Wood & boards
Decking Calculator
Your measurements : length, width, board width. Your estimate : pieces to buy, rows, length.
How the calculation works
Decking Calculator
round up(Rows × round up(Length / Length per piece) × (1 + Waste allowance / 100))Before you order
- Use the coverage, yield and dimensions printed on your product. Waste allowance is adjustable; real cuts and site conditions may change the order.
- Quantity estimate, not an optimized cutting plan. Add an allowance for the layout, joints and unusable offcuts.
- Planning estimate only. This is not a structural design, a safety approval or a local code check.
