Common Name(s): White Oak

Scientific Name: Quercus alba

Distribution: Eastern United States

Tree Size: 65-85 ft (20-25 m) tall, 3-4 ft (1-1.2 m) trunk diameter

Average Dried Weight: 47 lbs/ft3 (755 kg/m3)

Specific Gravity (Basic, 12% MC): .60, .75

Janka Hardness: 1,350 lbf (5,990 N)

Modulus of Rupture: 14,830 lbf/in2 (102.3 MPa)

Elastic Modulus: 1,762,000 lbf/in2 (12.15 GPa)

Crushing Strength: 7,370 lbf/in2 (50.8 MPa)

Shrinkage:Radial: 5.6%, Tangential: 10.5%, Volumetric: 16.3%, T/R Ratio: 1.9

Color/Appearance: Heartwood is a light to medium brown, commonly with an olive cast. Nearly white to light brown sapwood is not always sharply demarcated from the heartwood. Quartersawn sections display prominent ray fleck patterns. Conversely, Red Oak tends to be slightly redder, but is by no means a reliable method of determining the type of oak.

Grain/Texture: Grain is straight, with a coarse, uneven texture. 

Endgrain: Ring-porous; 2-4 rows of large, exclusively solitary earlywood pores, numerous small to very small latewood pores in radial arrangement; tyloses abundant; growth rings distinct; rays large and visible without lens; apotracheal parenchyma diffuse-in-aggregates (short lines between rays).

Rot Resistance: Rated as very durable; frequently used in boatbuilding and tight cooperage applications.

Workability: Produces good results with hand and machine tools. Has moderately high shrinkage values, resulting in mediocre dimensional stability, especially in flatsawn boards. Can react with iron (particularly when wet) and cause staining and discoloration. Responds well to steam-bending. Glues, stains, and finishes well.

Odor: Has a tell-tale smell that is common to most oaks. Most find it appealing.

Allergies/Toxicity: Although severe reactions are quite uncommon, oak has been reported as a sensitizer. Usually most common reactions simply include eye and skin irritation, as well as asthma-like symptoms. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: Abundant availability in a good range of widths and thicknesses, both as flatsawn and quartersawn lumber. Usually slightly more expensive than Red Oak, prices are moderate for a domestic hardwood, though thicker planks or quartersawn boards are slightly more expensive.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Cabinetry, furniture, interior trim, flooring, boatbuilding, barrels, and veneer.

Comments: White Oak is the state tree of Connecticut, Illinois, and Maryland. Connecticut’s state quarter was minted with a picture and inscription of a famous White Oak tree, The Charter Oak.

White Oak is strong, beautiful, rot-resistant, easy-to-work, and economical, representing an exceptional value to woodworkers. It’s no wonder that the wood is so widely used in cabinet and furniture making.

Scans/Pictures: You can see from the picture below that the color of White Oak looks almost identical, though slightly darker, with sanding sealer applied. However, the grain and pores become much more pronounced if a pigment stain is used.

    Hello. I’ve recently acquired this beautiful side board (dated approximately 1910-1915). I’m going to bring it back to life and I’m wondering what type of wood it is. Oak, Cherry? Also, what stain would you recommend for restaining the top and mirror area.
    Thank you.

      Can’t tell from that picture, sorry!

      From what I can tell from this picture it looks like walnut

    I am thinking of using White Oak in lieu of Cypress for rebuilding my exterior porch railing. I know that White Oak can be stained, but can it be painted to a nice smooth finish?

      Cypress has excellent rot resistance and will hold up much better in exterior conditions but to answer your question: Oak in general is not a very friendly wood to paint if you are looking for a smooth surface. The grains are very open and porous so you will still see the graining even after being painted. Hard Maple is a much better wood if you are looking for a smooth finish paint job and it is just as strong as White Oak. Make sure it is Hard Maple as there are soft maple woods as well. The other option if you are stuck on White Oak, is to buy the highest grade (select & better or even quarter sawn oak) which will have much tighter graining pattern but this will cost you 2-3x as much for regular Oak. The graining pattern should dissipate after a few coats of paint since the paint will fill in the porous grains the more coats you put on. I might add that I would cringe to see someone paint quarter sawn oak as it is so beautiful when stained and finished properly.

      Hope this helps,

        White oak is not difficult to paint to a smooth finish, so long as it is well sanded. It doesn’t absorb the paint nearly as much as red oak, as its grain is MUCH tighter. But, that said, I would suggest not painting high quality expensive hardwoods in general — you’re covering up half of what you are paying for. Softwoods actually tend to expand less than hardwoods due to moisture exchange, which is one of the reasons they are used often in exterior builds. Plus, they tend to be less expensive, and paint easily. You’ll likely pay $5.50+ per board foot of flatsawn white oak, or roughly double for quartersawn (NEVER put paint on quarter sawn white oak). I would recommend Douglas fir for its hardness and ease of painting (which will look exactly the same once painted, since it has paint on it). For that you’ll pay about $1 per board foot.

    How stable would true American white oak be in instruments, such as guitar body’s? It seem to have a high shrinkage rate, but if it is quarter swan would or will that apply assuming that it has been properly dried?

    Fantastic writing ! Apropos , if your business requires a IRS 4868 , my business partner filled out a sample version here https://goo.gl/jyjFyS.

    I always found the same but i think is just because the grain sometimes has ondulations. If you peel the bark of a holm oak(quercus ilex) you will see it more clearly. Those parts seem to have bad grain but they never gave problems to me when doing steam bending of kayak ribs ;)

    So…. Isn’t “Quercus Alba” actually the Japanese white oak?
    This articles says its from the US. Is all white oak lumped into a
    generalized category?

      Quercus alba is definitely a Stars ‘n Stripes native. The term White Oak can be a more generalized term, but Quercus alba is very specific, and it’s native to eastern sections of North America.

      Maybe the tree has been subsequently planted in Japan too?
