The total length of wall to be framed.
This is the field stud count only. Corners, T-intersections, openings, kings, jacks and cripples all add studs that spacing alone does not predict.
Field studs (before extras)
31 studs
One stud per 16 in of run, plus one to close the end: length in feet × 0.75, rounded up, plus one. Field studs only — add corners, T-intersections, kings, jacks and cripples separately.
- Studs at 16 in centres, before the closing stud
- 30 studs

How this was calculated
Formula source(s)
- 16 in on centre spacing gives 0.75 studs per linear foot of wall
- 24 in on centre gives 0.5 studs per linear foot; advanced framing uses this where the structure permits
Inputs used
- Wall length (ft)
- 40
Intermediate steps
- Studs at 16 in centres, before the closing stud
- 30 studs
Confidence note: One stud per 16 in of run, plus one to close the end: length in feet × 0.75, rounded up, plus one. Field studs only — add corners, T-intersections, kings, jacks and cripples separately.
What this calculation does not cover
- 0.75 studs per linear foot is the spacing alone. It does not add the extra stud every run needs at its end, nor the doubled studs at corners and T-junctions — on a partition layout with several returns, that is a real number of sticks.
- Openings are not in it. A door or window needs a pair of trimmers, a pair of kings and cripples above and below, all of which sit outside the 16 in rhythm and none of which this counts.
- Nothing here is a plate. A stud count is not a timber order: top and bottom plates, a second top plate where one is required, and noggings or blocking are all separate lengths.
- 24 in centres give 0.5 studs per linear foot and are permitted for many non-load-bearing and some load-bearing walls. Converting a 24 in layout at this factor buys half as many studs again as the wall needs.

Framing take-off starts with spacing and length, and this produces the field stud count that follows from them. Sixteen inch centres yield three studs for every four feet of wall, plus one to close the run. What it deliberately does not include is everything that makes a real wall: corner assemblies need extra studs both for bracing and to give the boarder something to fix to, and every door and window brings kings, jacks, cripples and a header. On a wall with several openings those extras can rival the field count, so this figure is a starting point rather than a materials list. The sixteen-inch module persists mainly because it divides into the forty-eight inch sheet width.
