Flooring Waste Factor: How Much Extra Material to Order
Add a waste factor to every flooring order: 5–8% for straight-lay LVP and laminate, ~10% for hardwood, 10–15% for tile, and 15–20% for diagonal or herringbone patterns. Then round up to full boxes. On a 1,000 sq ft straight LVP job at 8%, you order 1,080 sq ft. Under-order and a mid-job reorder costs you days, a possible dye-lot mismatch, and your margin.
Waste factor is the cheapest insurance on a flooring job, and the most common place new installers lose money. Order too little and you stop the job to reorder — eating labor, risking a dye-lot color shift, and looking unprofessional. Order way too much and you’ve bought material you can’t bill. The right percentage, applied every time, fixes both.
Waste factor by material and layout
| Flooring / layout | Waste factor |
|---|---|
| LVP / laminate, straight lay | 5–8% |
| Hardwood, straight lay | 8–10% |
| Tile, straight lay | 10% |
| Diagonal layout (any) | +5% on top |
| Herringbone / chevron / patterns | 15–20% |
| Lots of cuts, angles, small rooms | add 2–5% |
Layout matters as much as material: the same LVP at straight-lay needs 8%, but run it diagonally and you’re closer to 12–13% because every edge cut creates an offcut you can’t always reuse.
A real example
A 1,000 sq ft LVP living/dining space, straight lay:
- Base area: 1,000 sq ft
- 8% waste → 1,080 sq ft to order
- Plank box covers ~20 sq ft → 54 boxes → round up to 55 boxes (1,100 sq ft)
That box-rounding step is the one people skip. You don’t buy 1,080 sq ft — you buy whole boxes, so you always round up to the next full box. The leftover also becomes the homeowner’s attic spare for future repairs, which is a nice professional touch to mention.
Why under-ordering is the expensive mistake
Running short isn’t just “order more.” It’s: stop the crew, lose a half-day or more of production, pay a second delivery or pickup, and risk the reorder coming from a different dye lot with a visible color/shade variation across the floor. On a job with $2,100 of labor in it, a one-day stall can cost more than the entire waste-factor overage would have. Always err on the full-box side.

Frequently asked questions
What is a good waste factor for LVP?
5–8% for straight lay; add ~5% for diagonal. Round up to full boxes after applying it.
Why is herringbone waste so high?
Angled, interlocking patterns create more unusable offcuts at every edge and direction change — 15–20% is realistic.
Do I round to square feet or boxes?
Boxes. Flooring sells by the box, so always round up to the next full box above your waste-adjusted square footage.
What about dye lots?
Order all the material for a job at once from the same dye lot. A reorder can arrive a shade off and show across the floor.
