Deck Board Calculator

Estimate decking boards for your deck — rows across the joists, linear feet, and full boards — with the board gap, pattern waste, fasteners, U.S. pricing, a material comparison, and a downloadable PDF.

Board coverage assumes boards run the deck length across the joists. Prices use 2024-2025 U.S. figures and vary by region and grade. For planning purposes only.
