From the height of standard chain link fence setups to the right gauge wire, this guide covers everything you need to know.
If you’re deciding boundary lines or privacy, this primer on types of fences covers materials, maintenance, and cost so you pick once and right.
A Quick History: When Was Chain Link Fence Invented?
Before diving into measurements, a bit of trivia: the chain link fence was invented in the mid-19th century in the UK and later popularized in the United States around the 1890s. Its affordability, durability, and ease of installation made it the go-to fencing option for homeowners and commercial properties alike.
Fun fact: Chain link fencing became especially popular in the U.S. after World War II, when steel production ramped up for civilian projects.
Chain Link Fence Post Size Chart
Here’s a handy chart showing recommended post sizes based on the height of standard chain link fence panels:
Fence Height | Terminal / Corner Post Diameter | Line Post Diameter | Post Depth in Ground | Recommended Gauge |
3 ft | 1 ⅝" – 2" | 1 ⅜" | 18–24" | 11–12 gauge |
4 ft | 2" – 2 ½" | 1 ⅝" | 24" | 11 gauge |
5 ft | 2 ½" – 3" | 1 ⅝" – 1 ⅞" | 24–30" | 11 gauge |
6 ft | 2 ½" – 3" | 1 ⅞" | 30" | 9–11 gauge |
8 ft | 3" – 4" | 2 ⅜" | 30–36" | 9 gauge |
The gauge refers to the thickness of the wire mesh. Lower numbers mean thicker, stronger wire. If you’re wondering what gauge chain link fence is best, 9-gauge is standard for heavy-duty residential and commercial use.
How to Build a Chain Link Fence with Proper Posts
Measure your property line – Always check with local codes and HOAs.
Mark post locations – Space line posts every 6–10 feet for stability.
Dig post holes – Follow the depth guidelines above; add gravel for drainage.
Set posts with concrete – Allow 24–48 hours to cure.
Stretch and secure mesh – Attach with tension bands, ties, and top rails.
The American Fence Association recommends using at least ⅓ of the post height below ground for maximum stability.
