Douglas Fir

Pseudotsuga menziesiiSoftwood

Douglas Fir

Grain Pattern

Generally straight and plain; very tight growth rings visible due to slow-growth or vertical grain cut; some light wavy figure possible but typically uniform and linear.

Color Description

Heartwood ranges from light brown to reddish-brown; sapwood is a yellowish-white. Wood tends to darken to a deeper orange-red or reddish-brown over time with exposure to UV light.

Hardness Rating

660 lbf (Soft)

Durability Rating

Moderately Durable; offers moderate resistance to rot and decay but is susceptible to insect attack.

Common Uses

Structural framing, heavy timber construction, flooring, cabinetry, interior trim, veneer, and boat building.

Geographic Origin

Western North America (Pacific Northwest into Canada)

Market Value & Sustainability

Estimated Market Value

$3.00 - $6.00 per board foot for Select/Vertical Grain grades.

Wood Age Estimate

Modern kiln-dried lumber, likely under 5 years since harvesting based on the clean, light coloration and lack of oxidation patina.

Sustainability Status

IUCN category - Least Concern; widely available as FSC certified and primarily sourced from managed forests.

Workability

Generally easy to work with both hand and machine tools, though it can split when nailing or screwing near edges. It takes glue and finishes well but may require a sealer for even staining.

Notable Features

Distinctive resinous scent when cut; has a very high strength-to-weight ratio for a softwood; distinct transition between earlywood and latewood rings.

Finish Recommendations

Clear polyurethane, lacquer, or oils like Danish oil. Using a wood conditioner or sanding sealer is recommended before staining to prevent blotchiness.

Identification Confidence

Medium-High; the reddish-tan hue, prominent vertical grain, and presence of small fibrous tearout are classic identifiers of vertical-grain Douglas Fir lumber.
