How to choose the best fence post diameter

Once you have selected the type of fence you want to install, it’s time to choose the best post diameter to support that fence.

The post diameter is actually integral to building a fence because that will be the entire fence’s foundation. If you have a poor post diameter, your fence will likely sustain more damage.

It’s very important to determine the long-term goals of your fence - what’s its main use? How long do you want it to last? What can cause the most damage? What kind of fence is it?

Basically, the fence’s characteristics will impact its ideal post size.

By taking this into consideration, you can start to think about how to find the best balance between enhancing the functionality of your fence and how cost-effective its installation will be.

General Rule of Thumb

All posts should be taller and thicker than the fencing materials. By doing so, you are developing a well-built foundation. It contributes to the overall sturdiness and durability of your fence.

For example, if the fence’s height is 6 to 10 feet with 1 or 2 inches in thickness, it’s recommended that your posts are 4 by 4 inches with additional length to bury in the ground.

Fence Post Spacing

The spacing between posts plays a part in determining the best post diameter too. The closer together they are, the stronger the fence will be. If you have less space in between posts, the thickness won’t need to be as great. But the more space there is, the thicker your posts should be.

Natural factors such as weather, wear and tear, or animals can impact the longevity of the fence, but with a solid foundation, it’s less likely.

Fence Post Materials Matter

Consider the material of your fence posts. Certain types of wood won’t withstand damage such as cedar, for example.

Douglas fir, oak and #1 southern yellow pine are very strong wood species that can sustain cracking and bending, also easily located.

Store-bought treated wood posts are a great option and look neat and tidy. They’re resistant to rotting and usually don’t require frequent replacing or maintenance. They can be expensive depending on the number of posts you need, but reliable nonetheless.

If you take these factors into account when starting to find posts for your fence, you will be able to make a more informed decision.
