Deck Material Calculator
Calculate how much material you need for your deck project with our comprehensive calculator. Determine boards, fasteners, joists, and total costs for your deck construction.
Step 1: Deck Dimensions
Standard Deck Sizes
Most decks use 2×6 boards (5.5″ wide) with a ¼” gap between boards for drainage. Board length is typically 12, 16, or 20 feet.
Step 2: Material and Cost
About Waste Factor
The waste factor accounts for cutting waste, damaged boards, and material that doesn’t meet quality standards. 10% is typical for most deck projects.

Deck Material Formula
Boards Needed = (Deck Width × 12) / (Board Width + Gap) × Waste Factor
To calculate materials: Convert deck width to inches, divide by board width plus gap, then multiply by waste factor. Multiply by deck length for linear feet needed.
