Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with a characteristic coarse texture. The visible end-growth rings show a medium growth rate with a distinct transition between light earlywood and reddish-brown latewood.
Color Description
Light brown to yellowish-orange with reddish-brown latewood growth rings. Color tends to darken to a deeper reddish-brown with exposure to UV light and oxidation.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay and rot but is susceptible to insect attack if left untreated.
Common Uses
Structural timber, heavy construction, plywood, flooring, cabinetry, and exterior millwork.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$2.50 - $4.00 per board foot for select grades
Wood Age Estimate
Recently milled (under 1 year) based on the lack of oxidation, sharp edges, and light surface color.
Sustainability Status
Least Concern (IUCN); widely available and commercially farmed with FSC certification common.
Workability
Generally works well with both hand and machine tools, though latewood can be hard and may cause uneven sanding (washboarding). Glues and finishes well.
Notable Features
Distinctive resinous scent when cut and high strength-to-weight ratio for a softwood.
Finish Recommendations
Polyurethane or oil-based varnishes are recommended. A sanding sealer or pre-stain conditioner is suggested to prevent splotching or uneven stain absorption.
Identification Confidence
High; the distinct contrast between earlywood and latewood rings, the color palette, and the fibrous end-grain texture are classic indicators of Douglas Fir.
