Board face, gap, direction and stock length all change the count. Set them here and see how each one moves the order.
How it works
Each board covers its face plus the gap. Rows × run gives linear feet, with 10% extra, or 15% for diagonal layouts.
Before you order
- Check the actual width of your decking, since nominal 6 inch boards measure about 5.5 inches.
- Wet pressure-treated boards shrink, so many builders butt them tight and let the gap form.
- Diagonal boards need tighter joist spacing on some decking. Check the product rating.
Common questions
What gap should deck boards have?
Around 1/8 inch for dried boards. Composite decking has its own required spacing.
How much extra should I order?
About 10 percent for straight layouts and 15 percent or more for diagonal or framed patterns.
