Chain link fence calculator
Calculate line posts, terminal posts, top rail and concrete for a chain link fence run, with 10 foot post spacing as the default.

Overview
Chain link fences typically run on wider post spacing than wood, commonly 10 feet, since the fabric itself carries very little of its own weight between posts. This calculator defaults to that spacing and a standard style when chain link is selected, with height and everything else still fully editable.
The post, corner and end counts, and the concrete formula, work the same way as any other material here: they are computed from your actual run length and spacing, not a fixed number per typical yard.
Common mistakes
- Assuming chain link needs no concrete because it is lightweight; terminal and corner posts still carry real tension from the fabric and need a proper footing.
- Using wood-fence post spacing (8 feet) instead of the wider spacing chain link fabric is designed for, which adds unnecessary posts and cost.
- Forgetting a top rail or tension wire in the hardware count when planning fabric.

Frequently asked questions
Why is the default post spacing 10 feet instead of 8?
Chain link fabric distributes tension differently than wood panels, so it commonly runs on wider spacing, typically 10 feet, without sagging. You can still set any spacing you want in the calculator.
Does chain link still need concrete footings?
Yes, especially at corner, end and gate posts, which carry the tension of the stretched fabric. This calculator computes concrete for every post the same way regardless of material.
How many bags of concrete does a chain link post need?
The same volume math as any fence post: hole diameter and depth set the volume, and this calculator converts it to 50, 60 and 80 lb bag counts. A typical 10 inch by 24 inch hole needs about 2.5 to 3 bags of 60 lb mix.
Do I need a top rail on a chain link fence?
Usually yes on a residential chain link fence: the top rail ties the posts together and keeps the fabric edge straight. Tension wire along the bottom is the common companion under the fabric.
What post size does a chain link fence use?
Residential chain link commonly uses schedule-40 pipe: line posts around 1.5 to 1.875 inches, with heavier terminal and corner posts. Many systems spec 2 inch terminal posts; follow the manufacturer table for your height and spacing.
How tall can a chain link fence be?
Residential heights commonly run 4 to 6 feet, and 8 feet is available for sport or deer exclusion. Taller fabric catches more wind, so confirm post size and spacing for the height you choose.
How much does a chain link fence cost?
Chain link is usually the least expensive material per linear foot among the common options, and the exact number depends on height, gauge of fabric, and local prices. Enter your own unit prices in this calculator for a total tied to your numbers.
Which gauge of chain link fabric should I use?
Residential fabric commonly runs 11.5 to 9 gauge, with heavier gauge (lower number) costing more and resisting damage better. For pet or security fencing the mid gauge is a good balance; the calculator's material math does not depend on gauge, but your quote will.
