Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Predominantly straight grain with prominent flat-sawn cathedral patterns showing sharp contrast between earlywood and latewood. Features fine to medium texture.
Color Description
Heartwood is typically light brown with a hint of red or yellow; sapwood is a paler cream color. It exhibits high contrast between growth rings and tends to darken/redden significantly with age and UV exposure.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; resistant to rot and decay but susceptible to insect attack. Strongest of the common softwoods.
Common Uses
Structural timber, heavy construction, plywood, flooring, interior trim, cabinetry, and boat building.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains)
Market Value & Sustainability
Estimated Market Value
$4.00 - $12.00 per board foot depending on grade (Vertical Grain/CVG is higher value)
Wood Age Estimate
Modern processing, likely 1-10 years based on the crispness of the grain and lack of deep oxidation or heavy patina.
Sustainability Status
Least concern; widely available and harvested from sustainably managed forests; FSC certification is common.
Workability
Generally works well with both hand and machine tools, though it can be prone to splintering and tearout during machining. High resin content can clog sandpaper and blades.
Notable Features
Distinctive resinous, sweet odor when worked. Known for its high strength-to-weight ratio and prominent latewood lines.
Finish Recommendations
Takes clear coats, lacquer, and polyurethane well. Can be difficult to stain evenly due to density differences in the grain; a pre-stain conditioner is recommended.
Identification Confidence
High; the distinct 'cathedral' flat-sawn grain, sharp transition between light earlywood and dark latewood, and orange-to-light-brown coloration are classic hallmarks of Douglas Fir.
