ABOUT THIS TOOL

When to use a lumber calculator

Estimate stud count and lumber linear footage for a straight framed wall.

All assumptions are visible and adjustable. Check rates and underlying data against original sources before making a decision.

HOW IT WORKS

The calculation

Estimated studs = ceil(wall length × 12/stud spacing) + 1; total linear lumber feet = studs × stud length + plates × wall length.
