How it Works
1. Calculate Deck Area (sq ft).
2. Formula: (Area * 12) / Board Width.
3. Add 10-15% waste.
What is Deck Board Calculator?
Converts the square footage of a deck into linear footage of decking boards (standard 5.5 inch width).
Step-by-Step Guide
- 1 Area
- Total sq ft.
- 2 Board Width
- Usually 5.5" (nominal 6").
- 3 Calculate
- Total linear feet.
- 4 Waste
- Add for cuts.
Example
Input: 200 sq ft, 5.5" board
Result: 480 Linear Feet (w/ 10% waste)
FAQ
Nominal vs Actual?
A 6-inch board is actually 5.5 inches wide.
Gap spacing?
Use a 16d nail or spacer (1/8 - 1/4 inch).
Joist spacing?
Standard is 16" OC; 12" OC for diagonal decking.
Diagonal waste?
Increase waste to 15-20% for diagonal patterns.
Fasteners?
Plan for ~350 screws per 100 sq ft.
👷 Builder's Tip: Measure twice, cut once. These calculations are theoretical; actual site conditions may affect requirements.
Conclusion
Remember to account for the gap between boards (usually 1/8 to 1/4 inch). While it reduces wood needs slightly, waste from cutting usually offsets this savings.
