Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, fine to medium-textured grain with prominent, darker latewood bands resulting in a visible flat-sawn ring pattern on the face grain. Tight growth rings indicate old-growth or high-altitude harvesting.
Color Description
Heartwood ranges from light reddish-brown to a yellowish-tan color with clearly defined, darker growth rings. Sapwood is a lighter creamy white. It tends to darken or redden significantly with exposure to UV light and air.
Hardness Rating
660 lbf (Soft to Medium-Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack. Performs well in outdoor applications if properly treated or maintained.
Common Uses
Heavy timber construction, residential framing, flooring, cabinetry, veneer, boat building, and structural beams due to its high strength-to-weight ratio.
Geographic Origin
Native to Western North America, predominantly the Pacific Northwest ranging from British Columbia down to California and the Rocky Mountains.
Market Value & Sustainability
Estimated Market Value
$3.00 to $7.00 per board foot depending on grade (Vertical Grain vs. Flat Sawn) and local availability.
Wood Age Estimate
The raw, rough-sawn state suggests it was milled within the last 1-5 years, though the tight growth rings indicate the tree itself was likely 80-150 years old at the time of harvest.
Sustainability Status
Extensively managed and generally sustainable. Not listed in CITES Appendices or on the IUCN Red List. FSC certification is common and widely available for this species.
Workability
Generally works well with both hand and machine tools. It can be prone to splintering and tearout if tools are not sharp. Holds glue, nails, and screws well, though high resin content can occasionally gum up sandpaper and saw blades.
Notable Features
Features a distinct, resinous, and sweet evergreen scent when cut. Known for being one of the strongest softwoods available globally. Contains high levels of resin which can bleed through finishes if not sealed.
Finish Recommendations
Resin-based finishes or penetrative oils work best. If staining, a pre-stain wood conditioner is highly recommended to prevent blotchiness. Polyurethane provides excellent protection for high-wear areas like flooring.
Identification Confidence
High. The combination of prominent reddish-brown latewood bands, fine grain texture, light-colored sapwood edge, and the characteristic rough-sawn appearance is classic for Douglas Fir harvested in North America.
