One of the most common framing questions is: how many studs do I need for a 10-foot wall? The answer depends on your stud spacing and whether the wall has any openings. Use the quick-reference table below, then plug your exact dimensions into the calculator above for a precise count.
| Wall Length | Studs at 16" O.C. | Studs at 24" O.C. | Notes |
|---|---|---|---|
| 8 ft | 7 | 5 | Common for closets and short partition walls |
| 10 ft | 9 | 6 | Standard for bedroom partition walls |
| 12 ft | 10 | 7 | Common living-space wall length |
| 16 ft | 13 | 9 | Garage side wall; matches one sheet of plywood |
| 20 ft | 16 | 11 | Typical garage rear wall |
| 24 ft | 19 | 13 | Two-car garage side wall |
These counts include the two end studs (one at each corner) but do not include extra king studs and jack studs needed around windows and doors. For a 10-foot wall with a standard 36-inch door, for example, you would add 2 king studs and 2 jack studs to the base count—bringing your total to 13 studs at 16" O.C. spacing.
The basic formula for stud count is: (wall length in inches ÷ stud spacing in inches) + 1. For a 10-foot wall (120 inches) at 16" O.C.: (120 ÷ 16) + 1 = 8.5, rounded up to 9 studs. At 24" O.C.: (120 ÷ 24) + 1 = 6 studs.
Always round up to the next whole number—you cannot use a fraction of a stud. When purchasing lumber, add one or two extra studs as backup for defects, splits, and layout adjustments.
