Calculate tiles needed for various layout patterns with waste by pattern type.
A tile pattern calculator estimates the number of tiles needed for various layout patterns, accounting for grout width and pattern-specific waste factors.
| Pattern | Waste % |
|---|---|
| Straight (Grid) | 5–10% |
| Brick / Offset | 10% |
| Diagonal (45°) | 15% |
| Herringbone | 15–20% |
| Chevron | 15–20% |
| Basketweave | 10–15% |
Formula
Tiles = (Room Area ÷ Tile Area) × (1 + Pattern Waste %)Room Area = length × width in square feet
Tile Area = (tile length + grout) × (tile width + grout) in square feet
Pattern Waste % = 5–20% depending on layout pattern
Worked Example
12 × 10 ft room, 12×12 tiles, straight pattern
Did you know? Herringbone patterns have been used since Roman times in road construction and became popular in interior design during the 16th century (source: Tile Council of North America).
