Framing calculator: studs, plates, sheathing and labor cost
Figure one stud per foot of wall at 16 inch on center once kings, jacks, corners and blocking are counted, so 100 feet of wall takes about 100 studs at $3.60 to $5.60 each in 2026. This framing calculator adds three rows of plate in 16 foot 2x4s, 7/16 OSB sheets with 10 percent waste, and framing labor at $1.00 to $1.90 per square foot of wall. At the defaults, a 100 foot run of 8 foot exterior wall comes to $2,270 to $3,931 framed and sheathed.
Worked example: 100 ft wall length, 8 ft wall height, 3 rows plate rows, 100 % wall sheathed
That takes 100 studs (Studs needed). National-average costs:
| Line | Quantity | Cost range |
|---|---|---|
| 2x4 studs, 92-5/8 inch precut | 100 studs | $360 to $560 |
| 2x4 plate stock, 16 foot | 21 boards | $181 to $286 |
| 7/16 OSB wall sheathing | 28 4x8 sheets | $560 to $868 |
| Wall framing labor | 800 sq ft of wall | $800 to $1,520 |
| Sheathing labor | 800 sq ft sheathed | $280 to $560 |
| Framing nails, sill seal, anchor bolts, straps and hurricane ties | 8% | $88 to $137 |
| Estimated total | $2,270 to $3,931 |
Enter the total wall run and height, the plate rows, and how much of the wall gets sheathing. The interactive calculator on this page recomputes these numbers for your dimensions and adjusts for any US state.
How to measure for framing work
Total the wall runs
Measure each wall along the floor and add the lengths into one number. When a job mixes exterior and interior walls, run the calculator twice: once with sheathing at 100 percent for the outside walls and once at 0 for the partitions.
Match the height to the precut
Wall height here is floor to the top of the top plate. An 8 foot wall takes 92-5/8 inch precut studs, a 9 foot wall 104-5/8, and a 10 foot wall 116-5/8. Taller than that usually means long stock or engineered studs, and it deserves its own takeoff.
Check the opening count
Every window and door gets a king and a jack on each side plus cripples above and below, which the one stud per foot rule covers on an ordinary wall. A wall that is mostly glass, like a sunroom or a garage front, burns more studs and a header per opening, so count those off the plan.
Read the shear wall schedule
Exterior walls get sheathed on every foot, but the structural sheet may call for plywood instead of OSB and a tighter nail spacing on shear walls. Look before you assume OSB everywhere, because the plan wins at inspection.
What this calculator assumes
- Ranges reflect 2026 national averages for 2x4 stud walls at 16 inch centers built on a flat deck or slab.
- Stud prices are for 92-5/8 inch precuts, so the stud line runs low on 9 and 10 foot walls that take longer studs.
- Plates are 2x4 in 16 foot lengths with 10 percent for splices, and sheathing is 7/16 OSB with 10 percent waste, rounded up to whole sheets.
- The 8 percent allowance covers framing nails, sill seal, anchor bolts, straps and hurricane ties.
- Headers, LVL beams, hold-downs, house wrap, permits and crane time come off the plan and are not in the total.
- A single 12 foot non-bearing partition sells for $400 to $1,200 as a job, well above the per-foot math, because the trip and setup are the same size as for a long wall.
Cost factors in framing work
Lumber on bid day
Studs and OSB trade like a commodity, and a package priced in a soft month can lose its margin by delivery. Price from a yard quote dated this week and write into the bid how long the lumber number holds.
2x6 exterior walls
Energy codes push a lot of exterior walls to 2x6 for a deeper insulation cavity. 2x6 at $0.90 to $1.40 a foot runs about two thirds more than 2x4 at $0.54 to $0.85, though 2x6 walls laid out at 24 inch centers trim the layout studs by a third.
Wall height
Each added foot of height means more sheathing and more labor, and walls past 10 feet need staging, longer stock and extra bracing while they stand. Tall walls are where a per-foot framing number quietly goes wrong.
Openings and headers
A doubled 2x10 over a 3 foot window is a few dollars of lumber. A 16 foot garage door header is an engineered beam with its own line, and LVL runs $8.30 to $12.75 a foot. Count headers from the window and door schedule, not by feel.
Shear walls and hardware
In wind and seismic country the plan calls out shear walls with plywood, tighter edge nailing and hold-downs at around $26 each. Those walls frame slower and cost more per foot than the plain walls next to them.
Frequently asked questions
How many studs do I need for a 100 foot wall?
About 100. Layout alone at 16 inch on center is 0.75 studs per foot plus one, or 76 for 100 feet. Corners, wall tees, the kings and jacks at every opening, and blocking push the real count close to one per foot. Grab a few spares, because a crowned or twisted stick that will not sit straight in the wall gets bought twice.
How many sheets of OSB does a wall take?
Wall area divided by 32, since a 4x8 sheet covers 32 square feet, plus 10 percent for cuts at openings and corners. A 100 foot wall at 8 feet tall is 800 square feet, which is 25 sheets on paper and 28 to order. At $20 to $31 a sheet for 7/16 OSB, that is $560 to $868.
What does wall framing cost per linear foot?
At the calculator defaults, an 8 foot exterior wall framed and sheathed lands at $22.70 to $39.31 per linear foot, material and labor together. Set the sheathed share to 0 for an interior partition and the same 100 feet comes to $1,385 to $2,433, about $14 to $24 a foot. Short runs cost more per foot, because setup and cleanup do not shrink with the wall.
Why are plates counted in 16 foot boards?
Long plate stock means fewer splices, and the residential code wants the joints in a doubled top plate offset at least 24 inches. A standard wall carries three rows, one bottom plate and two top, so 100 feet of wall is 300 feet of 2x4, or 21 sixteen foot boards with 10 percent for splices and offcuts. At $8.64 to $13.60 a board that is $181 to $286.
