Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight grain with a medium-to-coarse texture. Growth rings are prominent and generally uniform, showing a typical flat-sawn to rift-sawn orientation.
Color Description
Light brown to reddish-brown heartwood with a narrow band of yellowish-white sapwood. Shows high contrast between earlywood and latewood. Darkens slightly with UV exposure over time.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable regarding decay resistance; susceptible to insect attack.
Common Uses
Heavy structural lumber, construction framing, flooring, plywood, veneer, and trim work.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$2.50 to $5.00 per board foot depending on grade (Vertical Grain commands higher prices).
Wood Age Estimate
New/Recent stock. The clean surface, lack of oxidation, and fresh mechanical cuts suggest it is modern dimensional lumber (under 2 years old).
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List. Widely available as FSC-certified.
Workability
Generally works well with both hand and machine tools, but can be prone to splintering and tearout if tools are not sharp. Glues and finishes well.
Notable Features
Distinctive resinous scent when worked. Known for having one of the highest strength-to-weight ratios of any softwood.
Finish Recommendations
Takes stains, paints, and clear coats well. Due to uneven absorption between earlywood and latewood, a conditioner or sanding sealer is recommended before staining.
Identification Confidence
High. The prominent growth ring contrast, color, visible resin canals, and use as a structural board are classic indicators of Douglas Fir.
