Why Waste Allowance Matters
Flooring is sold in fixed-size boxes. Every cut creates an offcut, and not all offcuts are usable. Ordering too little means a second delivery and potential colour batch mismatch. Ordering too much wastes money — though most retailers accept returns on unopened boxes.
Waste by Layout Type
- 10% — straight rectangular room, boards parallel to walls (default)
- 12% — rooms with bay windows or small alcoves
- 15% — L-shaped rooms, diagonal installation
- 20% — herringbone or chevron patterns, complex room shapes
Formula: Order Quantity = Room Area × (1 + Waste%)
💡 Always buy one extra box beyond your calculated amount. Store it for future repairs — dye lots change over time and replacement packs may not match exactly.
Calculating Box Count
Once you have total order quantity with waste: Boxes = ⌈(Area × (1 + Waste%)) ÷ Box Coverage⌉
Common box coverages: Laminate/LVP/Engineered ~20 sq ft · Tile ~10 sq ft. Check the pack label for exact coverage — it varies by manufacturer.
Practical Tips
- Use the Flooring Calculator — it rounds up to the nearest whole box automatically
- Diagonal installation always needs at least 15% — the angled cuts waste significantly more at wall edges
- Stagger joints by at least 1/3 of a plank length for structural integrity and visual appeal
- Keep all packaging until the project is completely finished — some suppliers won't accept returns without original packaging
FAQ
Most retailers accept returns of unopened boxes within 30–90 days. Some charge a 10–15% restocking fee. Always keep at least one box for repairs regardless of return policy.
Order immediately from the same supplier and request the same batch number printed on your original boxes. Even then, dye lot variation can cause subtle colour differences — this is why ordering extra upfront is always the right call.
