8/4 walnut typically costs about $7-$18 per board foot at U.S. lumberyards, with many standard kiln-dried boards priced near $11 per board foot. Board grade, width, drying, surfacing, order size, and local availability can shift the quote; figured or unusually wide stock may cost more.

What 8/4 walnut lumber costs per board foot
For ordinary domestic black walnut, a practical budget is $7-$18 per board foot for rough, kiln-dried 8/4 stock. A common middle quote is about $11 per board foot, while surfaced boards often land around $9-$23 per board foot. These are planning ranges, not fixed national list prices; a local yard may price by board foot, piece, or bundle.
8/4 means lumber is nominally 2 inches thick before surfacing. It is not necessarily 2 inches thick when delivered: rough stock may vary, and planing both faces reduces its finished thickness. Confirm the yard’s minimum thickness and whether the quoted price covers rough lumber, S2S (surfaced two sides), or S4S (surfaced four sides).
One board foot is a volume measure: 1 inch thick by 12 inches wide by 12 inches long. For 8/4 stock, an approximate calculation is thickness in inches × width in inches × length in inches ÷ 144. A 2-inch-thick, 8-inch-wide, 8-foot-long board measures about 10.7 board feet before any yard-specific rounding or tally rules.
For a typical project, budget around $11 per board foot for rough stock and more for surfacing, selection, or unusually attractive grain. A 30-board-foot purchase at that midpoint is about $330 before sales tax and any delivery or milling fee.
How grade, drying, and milling shape the walnut quote
The lumber price is only one part of a finished project’s material bill. A yard may quote a per-board-foot price for the wood, then add surfacing, straight-line ripping, delivery, or a small-order charge. Ask whether the quote uses the board’s rough dimensions or its surfaced dimensions, since that affects both the tally and the usable material.
| Quote component | Low | Average | High | What changes the charge |
|---|---|---|---|---|
| Rough kiln-dried walnut | $7/bf | $11/bf | $18/bf | Grade, width, color, and supplier stock |
| S2S or S4S surfacing | $1/bf | $3/bf | $6/bf | Shop minimum, finished thickness, and surface condition |
| Cutting or straight-line ripping | $10/job | $25/job | $60/job | Number of cuts and machine setup |
| Local delivery | $25 | $60 | $150 | Distance, order size, and truck access |
| Sales tax | 0% | 6%-8% | 10%+ | Local and state tax rules |
These service prices are broad estimates; some yards include basic milling in a higher per-board-foot price, while others charge a minimum shop fee. Lumber grading also matters. Common grades can include knots and defects that reduce clear yield, whereas select or premium boards cost more but may better suit visible furniture parts.
For paid milling, a rough labor estimate can be understood as . If shop labor is billed at $60-$120 per hour, a 30-minute setup and milling job could add roughly $30-$60, subject to minimum charges. Ask for a written breakdown rather than assuming that a per-board-foot quote includes every service.
Compare the delivered, usable-board cost—not just the advertised lumber rate. A lower rough price may cease to be the better deal if surfacing, waste, or transport costs are higher.
Why board width, length, and drying alter 8/4 prices
Width is a major price driver because wide, clear walnut is less common than narrow stock. Boards wider than about 10-12 inches may carry a premium, particularly when they are long, straight, and free of large defects. A yard may also sell those pieces individually instead of at its standard per-board-foot rate.
Length affects both cost and yield. A 10-foot board can be useful for long table parts, but it may be less available and more expensive than shorter pieces. For a project needing parts under 6 feet, buying longer stock can leave costly offcuts. Conversely, a long component may require extra length for trimming checks at the ends.
Moisture condition matters too. Furniture-grade walnut is generally kiln-dried, but buyers should ask about moisture content and storage. A board at roughly 6%-8% moisture content is commonly suitable for conditioned indoor furniture work, though climate and shop conditions affect the target. Air-dried or improperly stored lumber may need acclimation and can move after machining.
Figure and color selection change the quote beyond standard grade. Highly figured grain, consistent dark color, or matching boards for a tabletop can push prices into the $18-$50-plus per-board-foot range. Matching is a selection service, not merely a wood species charge, and some yards require buying extra boards to provide a coordinated set.
For a realistic estimate, specify thickness, minimum width, usable length, grade, moisture condition, and whether boards need to match. If the request is simply “8/4 walnut,” the supplier may choose stock that does not meet the project’s appearance or yield needs.
What three 8/4 walnut projects may cost
Project totals depend on the quantity bought, not just the finished dimensions. Woodworkers commonly purchase extra for defects, trimming, layout, and grain matching. The examples below assume rough kiln-dried stock at $11 per board foot and show a modest allowance for milling or delivery; tax is excluded.
| Project scenario | Wood quantity | Wood price | Other charges | Estimated total |
|---|---|---|---|---|
| Small stool or cabinet parts | 18-22 bf | $198-$242 | $25-$75 | $223-$317 |
| Dining table components | 50-65 bf | $550-$715 | $60-$180 | $610-$895 |
| Matched, figured tabletop stock | 45-60 bf | $810-$1,800 at $18-$30/bf | $75-$200 | $885-$2,000 |
For a small cabinet, 20 board feet at $11 costs about $220; adding a $40 surfacing charge and $30 delivery brings the estimate to $290 before tax. A table project needing 58 board feet at $11 is about $638 for lumber, but a careful grain match may raise the wood rate or require purchasing several extra board feet.
A quote for a figured tabletop should state whether the premium applies to all boards or only the selected faces. Some suppliers sell matched sets at a package price. The package may look more expensive per board foot but reduce the risk of buying extra stock that does not match.
Use rough board-foot quantities for planning, then add a project-specific waste allowance. Around 10%-20% extra is a reasonable starting point for straightforward parts; complex layouts, defect-heavy boards, or matched panels may require more.
How regional hardwood markets shift walnut pricing
Walnut is harvested and processed in multiple U.S. regions, but local inventory, freight, and retailer competition influence the final price. Buyers near hardwood suppliers in the Midwest or Appalachian region may find more choices and lower transport costs. In remote areas or markets dependent on shipped specialty lumber, delivered prices can run roughly 10%-25% above a comparable local-yard quote.
Large metropolitan markets may have higher shop labor and delivery charges than rural yards. A regional difference of about 5%-15% in the total bill is plausible, but it is not a guaranteed premium: a well-stocked city yard can be cheaper than a rural retailer with limited inventory. Compare quotes using the same grade, moisture condition, surface state, and board dimensions.
Freight can be especially important for small orders. A $75 delivery fee adds $3.75 per board foot to a 20-board-foot purchase, but only $1.25 per board foot to a 60-board-foot order. Ask about pickup, shared delivery routes, or a minimum order for free or reduced delivery before choosing a supplier farther away.
Local availability and order size can outweigh broad regional averages. Request a delivered quote for the exact quantity and compare it with a nearby yard’s pickup price.
When walnut milling, delivery, and waste add to the bill
Rough lumber requires more work before it becomes furniture-ready. S2S milling flattens two faces; S4S also squares the edges, although the boards may still need final dimensioning. Typical additions of $1-$6 per board foot are possible, and small jobs may face a $20-$60 minimum even if the per-foot rate is low.
Waste is another hidden expense. A rough board may contain checks, sapwood, knots, or wane that cannot be used for a particular part. If a project requires 30 board feet of finished parts and the selected boards yield 80%-90%, the purchase may need to be about 34-38 board feet. A highly selective matching requirement can lower yield further.
Delivery, loading, and handling also vary. Local delivery commonly falls around $25-$150, while long-distance freight can be substantially higher and may include liftgate or residential delivery fees. Confirm whether the driver will unload the lumber and whether the boards must be collected at a terminal.
Some yards offer rough-cut services, thickness planning, or custom selection as separate line items. Do not pay for surfacing that the project does not need, but avoid assuming rough boards are ready for glue-up. For a flat tabletop, milling and acclimation are part of achieving stable, aligned stock.
Estimate the usable yield and every service charge before comparing two suppliers. A lower raw-board price can be offset by extra waste, higher shop minimums, or a delivery fee that is large relative to the order.
How to reduce an 8/4 walnut order without losing yield
Start with a cut list that distinguishes visible parts from hidden components. Use premium or matched walnut where color and figure matter, and consider a lower grade for concealed stretchers or drawer parts. This prevents paying a selection premium on every board while preserving the appearance of exposed surfaces.
Choose board lengths and widths around the actual parts. If the cut list uses pieces under 6 feet, ask for shorter stock rather than paying extra for long boards. A wider board can be economical when it yields several parts, but it may be wasteful when the design needs only narrow strips.
Compare rough and surfaced quotes on an equal basis. If the shop has a planer and jointer, rough lumber may save money; without suitable equipment, a surfaced quote can avoid additional tool costs and milling charges. Verify the actual thickness after surfacing, especially when the project requires full 2-inch material.
Combining a walnut purchase with another project or customer can spread a delivery fee and possibly meet a quantity discount threshold. Before buying a large bundle, confirm that the boards have the needed grade and dimensions. A discount on unusable stock is not a saving.
The most reliable savings come from controlling selection requirements, waste, and paid processing. Keep a modest reserve for defects, but avoid buying extra premium stock without a clear need.
