How It's Calculated

• Number of boards: (Deck Width / (Board Width + Gap)) rounded up, then multiplied by (Deck Length / Board Length) rounded up.
• Number of joists: (Deck Length * 12 / Joist Spacing) + 1, rounded down.
• Fasteners: 2 fasteners per joist per board intersection.
• Square footage: Deck Length × Deck Width.
