Як користуватися Decking Calculator — calculate decking boards and waste
Plan board quantity from deck dimensions, board width, gaps, stock lengths and cutting allowance before preparing a final layout.
Boards across the deck are based on board width plus gap. Linear requirement then depends on the board direction and available stock lengths.
Plan board quantity from deck dimensions, board width, gaps, stock lengths and cutting allowance before preparing a final layout. The linked Sellible tool keeps the fields, units and output together so the assumptions can be reviewed before the result is used.
- 1
Choose the board direction before measuring runs.
- 2
Enter actual board face width and designed gap.
- 3
Apply waste after considering stock lengths and joins.
Example values and result
These values demonstrate the method; replace them with measurements, rates or file details that match the real task.
- Deck
- 5 m × 3 m
- Board face
- 140 mm
- Gap
- 5 mm
- Waste allowance
- 10%
The board count changes when the board direction changes. The calculator supports quantity planning; a cutting layout should also consider joins, stagger and support positions.
Точність і практичні поради
- Confirm joist spacing and manufacturer fixing guidance.
- Plan breaker boards, picture frames and stair details separately.
- Check expansion gaps and board-batch availability.
Common mistakes
- Using nominal rather than actual board width.
- Ignoring the gap between boards.
- Assuming total linear metres guarantees a workable cutting layout.
