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))
| Item | Qty | Unit |
|---|---|---|
| 4x4 fence posts4x4 x 10 ft ground-contact | 11 | ea |
| Wood fence panels6 ft H × 8 ft W wood fence panel | 10 | ea |
| Cut panel (from stock panel)Final pitch 60 in O.C. · calculated clear panel space ≈ 56 in | 1 | ea |
| Concrete bags12 in × 36 in holes | 68 | bags |
| Pyramid post capsSized for 4x4 posts | 11 | ea |
| Panel mounting bracketsRail/panel brackets (system-matched) | 40 | ea |
| Bracket mounting screws2-1/2 to 3 in exterior screws · HDG or stainless | 150 | ea |
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.
