How many studs for a 16-foot wall?
Quick Answer
A 16-foot wall framed with studs on 16-inch centers needs 13 studs plus 3 plates (top plate, double top plate, and bottom plate) — 16 total pieces of lumber. On 24-inch centers, the same wall needs 9 studs. Add 1 extra stud for every door or window opening (king stud, jack stud, cripple arrangement).
Quick Reference Table
| Wall Length | Studs (16" OC) + plates |
|---|---|
| 8 ft | 7 studs + 3 plates |
| 10 ft | 9 studs + 3 plates |
| 12 ft | 11 studs + 3 plates |
| 16 ft | 13 studs + 3 plates |
| 20 ft | 16 studs + 3 plates |
| 24 ft | 19 studs + 3 plates |
How to Calculate It Yourself
- 1
Divide wall length by stud spacing: 16 ft ÷ 1.333 ft (16") = 12 spaces.
- 2
Add 1 for the end stud: 12 + 1 = 13 studs.
- 3
Add plates: 3 plates (bottom plate + top plate + double top plate), each the full 16 ft = 3 more pieces.
- 4
Add extras for openings: each door or window needs 2 king studs + 2 jack studs + cripples. Rough estimate: add 5 studs per opening.
Pro Tip
The industry shortcut: multiply wall length in feet by 0.75 to get stud count at 16" OC, then add 1 for the end. For a 16-foot wall: 16 × 0.75 + 1 = 13 studs. Add 10% for waste and corners.
