🕒 Last updated: September 6, 2026
Inputs
ℹ️Total linear run — confirm against an actual property survey, not just a fence-line guess.
ℹ️Fabric only comes in fixed roll heights — check local ordinance limits, which are often lower at front yards than back/side yards.
ℹ️10 ft is standard residential spacing; tighten to 8 ft for taller fences or high-wind areas.
ℹ️The lighter intermediate posts along the run — 1-5/8" for fences up to 5 ft, 2" for 6 ft and taller.
ℹ️The heavier posts at the run's ends, corners, and gates — always larger than line posts since they alone carry the fabric's full tension.
Waste
ℹ️Applied to fabric, top rail, tension wire, and tie wires — 10% is a common estimating default. Not applied to the fixed post or concrete bag counts.

Tie wires (+10% waste): 165
Assumptions Used
Standard US residential chain-link fence construction, one straight run. Post count follows the same "one per spacing, minimum 2" on-center formula used elsewhere on this site — 10 ft O.C. is standard, 8 ft for taller fences or high-wind areas. Terminal posts (the run's 2 ends, plus 2 per gate) are always larger-diameter than line posts, since they alone carry the fabric's full tension. Post bury depth is a rule-of-thumb (buried = fence height ÷ 2) — always verify against your local frost line, which governs whenever it's deeper than this rule gives. Concrete volume uses each post's own round cross-section (unlike a wood fence's square post), subtracted from a footing hole roughly 3× the post's own diameter. Fabric is sold in full 50 ft rolls only; top rail and tie wire scale with the fabric run length, and waste applies to fabric, rail, tension wire, and ties — not to the fixed post or concrete bag counts. This calculator computes material quantities only — it does not verify structural post embedment for wind load, local fence-height ordinances/setbacks, or property line surveys.

Taller chain-link fence material takeoff
Taller fences and higher-wind-exposure sites commonly use tighter 8 ft post spacing and 2" line posts for extra rigidity, rather than the standard residential 10 ft spacing.
This page defaults to a 300 ft run at 8 ft height, 8 ft O.C. spacing — edit the inputs above to match your actual fence.
Chain-Link Fence Calculator Formula: How Is It Determined?
Post, fabric, rail, and wire quantities, plus footing volume, calculated separately and combined into a material takeoff.
Step 1 — Posts & Footings
Total Posts = max(2, ceil(Fence Length / Post Spacing) + 1) + 2 per gate
Terminal Posts = 2 (run ends) + 2 per gate; Line Posts = Total Posts - Terminal Posts
Buried Depth = Fence Height / 2 (derived from "bury 1/3 of total post length")
Concrete per Post = Hole Volume - Post's Own ROUND Cross-Section Volume
Post count follows the same "one per spacing, minimum 2" formula used for wood fence posts elsewhere on this site — only the split into line vs. terminal posts, and the round (not square) cross-section for concrete, are chain-link-specific. Buried depth is the same rule of thumb used for wood fence posts — your LOCAL FROST LINE always governs when it's deeper.
Step 2 — Fabric (Mesh)
Fabric Run Length = Fence Length - Total Gate Width
Fabric Rolls = ceil((Fabric Run Length x (1 + Waste %)) / 50 ft per roll)
Fabric is sold in full 50 ft rolls only — a partial roll can't be ordered, so the run length (with waste applied) is always rounded UP to the next whole roll.
Step 3 — Top Rail, Tension Wire & Ties
Top Rail Sections = ceil((Fabric Run Length x (1 + Waste %)) / Rail Length) + Gates
Tension Wire Length = Fabric Run Length x (1 + Waste %)
Tie Wires = ceil((Fabric Run Length x (1 + Waste %) x 12) / 24)
Top rail and bottom tension wire are each independently optional (toggle either on or off to match your actual installation plan). Tie wires follow the widely-used "every 24 inches" spacing rule for fastening fabric to rail and posts.
Worked Example
This example walks through your current inputs above, using the same steps as the Formula section.
Input Values Used
| Input | Value | Why it is used |
|---|---|---|
| Length / height | 300 ft / 8 ft | Sets post/fabric/rail counts |
| Line spacing / post sizes | 8 ft / 2" line, 2.5" terminal | Sets post count, split, and footing size |
| Top rail / tension wire | 10 ft sections / included | Sets rail section and wire length |
Step 1 — Posts & Footings
| Calculation | Result |
|---|---|
| Sections = ceil(Fence Length / Post Spacing) = ceil(300 / 8) | 38 |
| Total posts = Sections + 1 = 38 + 1 | 39 |
| Terminal posts = 2; Line posts = Total - Terminal = 39 - 2 | 2 terminal / 37 line |
| Buried depth = Fence Height / 2 = 8 / 2; Post length = Height + Buried = 8 + 4.0 | 4.0 ft / 12.0 ft |
| Total concrete = (Line Concrete x Line Posts) + (Terminal Concrete x Terminal Posts) = 28.01 cu ft, packed in 80 lb bags | 47 |
Step 2 & 3 — Fabric, Rail & Wire
| Calculation | Result |
|---|---|
| Fabric run length = Fence Length = 300, +10% waste | 330 ft |
| Fabric rolls = ceil(Run Length / 50 ft) = ceil(330 / 50) | 7 |
| Top rail sections = ceil(Run Length / Rail Length) = ceil(330 / 10) | 33 |
| Tension wire = Run Length (with waste) | 330 ft |
| Tie wires = ceil(Run Length (in) / 24) = ceil(3960 / 24) | 165 |
Therefore, this 300 ft, 8 ft tall chain-link fence needs approximately 39 posts (37 line / 2 terminal), 7 fabric rolls, and 47 bags of concrete.
