rails or Panels
For a stick-built fence, enter maximum post spacing, rails per section, picket width, and picket gap. For a preassembled system, enter installed panel width. The calculator uses the selected value to round solid sections upward.
Verify Products, Concrete, and Packages
Enter actual pieces per package, bags of concrete per post, fasteners per material item, and fasteners per package. Product dimensions, package counts, footing requirements, and yields vary.
Extra material applies to pickets or panels before package rounding. Concrete and fastener quantities use their own entered rates and round upward separately.
How to Read the Results
Solid sections cover the fence length after gate openings. Total spans add gates. Posts add one starting post per separate run. In picket mode, rails apply only to solid sections; panel mode assumes rails are part of the panel system.
Base items reflect geometry. Order items include the entered extra percentage. Purchased items reflect whole packages, and spare items compare purchased quantity with the base count.
Entered Material and Labor Costs
The estimate separately multiplies posts, rails, purchased pickets or panels, concrete bags, gates, and fastener packages by their entered prices. Labor uses total measured fence length, including gate openings, multiplied by the entered linear-foot rate.
Delivery, taxes, permits, demolition, disposal, grading, staining, and other project charges are excluded unless incorporated into the entered rates.
Ordering Checklist
- Locate utilities and confirm boundaries and easements.
- Review permits, height, setback, pool, wind, and neighborhood rules.
- Verify actual post, panel, picket, gate, and hardware specifications.
- Size holes and concrete for soil, frost, exposure, and local requirements.
- Review slopes, corners, braces, gate posts, and end conditions.
- Round to supplier packages and confirm delivery, tax, and return policies.
Assumptions and Limitations
- Every gate uses the same entered width.
- Each gate is modeled as one span between posts.
- Solid sections use one spacing or panel width.
- Picket modules use one width and one gap.
- Extra material applies only to pickets or panels.
- Boundaries, utilities, structural design, slopes, codes, and installation details are not calculated.
