Your estimate
Enter your measurements and select Calculate to see your estimate.
Estimate coverage by deck area divided by the face area of a board, then apply waste. This assumes boards can be cut and used efficiently.
A 12 × 10 ft deck with 6 in × 12 ft boards needs about 20 boards before waste or 22 at 10%.
No. This covers surface boards only; plan framing and structural details separately.
