How it works
Divide the wall length by the spacing to get the number of gaps. Round up, then add one, because a wall has one more stud than it has gaps.
Spacing is measured from the center of one stud to the center of the next. 16 inches and 24 inches are the two common choices.
Worked example
A wall 12 ft long at 16 in on center needs 10 studs, with 9 spaces between them.
Questions
Where do I start marking?
Mark the first stud at the end of the plate, then measure each spacing from the center of the one before. Check the last mark against the far end of the wall.
Do corners and openings change the count?
Yes. Add studs for corners, and for door and window openings, which need extra framing. This counts only the plain run of wall.
Why round up?
A partial gap still needs a stud at the end. Rounding up keeps the spacing at or under your target.
