Deck board count and linear footage for a deck field.
Deck dimensions, board width, gap, stock length, borders and waste.
Rows, linear footage and a board purchase starting point.
Picture framing, stairs, diagonal layouts, joists, fasteners and damaged boards need separate quantities.
Estimate deck-board rows, linear footage and purchase allowance from deck dimensions, board width and gap.
Estimate deck-board rows, linear footage and purchase allowance from deck dimensions, board width and gap. Use the working RenoMetric calculator below for the actual estimate, then use this page to check assumptions, package rounding and project-specific considerations.
Use your measurements to see the estimated project quantity.
Add waste and round to complete bags, boxes, cans, bundles or delivery quantities.
Review product coverage, site conditions, local requirements and supplier details before ordering.
Use the calculator result as a planning quantity, then verify the final order with the product label or supplier quote.

For a 12 ft wide deck, the number of board rows depends on the installed face width plus the planned gap between boards.
Measure the actual project rather than relying on listing dimensions. For irregular spaces, split the surface into simple measurable sections and add the results. Use the exact product label for package coverage, yield, density or square-foot coverage whenever it is available.
Keep waste and package rounding as separate steps. Waste covers cuts, breakage, pattern matching and unavoidable offcuts. Package rounding reflects the fact that many materials are sold only in complete bags, boxes, bundles or cans.
Before you buy: this page is a planning guide, not a contractor quotation or structural design. Verify final quantities with the product manufacturer, supplier or installer when project conditions could materially change the result.
Use the actual installed face width, not the nominal lumber name.
The repeated gap contributes to total deck width and affects the number of board rows.
Not automatically. Borders and breaker boards should be added as separate measured components.
