Quick Answer: Dimensional lumber typically runs $0.30 to $1.50 per linear foot (LF) for 2x4 through 2x12 in common species as of 2026, with engineered and treated products running higher. Stud grade 2x4 lands near $0.40 to $0.65 per LF, select structural 2x12 can reach $2.50 to $4.00 per LF. Your real cost moves with species, grade, length, treatment, and the lumber commodity index, so price every bid from current lumberyard quotes, not a list price.
What Drives the Price
Lumber is a commodity, but the number on your quote is set by six variables that every estimator should know cold.
- Species: SPF (spruce pine fir) is the default framing lumber in the northeast and upper midwest and runs cheapest. Southern Yellow Pine (SYP) is the default in the south and southeast, denser and stronger, slightly higher per board foot. Douglas Fir and Hem Fir dominate the west coast and mountain states and run higher still, especially in long lengths. Cedar and redwood for trim, decking, and fencing run 2 to 4 times SPF.
- Grade: Stud grade and #2 are the workhorses for framing. #1 and Select Structural (SEL STR) carry fewer knots and higher bending values, and they cost 15% to 40% more per board foot. Machine stress rated (MSR) and machine evaluated lumber (MEL) for joists and rafters run higher because every piece is proof loaded. Construction, Standard, and Utility grade show up in non structural blocking and run cheaper, but you cannot use them in load bearing framing.
- Length: 8, 10, 12 foot lengths are commodity and carry the lowest per foot price. 14, 16, 20 foot lengths cost more per board foot because they are cut from larger logs. 24 foot and longer 2x12 for long span joists and beams can run 50% to 150% more per board foot than 12 foot of the same size.
- Treated vs plain: Pressure treated southern yellow pine (PT, ground contact, 0.25 or 0.40 pcf retention) for plates in contact with concrete, sills, and exterior framing adds 30% to 70% over plain SYP. Treated deck boards run $1.20 to $2.50 per LF for 5/4x6. Fire retardant treated (FRT) for type III and type V rated construction runs 2 to 3 times plain lumber.
- Engineered alternatives: LVL, PSL, LSL, and I joists replace solid sawn in long span and high load applications and are priced per LF or per piece, not per board foot. See the LVL and engineered lumber guide for those ranges.
- Commodity index: Random Lengths Framing Lumber Composite and the CME lumber futures move weekly. A 2x4 that cost $0.45 in March can cost $0.80 in July or $0.35 in October. A lumberyard quote older than 30 days is a guess.
Typical Price Ranges by Size and Type
Use these as a typical range in most US markets as of 2026. SPF framing in the northeast and SYP in the south will land at opposite ends. Always confirm with your local yard.
- 2x4 stud grade, 8 to 10 ft: $0.40 to $0.70 per LF.
- 2x4 #2, 8 to 12 ft: $0.45 to $0.75 per LF.
- 2x6 #2, 8 to 12 ft: $0.65 to $1.05 per LF.
- 2x8 #2, 8 to 16 ft: $0.95 to $1.80 per LF.
- 2x10 #2, 8 to 16 ft: $1.25 to $2.50 per LF.
- 2x12 #2, 8 to 16 ft: $1.50 to $3.00 per LF.
- 2x12 select structural, 20 to 24 ft: $3.00 to $4.50 per LF.
- Pressure treated 2x6, 8 to 12 ft: $0.95 to $1.60 per LF.
- Pressure treated 5/4x6 deck board: $1.20 to $2.50 per LF.
- Engineered I joist, 9.5 to 16 inch depth: $1.80 to $4.50 per LF.
- OSB and plywood sheathing: see the plywood and OSB guide, typically $9 to $18 per 4x8 sheet.
For board foot pricing, divide LF by 12 and multiply by nominal thickness times nominal depth in inches. A 2x4 at $0.55 per LF equals roughly $0.55 / 0.67 BF = $0.82 per board foot. Suppliers quote both ways, so keep both numbers in the bid.
How to Buy Smarter
Lumber is bought by the bundle from a lumberyard or by the load from a reload facility. The unit price is the headline, the loaded cost is what kills margin.
- Get three lumberyard quotes dated within the bid week. Yard prices vary 10% to 30% on the same commodity because of freight, inventory, and backlog. A quote older than 30 days is a guess.
- Order in bundle multiples. Studs ship in unit bundles of roughly 254 to 294 pieces. Plates and joists ship in lifts of 1,000 to 2,000 board feet. Partial bundle premiums and broken bundle fees add $50 to $200 per bundle, so consolidate the takeoff to whole bundles where you can.
- Specify species, grade, and length. A vague "2x4 framing" line item lets the yard bid the cheapest compliant grade. If you need #2 stud, long lengths, or MSR joists, write it into the quote request so every yard prices the same thing.
- Lock the price for the framing window. On bids with framing 60 to 120 days out, ask the yard to hold price for 30 days or to quote with a stated escalator. Vague "subject to market" language is where estimates leak on lumber.
- Buy pre cut studs for standard walls. Pre cut 92 5/8 inch studs for 8 foot ceilings and pre cut 104 5/8 inch studs for 9 foot ceilings trim waste and labor compared to cutting full 8 or 10 foot studs on site.
- Consolidate species and sizes. A frame that mixes Douglas fir and SYP, or four different joist depths, costs more than a frame standardized on one species and two depths. Standardize where the design allows.
Where Estimators Get It Wrong
The classic mistake is pricing by the piece and forgetting the bundle. You bid 5,000 LF of 2x4 at $0.55 and feel smart, then the broken bundle fees, the long length premiums, the treated plate upgrade, and the delivery charges add 8% to 18% to the loaded cost. Lumber is cheap per LF and expensive per square foot of frame once you load it.
The second mistake is using last month's lumber price on a job that frames next quarter. The Random Lengths composite moves weekly. Refresh quotes within 30 days of the framing window.
The third is ignoring grade and length upgrades in the field. The framer asks for #1 or select structural for a long span header, or 20 foot lengths for a vault, and you absorb the upgrade without a change order because the spec allowed it. Lock the grade and length in writing and price any upgrade as a documented change.
The fourth is underestimating waste. A 10% waste factor is the minimum for wall and floor framing. Hip and valley roofs, irregular shapes, and heavy stud packing at corners and intersections push it to 15%. A cheap unit price with a tight waste factor loses money. A slightly higher unit price with an honest waste factor makes money.
Putting It Together
Build your lumber line item from the ground up: LF by size and species from the takeoff, plus a 10% to 15% waste factor rounded up to whole bundles, times the current delivered unit price for the exact grade, species, and length you specified, plus the treated plates as a separate line, plus the delivery and broken bundle fees. That is your installed framing cost per square foot, and it is the only number that matters on buyout day. Get three yard quotes dated this week, specify the grade and length, lock the price window, and refresh before the framing window opens. Do that and your lumber budget holds.
