Planning notes for Shiplap Linear Feet Calculator
120 sq ft of wall with 5.25 in exposed shiplap needs about 274.3 LF before waste.
Good for
- accent walls
- interior shiplap
- tongue-and-groove style layouts
How to use it
- Measure wall area.
- Use the exposed reveal, not the full board width.
- Add waste for end cuts and matching boards.
Formula check: Shiplap LF uses exposed width because overlap reduces coverage.

100 LF
Frequently Asked Questions
A linear foot is one foot of length. It does not include width or thickness unless you are converting from area or board feet.
Pro Tip
A waste factor of 5-15% helps cover cuts, mistakes, and layout adjustments. When in doubt, round up.
