Deck Calculator

What is the Deck Calculator – deck boards and framing material?

The Deck Calculator calculates the amount of boards needed for building a deck, the framing structures, and estimates the material costs. The calculator takes into account installation gaps and waste percentage.

The calculator is free, works in the browser, and does not require registration. The site offers over 200 calculators with 2026 data.

Calculation Principle

Boards = Deck area ÷ (board width + installation gap). Run = Boards × Length.

Fill in your information in the fields and press the calculate button – the result will appear immediately.

Practical Example

Deck 4 × 6 m = 24 m², board 28 mm + 5 mm gap = 33 mm → 24 ÷ (0.028 × 6) = 143 boards. Reserve 10 % → buy 160 pieces.

Tips

• Leave a 0.2–0.31 in installation gap between the boards – this allows for wood movement.
• Oil the wood before and after installation for sharp-edged wood types.
• Deck screws (TORX) are better than nails – removable if necessary.
