Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight and plain grain with a coarse, uneven texture. The end grain shows prominent, distinct growth rings with a sharp transition from earlywood to latewood.
Color Description
Heartwood is typically a yellowish to reddish-brown, while the sapwood is lighter yellowish-white. The color darkens and yellows significantly with age and light exposure. Low to medium luster.
Hardness Rating
620 lbf (Soft)
Durability Rating
Moderately Durable; generally resistant to rot and decay but susceptible to insect attack. Performs well in outdoor construction if treated.
Common Uses
Heavy structural lumber, construction framing, flooring, veneer, cabinetry, and boat building.
Geographic Origin
Western North America (Pacific Northwest) and widely planted in Europe and New Zealand.
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.50 per board foot depending on grade (Vertical Grain commands a premium).
Wood Age Estimate
Freshly cut log (less than 1 year since felling) based on the bright color, lack of significant graying/oxidation, and high moisture appearance in the fibers.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and harvested from sustainably managed forests.
Workability
Generally easy to work with hand and machine tools, though it can be prone to splintering and tearout. Glues and finishes well, but requires a sealer for even staining.
Notable Features
Features a distinct, resinous scent when worked. Known for having one of the highest strength-to-weight ratios among softwoods. High resin content can sometimes foul saw blades.
Finish Recommendations
Polyurethane, varnish, or penetrating oils. Due to uneven density between earlywood and latewood, a wood conditioner or sanding sealer is highly recommended before staining.
Identification Confidence
High. The prominent growth rings, reddish-orange hue, and rough texture from the chainsaw cut are classic indicators of Douglas Fir.
