Formula
Worked example
For 100 ft of wall with two top plates, one bottom plate, and 10% waste, plan for 330 linear feet of plate lumber.
What to keep in mind
- Openings do not always reduce plate requirements, so this calculator uses total wall length.
- Splices, corners, laps, treated bottom plates, and local code requirements can affect ordering.
