How the Deck Build Calculator Works

This calculator focuses on the essential measurements required to estimate deck materials accurately.

Required Inputs:

• Deck Length (feet)
• Deck Width (feet)
• Board Width (inches)
• Board Spacing (inches)

Outputs You Get:

• Total Deck Area (square feet)
• Number of Deck Boards Required
• Estimated Linear Feet of Material

Calculation Logic:

1. Deck Area
   Deck Area = Length × Width
2. Board Coverage Width
   Coverage = Board Width + Spacing
3. Number of Boards
   Boards Required = Deck Width ÷ Coverage
4. Total Linear Feet
   Boards × Deck Length
