Flooring Waste Percentage by Pattern: Straight vs. Diagonal vs. Herringbone

How much extra flooring to buy for straight, diagonal, and herringbone layouts, and why more complex patterns waste more material to angled cuts.

Purchase quantity = measured area + waste buffer, rounded up to full packagesMeasured areaDashed outer edge = waste buffer (pattern cuts, mistakes, future repairs)+ waste %
How the Room / Project Material Estimator works

The layout pattern you choose for a flooring installation directly changes how much extra material you need to buy — not because the room gets any bigger, but because more complex patterns create more angled cuts, and every cut wastes a piece of plank or tile that can't be reused.

PatternTypical wasteWhy
Straight10%Cuts run parallel to the walls — minimal angled waste
Diagonal15%45° cuts along every edge of the room
Herringbone20%+Every piece is cut at an angle, with a repeating zigzag pattern

Why this matters for your order

Ordering with straight-layout waste assumptions for a herringbone installation is one of the most common reasons a flooring job runs short mid-project — the visual complexity of the pattern doesn't just affect installation time, it directly increases the quantity of material consumed.

Pick your pattern in the Room / Project Material Estimator and the waste percentage adjusts automatically — or override it manually if your installer quotes a different number.
