TryBuildCalc10 Ft Wall Stud Calculator (116-5/8" Precut Studs)
Size studs for a 10 ft wall.
🕒 Last updated: September 2, 2026
Inputs
ℹ️The total run of this wall — calculate one wall (or one continuous straight run) at a time.
ℹ️Determines the precut stud length used (accounts for the double top plate and single bottom plate).
ℹ️Standard 3-stud corners/intersections are the traditional approach; advanced/energy-efficient 2-stud framing uses drywall clips or ladder blocking instead, saving lumber and improving insulation.
ℹ️Sets the wall thickness used to label studs, plates, and header spacer notes — doesn't change piece counts, which depend only on length and spacing.
ℹ️Number of outside corners this wall run forms with an adjoining wall.
ℹ️Number of interior partition walls that intersect (T into) this wall.
Header Sizing (for Openings Below)
ℹ️Measured perpendicular to the roof ridge. If your actual width falls between two options, pick the next-larger one for a conservative (safer) header size.
ℹ️How much load this wall's header(s) carry. Assumes 30 psf ground snow load, #2-grade lumber, and center-bearing floor framing where a floor is selected — see the Table tab for the full reference and its stated assumptions.
Door & Window Openings
Waste & Lumber
ℹ️Accounts for cut-offs, damaged pieces, and layout adjustments — 10% is a common estimating default.
ℹ️Standard stock length used to buy top/bottom plate lumber — affects how many boards are needed after joints.

Corner studs: 6 (2 corners × 3)
King studs: 2
Jack (trimmer) studs: 2
Cripple studs: 4

Openings
1× Door (36" wide): 2 king + 2 jack + 4 cripple = 8 studs — header: 2× 2x4
Assumptions Used
Standard US residential light-frame wall construction. Total Framing Studs is a conservative piece count — every king, jack, and cripple stud is counted as one full-length precut piece to buy and cut down, since cripples and trimmed jacks are commonly cut from the same precut stock rather than purchased as a separate shorter product. Header size and jack-stud count are looked up from the 2012 IRC Table R502.5(1) (Girder and Header Spans for Exterior Bearing Walls) by opening width, your selected Building Width, and Floors Above Header — assuming a 30 psf ground snow load, #2-grade Douglas Fir-Larch/Hem-Fir/Southern Pine/Spruce-Pine-Fir lumber, and center-bearing floor framing where a floor is selected. This is 2012-edition data specifically — later IRC editions (including 2024) have revised header-span provisions, so it is not guaranteed to match your locally adopted code's current table. A higher snow load, different species/grade, clear-span floor framing, a newer code edition, or any load-bearing opening must be verified against the exact adopted code and a structural professional — this is a reference estimate, not a structural design. Corner and intersection stud counts follow the selected framing style (3-stud standard vs. 2-stud advanced/energy-efficient). Cripple stud count is based on the opening's width at the field spacing, not its height. This is a reference estimate — confirm against local code requirements and a licensed contractor or framer before final installation.

10 ft wall stud count and precut length
10 ft ceilings are common in great rooms, foyers, and higher-end residential and light-commercial construction — a 10 ft wall uses a longer 116-5/8" precut stud, different from standard 8 ft or 9 ft walls.
This page defaults to a 10 ft wall height — edit the inputs above to match your actual wall length, corners, and openings.
- 10 ft walls use 116-5/8" precut studs, the longest of the three standard precut lengths.
- Taller walls are more likely to need engineered lumber, additional blocking, or wind/seismic bracing depending on local conditions — confirm separately from this calculator.
- Standard precut studs may not be stocked as commonly at 10 ft length as 8 ft — confirm lead time and availability with your lumber supplier.
Stud Calculator Formula: How Is It Determined?
Four categories of studs, summed, then a waste factor and plate lumber calculated separately.
Step 1 — Field Studs
Field Studs = ceil((Wall Length in inches) ÷ Spacing) + 1
The +1 accounts for both end studs — dividing alone only counts the studs in between.
Step 2 — Corner & Intersection Studs
Corner Studs = Corners × (3 standard | 2 advanced)
Intersection Studs = Intersections × (3 standard | 2 advanced)
The traditional 3-stud corner gives solid drywall backing on both sides but creates an insulation dead zone; advanced/energy-efficient 2-stud framing uses drywall clips instead, saving lumber and improving wall insulation.
Step 3 — Opening Studs, Header Size & Jack Studs (per door/window)
King Studs = 2 (always, one per side)
Header Size + Jack Studs (NJ) = looked up from the 2012 IRC Table R502.5(1) header-span table by Opening Width, Building Width & Floors Above
Jack Studs = 2 × NJ (NJ = jack studs required per end, from the table)
Cripples Above Header = ceil((Opening Width - 2) ÷ Spacing) + 1
Cripples Below Sill = same formula, WINDOWS ONLY
Cripple stud count is driven by the opening's WIDTH at the field spacing — not by wall or header height, which only affects each cripple's individual cut length, not how many are needed. Header size and jack-stud count are looked up from the 2012 IRC prescriptive header-span table (see the Table tab), not a flat width cutoff — the table assumes 30 psf ground snow load, #2-grade Douglas Fir-Larch/Hem-Fir/Southern Pine/Spruce-Pine-Fir lumber, and center-bearing floor framing where a floor is selected. This is still a reference estimate for a material takeoff, not a structural design — later IRC editions (including 2024) have revised header-span provisions, so verify against your locally adopted code EDITION and its exact table (not just your ground snow load and floor framing type), and have a structural professional confirm any load-bearing opening.
Step 4 — Waste Factor & Plates
Total Studs = ceil((Field + Corner + Intersection + Opening Studs) × (1 + Waste % ÷ 100))
Plate Boards = ceil((Wall Length × 3) ÷ Plate Board Length)
Plates use 3× the wall length (a double top plate plus a single bottom/sole plate), converted into a board count at the selected stock lumber length.
Worked Example
This example walks through your current inputs above, using the same steps as the Formula section.
Input Values Used
| Input | Value | Why it is used |
|---|---|---|
| Wall length / height | 12 ft / 10 ft | Sets field stud count and precut stud length (116.625") |
| Framing style | Standard (3-stud) | Sets corner/intersection stud count each |
| Building width / floors above | 28 ft / Roof + ceiling only (no floor above) | Sets header size and jack-stud count (NJ) for each opening below |
Step 1 & 2 — Field, Corner & Intersection Studs
| Calculation | Result |
|---|---|
| Field studs | 10 |
| Corner + intersection studs | 6 |
Step 3 — Opening Studs
| Calculation | Result |
|---|---|
| 1× door @ 36": 2 king + 2 jack + 4 cripple (header: 2× 2x4) | 8 |
| Opening studs subtotal | 8 |
Step 4 — Waste Factor & Plates
| Calculation | Result |
|---|---|
| Subtotal studs (before waste) | 24 |
| Total studs (with 10% waste) | 27 |
| Plate boards (8 ft, 36 ft total) | 5 |
Therefore, this 12 ft wall needs approximately 27 studs (116.625" precut) and 5 plate boards.
