Deck boards
Deck Board Calculator
Use this focused deck-board takeoff when the framing plan is already known. Enter deck dimensions, board face width, gap, stock length, and waste to estimate boards to buy.
How the estimate works
Use the number as a planning starting point.
Deck width divided by effective board width gives the number of board courses. Courses multiplied by deck length gives linear footage; stock-board count uses your selected purchase length.
Check the result
The estimate assumes straight, parallel board courses. Diagonal boards, picture framing, seams, butt-joint layout, board-length availability, and defects can increase material use.

FAQ
Common Deck Board Calculator questions
How many deck boards do I need?
It depends on deck width, board face width, gap, course direction, and available stock length. This tool converts those inputs into a starting count.
Does this include diagonal decking?
No. Add more waste and use a project-specific layout for diagonal or patterned boards.
