Stud Count
Free Stud Count calculator with clear step-by-step results.
About Stud Count
Common studs are wall length over spacing plus one for the end, but openings and junctions add a great deal: each opening needs two trimmers and two cripples, and each corner or T-junction needs a pair. The linear timber figure converts stud count into what you actually order.
Formulas
Common studs
Studs = ceil(wall length / spacing) + 1
Total studs
Total = common studs + openings x 4 + junctions x 2
Worked example
With the default values below, Stud Count returns Studs required of 28. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- Load-bearing wall framing, lintel sizing over openings and bracing requirements are governed by building codes. Structural walls should be designed or checked by a qualified professional.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions
Should I use 400 or 600 mm spacing?
Four hundred is standard for load-bearing walls and gives a stiffer surface for plasterboard. Six hundred is common for non-load-bearing partitions and saves timber, but needs thicker board.
Are noggings necessary?
They stiffen the wall, provide fixing for board edges, and are needed where heavy items will be hung. One row at mid-height is typical for a 2.4 m wall.
