How tile layout pattern drives waste — straight ≈7%, diagonal & herringbone ≈15%
The layout pattern — not just the square footage — sets your waste factor: straight ≈7%, running bond ≈10%, diagonal 45° ≈15%, herringbone ≈15%+. Angled patterns throw away a cut at every wall.
What this diagram shows
Four small tile fields show the same area laid four ways and the extra tile each pattern wastes in cuts. A straight grid wastes about 7 percent because cut-offs from one wall start the next row. A one-third running bond wastes about 10 percent. A 45-degree diagonal layout wastes about 15 percent because a triangular off-cut is thrown away at every wall. A herringbone wastes about 15 percent or more because each plank needs two angled cuts. Waste rises further for DIY installs, natural stone, and large-format tile.
