Walk the proposed fence line and record every straight centreline segment separately. A segment begins and ends at endpoint-post centrelines. Mark corners and ends, then record each gate on its segment with both an offset and a clear opening width. This produces a checkable layout instead of one perimeter number that hides gate and corner conditions.
Still choosing a fence system? Compare wood, chain-link, and vinyl before collecting product-specific measurements.
This is the measurement record. After the layout is entered, use the chain-link material checklist to verify system-specific caps, bands, ties, braces, rail ends, and gate hardware before purchase.
Use the chain-link fence calculator after choosing the actual fence system, mesh-roll length, rail stock length, and a maximum line-post spacing appropriate to that system and site.
Walk and label the actual fence path
- Sketch property lines, fence lines, buildings, slopes, utilities, and planned access points.
- Label straight segments A, B, C, and so on.
- Measure each segment along the intended fence centreline using one unit system.
- Mark shared corners so adjoining segments reuse one physical endpoint.
- Record every gate's owning segment. Measure its offset along the segment line from the start endpoint-post centreline to the near inside face of the finished clear opening, then measure the clear width from that inside face to the far inside face.
- Record grade changes rather than averaging them into a flat line.
- Confirm fence height and the selected mesh, framework, gates, and bottom system.
- Copy package and stock lengths from the products that can actually be purchased.
Worked measurement record
Suppose the sketch has three connected segments:
- Segment A: 40 feet.
- Segment B: 60 feet.
- Segment C: 35 feet.
- Gate G1: 4 feet wide on segment A, starting 12 feet from A's start.
- Gate G2: 3 feet wide on segment C, starting 20 feet from C's start.
Total centreline length is 135 feet. The two gates total 7 feet, leaving 128 feet of base covered length before any user-selected waste. Keep both gates separate: each creates its own boundary conditions, and their widths must be deducted before mesh, top-rail, and enabled tension-wire stock are rounded.
Do not enter only 128 feet. That would lose the actual segment endpoints, both gate locations, and the geometry needed for post categories.
The calculator treats the two clear-opening boundaries as gate-post locations and does not subtract gate-post face widths from the segment length. Confirm the selected gate system's required rough opening, hinge/latch allowances, and post centres before field layout. Separate gates must have a positive fenced run between them; touching gates are rejected because this model assigns two distinct posts to every gate. If adjacent leaves are one manufactured assembly, enter its complete clear opening as one gate.
Keep the survey separate from the product record
On the survey, retain segment labels, endpoint connections, gate offsets and clear widths, grade changes and the locations needing system-specific pull or brace conditions. On the product record, keep height, mesh-roll length, top-rail stock length, optional wire-coil length and the selected maximum post spacing.
Check the selected gate's rough opening, hinge/latch allowances and post-centre dimensions against the field sketch. A nominal gate-leaf size alone does not establish the entered clear opening. Post sizing, footing selection and hardware counts need their own selected-system information.
The related chain-link material checklist separates calculator quantities from product-specific fittings. The measurement guide explains accepted input formats.
Limits and sources
The Chain Link Fence Manufacturers Institute product manual, revised March 2017, defines system terminology and shows that post selection and spacing depend on factors including fence configuration and wind context. It is not a residential site design for every project. Verify boundaries, utility-locate requirements, permits, wind exposure, frost conditions, and the selected manufacturer's instructions locally. MaterialNest's gate deductions and stock rounding are documented in the fence formula methodology.
