The Fuller Fence Materials List

This is the fuller, shopping-list version of a fence estimate — it starts from the same panel and post counts as the simpler Fence Calculator, then goes further to estimate the concrete needed to set posts, the number of rails if you're building a rail-and-picket style fence rather than pre-made panels, and a rough fastener count. If you only need panel and post counts, the simpler calculator is faster to use.

Panels = ⌈Perimeter ÷ Panel Width⌉  |  Concrete Bags = Total Posts × Bags per Post
Rails = Panels × Rails per Section  |  Fasteners = Panels × Fasteners per Panel

Example

A fully enclosed 100 ft × 60 ft yard has a 320 ft perimeter. With 8 ft panels, that's 40 panels and 40 posts (4 corner, 36 line posts). At 2 bags of concrete per post, that's 80 bags. If building rail-and-picket style with 3 rails per section, you'd need 120 rails, plus roughly 40 × 8 = 320 fasteners at 8 per panel connection.

Common Use Cases

  • Building a complete shopping list for a fencing project, not just panel and post counts.
  • Estimating concrete bags needed to set posts before a materials run.
  • Planning rail and fastener quantities for a rail-and-picket style fence build.
  • Budgeting the full materials cost of a fencing project, including hardware.

FAQs

How many bags of concrete does a fence post really need?

It depends on post size and hole depth, but 2 bags of ready-mix concrete per post is a commonly used rule of thumb for typical residential fence posts. Larger posts, deeper frost-line holes, or gate posts carrying extra weight often need more — adjust the field to match your post size and local frost depth requirements.

What's the difference between this and the simpler Fence Calculator?

The Fence Calculator gives you just panel and post counts. This calculator adds the rest of a real shopping list on top of that — concrete for setting posts, rails if you're not using pre-made panels, and a rough fastener count — so you can order everything in one pass.

Should I round the fastener and rail estimates up?

Yes — these are rough estimates based on your per-panel inputs. Buy a small surplus of rails and fasteners, since running short mid-installation usually costs more in a second trip than a modest overage would have.
