The total length of the wall run.
Measure the full horizontal run of the wall along the floor.
The on-center spacing between studs, per your framing plan.
16 in (405 mm) o.c. is the most common spacing; 24 in (610 mm) o.c. is used where the stud size, gauge, and loading allow it.
Studs needed
26 studs
- Whole bays at the plan's centres

How this was calculated
Formula source(s)
- CFS stud count = ceil(wall length ÷ spacing) + 1 — the standard layout method, counting both end studs plus intermediate studs at 16 in or 24 in o.c. per SSMA/IBC/ASCE, identical in method to wood stud framing
Inputs used
- Wall Length
- 33 ft
- Stud Spacing (o.c.)
- 16 in
Intermediate steps
- Whole bays at the plan's centres
- 24
- Closing bay at the end of the run
- 12 in
What this calculation does not cover
- A stud count is not a stud specification. Non-structural drywall studs and structural studs share the same depths and the same spacings and are rolled from quite different steel thicknesses, and the two are not interchangeable at any spacing — a schedule that says how many says nothing about the mil thickness the wall's height and loading actually require.
- Bridging is a function of height and cannot appear in a count made from length. A cold-formed C-section twists under load, so rows of bridging or strapping up the wall are what hold the studs straight, and their number comes from how tall the wall is — none of it scales with the run measured along the floor.
