1) Units & Layout
Pattern factor accounts for extra offcuts and layout complexity.
2) Areas (Segments)
| # | Length | Width | Area | |
|---|---|---|---|---|
| Total areas | 0.000 | |||
Use multiple segments for L-shaped spaces or adjoining rooms.
3) Exclusions (Openings/Obstructions)
| # | Length | Width | Area | |
|---|---|---|---|---|
| Total exclusions | 0.000 | |||
4) Board, Packaging & Brand Presets
Presets are generic examples. Verify with current datasheets before ordering.
If using boxes, we round up to full boxes.
5) Box-size Optimizer
Provide up to four box sizes with coverage and optional price. The optimizer finds a mix meeting your required area with your chosen objective.
| # | Label | Coverage | Price (optional) |
|---|
Optimizer results
objective: leftover| Size label | Coverage | Price | Count | Subtotal coverage | Subtotal cost |
|---|---|---|---|---|---|
| Totals | 0 | 0 | 0 | Leftover: 0 | |
These are planning estimates; confirm against brand packaging and yields.
All calculations are approximations; verify against manufacturer data.

Example scenarios
| Rooms | Plank (W×L) | Pattern | Waste | Boxes? | |
|---|---|---|---|---|---|
| 5.0×4.0 m | 180×1200 mm | Straight | 10% | 2.376 m²/box | Load |
| 16×12 ft | 5×48 in | Herringbone | 12% | None | Load |
| 3.2×2.8 m + opening 1.0×0.6 m | 150×2200 mm | Chevron | 8% | 2.0 m²/box | Load |
Formulas used
- TotalArea = Σ(Length × Width) − Σ(OpeningLength × OpeningWidth).
- PatternAdjusted = TotalArea × PatternFactor.
- WithWaste = PatternAdjusted × (1 + Waste% / 100).
- BoardArea:
- Metric: (BoardWidth_mm ÷ 1000) × (BoardLength_mm ÷ 1000) = m²
- Imperial: (BoardWidth_in ÷ 12) × (BoardLength_in ÷ 12) = ft²
- BoardsRequired = ceil(WithWaste ÷ BoardArea).
- If using boxes: BoxesRequired = ceil(WithWaste ÷ BoxCoverage); Leftover = BoxesRequired × BoxCoverage − WithWaste.
How to use this calculator
- Select your preferred measurement system.
- Add one or more room segments with their lengths and widths.
- Add any openings or obstructions to subtract from the area.
- Enter plank face width and length, set waste, choose pattern.
- Optionally enable boxes and enter coverage per box from datasheets.
- Choose a preset or run the optimizer for a best-fit box mix.
- Click Calculate, then export your results to CSV or PDF.
FAQs
Typical ranges are 7–12% for straight layouts, increasing to 10–15% for herringbone, chevron, or diagonal layouts. Tight rooms with many cuts may require more.
Use the exposed face width and nominal length you intend to lay. If the product lists coverage per box, enable boxes and enter that value directly.
No. Pattern factor models extra layout complexity. Add a separate waste percentage to cover offcuts, defects, and selection loss.
Yes. Add each room as a separate area segment. Add openings or islands as exclusions to subtract their area from the total.
Choose a preset to auto-fill board size and coverage values. Presets are generic examples; always confirm current packaging and board dimensions before placing orders.
