How many studs for a 24-foot wall?
Quick Answer
A 24-foot wall at 16-inch on-center spacing needs 19 studs plus 3 plates (72 linear feet of plate stock). At 24-inch spacing: 13 studs. A 24-foot wall is a common garage wall dimension — plan for a 9-foot garage door opening, which requires 2 king studs, 2 jack studs, a LVL header, and multiple cripple studs above.
Quick Reference Table
| Spacing | Studs for 24-foot wall |
|---|---|
| 16" OC | 19 studs + 3 plates |
| 24" OC | 13 studs + 3 plates |
| Add 9-ft garage door | +6 studs + header |
| Add standard door | +5 studs |
| Add window | +4 studs |
How to Calculate It Yourself
- 1
Divide by spacing: 24 ft = 288 inches. 288 ÷ 16 = 18 spaces + 1 end = 19 studs.
- 2
Plates: 3 plates × 24 ft = 72 linear feet. Buy 12 × 8-ft 2×4s or 8 × 10-ft boards.
- 3
For a garage door: rough opening is 9 ft wide × 7 ft tall. Add double king studs, jack studs, and a point-loaded LVL header. Consult an engineer for header sizing.
- 4
Total studs including garage door: 19 + 6 = 25 studs plus header material.
Pro Tip
A 24-foot garage wall with a 9-foot door leaves 15 feet of framed wall. That 15-foot section needs a properly sized header — typically a 4×10 or LVL beam to carry roof loads. Don't size the header by guessing — use a span table or have an engineer specify it.
