Typically, fence posts are available in two sizes: 2 3/8-inches for corner and end posts, and 1 5/8-inches for line posts or other posts within the fence. However, before you even get to installing the posts, it’s essential to understand the proper technique for digging post holes.

What Diameter Are Fence Posts?

The diameter of a metal fence post depends on the type of post it is. Typically, fence posts come in two diameters: 2 3/8 inches and 1 5/8 inches. The wider diameter of 2 3/8 inches is commonly used for the corner and end posts of the fence. These posts need to be sturdy and able to support the weight and tension of the fence.

On the other hand, the smaller diameter of 1 5/8 inches is used for line posts or the other posts in the fence. These posts don’t bear as much weight or tension as the corner and end posts, so a smaller diameter is sufficient. It’s important to choose the appropriate diameter for each post to ensure the overall stability and strength of the fence.

When building a chain-link fence, one of the crucial steps is digging the post holes correctly. This will greatly impact the stability and durability of the fence. The depth and diameter of the post holes should be suitable for the size and type of posts being used. The wider diameter posts will require larger holes to accommodate their size.

To determine the diameter of the post holes, it’s essential to consult the manufacturers instructions or guidelines. It’s crucial to follow these instructions to ensure the proper installation of the fence and to prevent any issues in the future.

Taking the time to dig post holes of the correct diameter will greatly contribute to the longevity and effectiveness of the fence, providing security and privacy for years to come.
