Hypothetical planning example

Straight 80-foot panel run

See how an 80 ft panel run produces full modules, a final bay, and boundary posts from the shared calculator.

Question this answers

If my backyard run is 80 feet with 8-foot panels, how many panels and posts does the calculator buy?

Assumptions

  • Single straight run, 80 ft centerline length
  • Panel fence system with panel-only module (8 ft panel + 4 in post face)
  • Default hole and concrete bag-yield settings
  • No gates on the run

Calculator result

Derived with the shared materials engine — not hard-coded in this page.

  • Total fence length: 80 ft
  • Fill length (excludes gate openings): 80 ft
  • Posts: 11 total (end 2, line 9, corner 0, gate 0, terminal 0, structure 0)
  • Concrete bags (project rounding): 68
  • 9 full panels, 10 panels to buy (cut bay 1: pitch remainder 5 ft, clear space 5 ft (valid))

What this result means

  • Panel purchases come from full modules plus any remainder bay that still needs a panel to buy.
  • Post count is driven by module spacing and ends — not by guessing one post every eight feet of tape measure alone.
  • Concrete bags follow freestanding posts and editable hole/yield assumptions — change those before treating the bag count as shopping truth.

What this scenario shows

  • Repeating panel pitch along one run
  • A final bay that is not a full module (cut panel purchase)
  • End posts plus line posts at module spacing, including the last full-module boundary

What this does not prove

  • This is a hypothetical planning example, not a surveyed property or completed install.
  • It does not model slope, frost depth, curves, or product-specific clearance beyond the calculator’s clear-space check.
  • Store SKUs and live inventory are outside the estimate.
