Red Oak
Scientific Name: Quercus rubra
Overview
Red Oak is one of the most widely distributed and commercially important hardwoods in North America. Native to the eastern and central United States and parts of southeastern Canada, it is valued for its strength, availability, and distinctive open grain.
Red Oak is commonly used in flooring, cabinetry, and interior millwork. Its pronounced grain pattern and relative affordability make it a staple species in both residential and commercial applications.
Quick Facts
- Common Name: Red Oak
- Scientific Name: Quercus rubra
- Region: North American Hardwoods (Eastern United States & Canada)
- Tree Size: 60–100 ft tall, 2–4 ft trunk diameter
- Average Dried Weight: 44 lbs/ft³ (705 kg/m³)
- Janka Hardness: 1,290 lbf
- Color: Light to medium reddish brown
- Grain: Straight, open grain
- Texture: Coarse
Identification Characteristics
Red Oak is best identified by its prominent ring-porous structure and coarse texture. Earlywood pores are large and form a distinct row along each growth ring, creating a strong grain pattern.
The heartwood ranges from light brown to reddish brown. When examining end grain, Red Oak’s pores remain open and visible, often appearing as continuous lines across the growth ring.
Key identification traits include:
- Reddish brown coloration
- Large earlywood pores forming clear rings
- Coarse, open grain
- Visible ray fleck when quartersawn
Working Properties
Red Oak machines well and is relatively easy to work with standard tools. Its open pores make it receptive to stains, though grain filling may be required for a smooth finish.
- Machines and sands well
- Stains readily
- Glues reliably
- Accepts finishes well
- May require grain filler for smooth surfaces
Safety Note
Red Oak has low reported toxicity. Wood dust may cause mild irritation. Standard dust protection is recommended.
Common Uses
Red Oak is commonly used in:
- Hardwood flooring
- Cabinetry
- Furniture
- Interior trim
- Stair treads
- Doors
- Veneer
Sustainability & Notes
Red Oak is widely available and sustainably harvested throughout its range. It remains one of the most economically important hardwood species in North America.
Due to its open pore structure, Red Oak is not considered naturally rot-resistant and is generally limited to interior applications.

Collector Notes
While Red Oak is common, quartersawn material displaying strong ray fleck can be visually striking. This figure is especially valued in mission-style furniture.
Color variation and growth rate can differ by region, affecting density and grain prominence.
