Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Typically straight or slightly wavy with a flat-sawn cathedral appearance. Visible distinct transition between light earlywood and dark, dense latewood bands. Texture is medium to coarse.
Color Description
Heartwood ranges from light brown to a reddish-tan; sapwood is yellowish-white. The wood displays high contrast between growth rings and darkens to a more orange-brown patina with UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; heartwood is resistant to decay but susceptible to insect attack. Excellent strength-to-weight ratio for a softwood.
Common Uses
Heavy structural construction, framing, flooring, veneer, cabinetry, and exterior millwork. Often used for Christmas trees and utility poles.
Geographic Origin
Western North America (Pacific Northwest)
Market Value & Sustainability
Estimated Market Value
$3.00 - $6.00 per board foot depending on grade and kiln drying.
Wood Age Estimate
Modern seasoned lumber; roughly 1-5 years post-processing based on light oxidation and standard mill marks.
Sustainability Status
Least Concern (IUCN); widely available and frequently FSC-certified. Sustainable due to extensive reforestation and plantation growth.
Workability
Generally easy to work with both hand and machine tools, though it can be prone to splintering or tearing along the grain. Hard latewood bands can cause uneven sanding if caution is not used.
Notable Features
Distinctive resinous scent when cut. Known for being one of the strongest softwoods available globally. Can cause skin irritation or splinters in some users.
Finish Recommendations
Takes clear coats, oils, and lacquers well. Gel stains are recommended if color is desired, as standard stains may appear blotchy due to density variations in growth rings.
Identification Confidence
High. The prominent growth rings, color palette, and coarse grain texture are classic indicators of Douglas Fir, distinguished from pine by its lack of large resin canals and reddish-brown heartwood.
