Let’s look into a more detailed comparison to know more about them.

Differences Between Southern Yellow Pine And Douglas Fir

Southern Yellow Pine and Douglas Fir are two types of wood commonly used in construction and woodworking. They have distinct characteristics that make them suitable for various applications. Here are the core differences between them:

Factor 1. Strength And Durability 

Strength and durability are primary concerns when it comes to timber. Luckily, you don’t need to worry about it when it comes to southern yellow pine and douglas fir. They do, however, vary in several ways.

Southern Yellow Pine 

Southern yellow pine is one of the strongest species of softwood. It’s so strong that it’s often used as the building material for wooden roller coasters. 

When it comes to its strength, MOR is 12,800 psi when dry. It’s also very stiff with a MOE of 1.8 million psi. And the hardness is 690 pounds. 

This strength shows that this wood is perfect for structural components. So whether you are a professional or a DIY enthusiast, you’ll never go wrong with this species of wood. 

Douglas Fir 

Among softwoods, Douglas fir is very strong. However, it’s not as strong as the Southern yellow pine. 

It’s one of the few softwoods that maintain their size and shape as it ages. It dries perfectly straight. 

This ensures that the wood can be nailed up green and allowed to season in place.

Seasoning takes a short time as well. It’s particularly resistant to decay, making it a long-lasting wood.

Factor 2. Usage

Both the wood species are quite different. So is their usage. Their unique properties are what make them suitable for different purposes. 

Southern Yellow Pine

Because of its strength and incredible properties, southern yellow pine is a common option for building. This wood also dries down and glues quickly. 

Making the installation process much easier and more effective.

Many businesses use southern yellow pine to make trusses and other building framings. It is also a great option for both indoor and outdoor furniture. 

With its high density and amazing properties, you don’t need to worry about damages. Even if it’s kept in an outdoor environment. 

Douglas Fir

Since the Douglas fir is rigid and sturdy, it can be used for a variety of purposes. including masts, in wooden boatbuilding. The majority of Douglas fir available for purchase is for building and framing. 

It works okay enough for construction purposes. But using it for making benches or other utilities is a big no. 

Factor 3. Crack Resistance

To use any wood, we must make sure that it’s prone to splinters or cracks. If it’s easily susceptible to those, it might not be useful for any construction.

Southern Yellow Pine

In the case of building a bench or anything, similar southern yellow pine is a better option. You don’t want a bench with chunks cracking off of the end.

As southern Yellow Pine grows on acidic red clay soil. It’s also tolerable to most weather conditions. 

Douglas Fir

Douglas Fir is way too soft and splintery to make a good benchtop. As it tends to get splinters and cracks your bench wouldn’t probably last long. 

But you can minimize its splinters by using good quality wood protection. Here are two that you can try. 

You won’t be able to change the complete dynamic of this wood species. With a little help from these wood stains, you can definitely make them more long-lasting. 

Which Should You Choose: Southern Yellow Pine Or Douglas Fir?

Is Southern yellow pine rot-resistant?

Yes, Southern yellow pine is rot-resistant. But it is a good idea to have a protective layer for extra assurance.

Is Douglas Fir stronger than pine?

Yes, Douglas Fir is generally stronger than most pine species. Douglas Fir has a higher density and greater strength properties compared to many types of pine. It is known for its impressive load-bearing capacity, making it a preferred choice for structural applications in construction and woodworking.

How long will a Douglas fir deck last?

A Douglas fir deck will last around 10 to 25 years. However, it will be subjected to a certain level of damage during this time span. 


I hope you found this article to be informative. I made every effort to provide you with all of the pertinent information that will be of assistance to you. So that you understand the differences between Southern yellow pine vs Douglas Fir.
