Input and output guide
What each value means
The labels and units below are part of this calculator’s visible methodology. Replace every default with measurements or product data from the actual project.
Total wall length

Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Field studs ≈ total wall length ÷ spacing + one end stud per wall run. Add modeled corner and opening studs, then apply waste and round up.

FAQ
Drywall Stud Count Calculator questions
Why add wall runs?+
Each separate run has end conditions that are not captured by total length alone.
How many studs should be added for an opening?+
That depends on king studs, jack studs, sill framing and header design; use the approved framing detail.
Does this size headers?+
No. Header design and load paths require project-specific structural information.
