Chain-Link Fence Material Calculator

Estimate chain-link fabric rolls and post counts for one open straight run.

Inputs

Preset: 80 ft chain-link run

An 80 ft straight run with 50 ft rolls and assumed 8 ft post spacing, including two terminal posts. Corners and gates are not included.

Roll count - Length (ft), Roll length (ft)
Enter length in ft.
Enter roll length in ft.
Formula, inputs and conditions

Formula: ceil(Length/Roll length)

Decimal results are displayed to two places when needed.

Inputs
Net run length, fabric roll length and post spacing from the plan.
Outputs
Fence-roll, line-post, and terminal-post estimates for the stated straight-run layout.
Conditions and scope
Count one open straight run without gates or corners. Confirm fence height, foundations, loads, and hardware from the project plan or manufacturer instructions. Results are planning estimates, not engineering, permit, code or contractor-price decisions.

Separate fabric rolls from fence posts

Chain-link fabric and posts follow different counting rules. Fabric is sold by roll length. A straight run has two terminal ends, and the line posts occupy the intermediate positions. The simplified layout assumes no gates or direction changes.

Measure and calculate

  1. Enter the length of one straight open run.
  2. Choose roll mode for fabric or a post mode for the layout count.
  3. Replace the assumed post span with the spacing for the intended system.
Calculation method

Fabric rolls = ceiling(run length ÷ fabric roll length).

A worked example

Inputs
An 80 ft run uses 50 ft fabric rolls and assumed 8 ft post spans.
Calculation
Ceiling(80 ÷ 50) = 2 rolls. Ten spans give 11 total posts, of which 2 are terminal and 9 are line posts.
Result
2 roll

The initial result is 2 rolls. The post counts describe the simple run only; they do not include gates, braces or extra terminal points at changes in direction.

Output interpretation and next steps
Output or checkWhat it means for your project
Fabric rollsThe full run is divided by roll length and rounded up for purchase. Check how the product is joined and tensioned separately.
Line and terminal postsSeparate modes distinguish intermediate line posts from the two terminal posts of one open straight run. Gates and changes of direction need additional layout decisions.

Common questions

Are all posts line posts?

No. The endpoints of this model are terminal posts. Intermediate positions are counted separately as line posts.

Does roll rounding mean all leftover fabric is waste?

Not necessarily. The estimate counts rolls needed for this run and does not optimize reuse across other runs.
