Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Mostly straight with prominent, tight growth rings. Shows some flatsawn cathedral patterns and wavy transitions between earlywood and latewood typical of old-growth timber.
Color Description
Heartwood ranges from yellowish-tan to reddish-brown; sapwood is lighter cream. Features high contrast between light earlywood and dark reddish-brown latewood rings. Darkens to a deep orange-red patina with age.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; resistant to decay but susceptible to insect attack. Strongest of the softwoods.
Common Uses
Flooring, heavy timbers, structural framing, cabinetry, doors, and millwork.
Geographic Origin
Western North America (Pacific Northwest to British Columbia)
Market Value & Sustainability
Estimated Market Value
$5.00 - $12.00 per board foot for reclaimed old-growth/vertical grain; higher for wide planks.
Wood Age Estimate
Estimated 80-120 years old based on the tight ring density (old-growth), oxidation patina, and wear indicating early 20th-century installation.
Sustainability Status
Least Concern on IUCN Red List; widely available as FSC certified; reclaimed stocks are highly sustainable.
Workability
Works well with machines but can be prone to splintering and tearout on the end grain. Holds nails and screws well; high resin content can occasionally gum up sandpaper.
Notable Features
Distinctive resinous scent when cut; highest strength-to-weight ratio among common softwoods; pronounced contrast between growth rings.
Finish Recommendations
Polyurethane or floor-grade oils for durability. Requires sanding to remove old oxidation and surface contaminants. A wood conditioner is recommended if staining to prevent blotchiness.
Identification Confidence
High; the tight growth rings, specific reddish-brown latewood color contrast, and application as old-growth subflooring/flooring are diagnostic of Douglas Fir.
