Planning notes for Decking Linear Feet Calculator
A 16 x 12 ft deck is 192 sq ft. With 5.5 in boards, raw decking is about 418.9 LF.
Good for
- decking takeoffs
- composite boards
- pressure-treated deck boards
How to use it
- Measure deck length and width.
- Enter the derived square footage.
- Round up to whole board lengths.
Formula check: For decking, use the board face width. Gaps affect layout, but material coverage starts with board width.

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.
