Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Straight, vertical grain with distinct cathedral patterning in the center. The growth rings are tight and prominent, indicating old-growth or slow-growth characteristics common in vertical grain (VG) lumber.
Color Description
Heartwood ranges from yellowish-orange to a deep reddish-brown. Sapwood is yellowish-white. It exhibits a moderate luster and darkens significantly with age and light exposure (patina).
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers moderate resistance to rot and decay but is susceptible to insect attack. Excellent dimensional stability once seasoned.
Common Uses
Heavy construction, flooring, cabinetry, interior trim, boat building, veneers, and decorative beams.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
4.00 to 9.00 USD per board foot depending on grade and vertical grain premium.
Wood Age Estimate
5-15 years based on surface oxidation and the lack of deep graying/weathering, though the source tree was likely significantly older (100+ years) given tight growth rings.
Sustainability Status
Least Concern (IUCN); widely available as FSC certified; not CITES listed.
Workability
Generally easy to work with machine and hand tools. Can be prone to splintering and tearout if tools are not sharp. Holds nails and screws well but may require pre-drilling near ends.
Notable Features
Distinctive resinous, sweet scent when cut; high strength-to-weight ratio; high resin content which can cause pitch pockets.
Finish Recommendations
Clear polyurethane or lacquer to showcase grain. Sanding sealer is recommended to prevent uneven absorption of stains due to earlywood/latewood density differences.
Identification Confidence
High; the distinct transition between earlywood and latewood, the reddish-orange hue, and the characteristic straight, tight grain are diagnostic for Douglas Fir.
