How to use the Lumber Calculator

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

Calculation formula

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

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations

Preliminary straight-wall material plan; corners, openings, headers, bracing and waste are excluded.
