How It Works (Formula & Method)
Studs are the wall length in inches divided by the on-center spacing, plus one, plus extras for corners and each opening. Plate lumber assumes one bottom plate and a double top plate — three times the wall length in linear feet.
Worked Example
Below is a worked example using the calculator's default values. The same numbers are pre-filled in the form above so you can press Calculate and see the result without typing anything.
Inputs used:
- Wall Length (ft): 20
- Stud Spacing (in on-center): 16
