Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Strong cathedral grain figure with prominent latewood bands. Flat-sawn orientation showing wide, wavy growth rings and distinct transition between earlywood and latewood.
Color Description
Natural heartwood ranges from light reddish-brown to orange; sapwood is yellowish-white. This sample has a darkened amber/reddish-brown patina and is likely stained. It darkens significantly with age and light exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack if untreated.
Common Uses
Flooring, heavy construction (glu-lam beams), cabinetry, millwork, and veneer.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $7.00 per board foot depending on grade and whether it is reclaimed old-growth.
Wood Age Estimate
Estimated 40-70 years based on the tight growth rings indicative of old-growth timber and the deep oxidation/ambering of the finish.
Sustainability Status
Generally sustainable; not CITES listed. FSC certification is common for this species.
Workability
Generally easy to work with machine and hand tools, though the difference in hardness between earlywood and latewood can cause uneven sanding and 'washboarding'. Holds glue and finish well.
Notable Features
Distinctive resinous scent when cut; known for having the highest strength-to-weight ratio of any softwood species.
Finish Recommendations
Oil-based polyurethane or lacquer to maintain the amber tone. Requires a sanding sealer or wood conditioner before staining to prevent blotching due to uneven density.
Identification Confidence
High; the wide, dark latewood bands and specific cathedral patterns are classic markers for flat-sawn Douglas Fir, specially used in mid-century flooring or utilitarian furniture.
