- Joist spacing: 16 inches
Calculator Output:
- Decking boards: 32
- Joists: 10
- Beams: 3
- Posts: 6
- Screws: 200
This provides a full material list for a medium-sized deck, ensuring precise planning.
Example 2: Small Deck
- Deck size: 10 ft × 8 ft
- Board width: 5.5 inches
- Board length: 10 ft
- Joist spacing: 16 inches
Calculator Output:
- Decking boards: 18
- Joists: 6
- Beams: 2
- Posts: 4
- Screws: 120
Perfect for a small patio or balcony deck.
Understanding Decking Material Calculations
Decking material calculations consider:
- Deck area – Length × Width of the deck
- Board coverage – Width × Length of each board, including spacing
- Joist spacing – Determines the number of joists required
- Beam and post placement – Supports structural integrity
- Fasteners – Screws or nails needed for boards, beams, and posts
Including a 5–10% waste allowance is recommended for cutting errors or mistakes.
Benefits of Using a Decking Material Calculator
