What this estimate includes

This estimate shows wall studs and plate boards for a simple straight wall using the selected stud spacing.

How it’s calculated

Studs = wall length ÷ stud spacing + 1 + extra studs
Plate linear feet = wall length × 3
Plate boards = plate linear feet ÷ board length, rounded up

Before you order

Doors, windows, corners, intersecting walls, blocking, headers, and local framing requirements can change the lumber list. Use this for simple planning only.
