Wood is a versatile and widely used material in construction and woodworking projects. When it comes to selecting the right type of wood for your project, it’s important to consider various factors such as strength, durability, applications, cost, and availability. In this article, we will explore the comparison between Douglas Fir and Redwood, two popular types of wood lumber, to determine which one is stronger.

Is Douglas Fir stronger than redwood?

Fir has the added advantage of being harder than redwood, making it more resistant to heavy foot traffic and dings.

Strength Comparison

Strength Characteristics of Douglas Fir

Douglas Fir is known for its exceptional strength properties, making it a preferred choice for structural applications. It has a high density and a strong, straight grain that contributes to its overall strength. The wood’s stiffness and resistance to bending make it suitable for load-bearing structures such as beams and joists. Douglas Fir also has good shock resistance, which allows it to withstand heavy foot traffic and resist dings and dents better than some other types of wood.

Strength Characteristics of Redwood

Redwood, on the other hand, is renowned for its natural beauty and durability but is not as strong as Douglas Fir. While it possesses decent strength properties, it is not typically used for heavy load-bearing applications. Redwood is often utilized in outdoor projects like decks, fences, and siding, where its natural resistance to decay and insect damage is highly valued. It offers moderate strength, but when it comes to heavy foot traffic and impact resistance, Douglas Fir tends to outperform Redwood.

Durability Comparison

The durability of Douglas Fir

Douglas Fir exhibits excellent durability, especially when treated and maintained properly. It has a natural resistance to decay and rot, which enhances its lifespan when used in exterior applications. However, without proper protection, Douglas Fir can be susceptible to weathering and moisture damage over time. Regular maintenance, such as sealing or staining, can help prolong its durability and ensure its long-term performance.

Durability of Redwood

Redwood is widely known for its exceptional durability. It contains natural oils and tannins that act as preservatives, providing resistance against decay, insects, and moisture. This inherent resistance makes Redwood an excellent choice for outdoor projects exposed to harsh weather conditions. With proper care and periodic maintenance, Redwood can maintain its structural integrity and beauty for many years.

Common Applications of Douglas Fir

Due to its strength and durability, Douglas Fir finds extensive use in various construction applications. It is commonly employed in framing, flooring, roofing, and heavy-duty structural components. Its stability and resistance to warping make it suitable for interior finishes such as doors, windows, and cabinetry. Douglas Fir‘s strength also makes it a preferred choice for the manufacturing of furniture and high-quality veneers.

Common Applications of Redwood

Redwood’s natural beauty and durability make it a popular choice for outdoor projects. It is frequently used in decking, outdoor furniture, fences, and siding. The rich color and distinctive grain patterns of Redwood add an aesthetic appeal to any landscape or garden. Its resistance to insects and decay, coupled with its ability to withstand weathering, makes Redwood an excellent option for exterior applications where longevity and visual appeal are crucial.

Common Applications of Redwood

Cost and Availability

When considering the cost and availability of Douglas Fir and Redwood, several factors come into play.

In terms of cost, Douglas Fir is generally more budget-friendly compared to Redwood. Its availability and widespread use contribute to its affordability, making it a cost-effective option for various construction projects. On the other hand, Redwood is known for its higher price point due to its limited availability and unique characteristics. The scarcity of mature Redwood trees and the time it takes for them to grow contribute to the higher cost of Redwood lumber.

Availability-wise, Douglas Fir is more readily available in the market. It is grown in many regions, making it easier to find and purchase. Redwood, on the other hand, is primarily found in specific regions, particularly along the west coast of the United States. This limited geographic distribution affects its availability in other parts of the world.


In the comparison between Douglas Fir and Redwood, it is evident that Douglas Fir possesses superior strength characteristics, making it a preferred choice for heavy load-bearing applications. Its durability and resistance to foot traffic and impact further enhance its suitability for high-traffic areas. On the other hand, Redwood excels in terms of natural beauty, durability, and resistance to decay and insects, making it an ideal choice for outdoor projects.

Ultimately, the choice between Douglas Fir and Redwood depends on the specific requirements of your project, budget considerations, and availability in your region. Both kinds of wood have their unique advantages and applications, and understanding their characteristics will enable you to make an informed decision when selecting the most suitable wood for your needs.
