## How to Calculate Deck Boards
### Formula
**Boards Across = Deck Width / (Board Width + Gap)**
**Total Boards = Boards Across × Deck Length / Board Length × (1 + Waste)**
A nominal 2×6 deck board is actually 5.5 inches wide. Include a 1/8-inch gap between boards for drainage and expansion. Board lengths come in 8, 10, 12, 14, 16, and 20 ft.

计算示例
A 16 ft by 12 ft deck with 5.5-inch (2×6) boards, 1/8-inch gaps, 16 ft board length, 10% waste.
- Board coverage width = (5.5 + 0.125) / 12 = 0.469 ft
- Boards across = 12 / 0.469 = 25.6 → 26 boards
- Linear feet = 26 × 16 = 416 lin ft
- Boards at 16 ft = 416 / 16 = 26 boards
- With 10% waste = 26 × 1.10 = 28.6 → 29 boards
