How to Calculate Tiles Needed

Calculating the number of tiles for your project involves measuring your space, determining tile coverage, and adding extra for waste and cuts.

Step-by-Step Calculation

1. Measure the length and width of your area
2. Calculate total square footage (length x width)
3. Determine tile coverage per tile (tile length x tile width)
4. Divide area by tile coverage
5. Add 10-15% for waste and cuts

Common Tile Sizes

Size (inches)	Coverage per Tile	Common Use
4" x 4"	0.11 sq ft	Accent tiles, backsplash
6" x 6"	0.25 sq ft	Backsplash, small areas
12" x 12"	1 sq ft	Floors, walls
12" x 24"	2 sq ft	Modern floors
18" x 18"	2.25 sq ft	Large floors
24" x 24"	4 sq ft	Large open spaces

Why Add Extra for Waste?

• Cuts and breakage: Tiles at edges need cutting, some may break
• Pattern matching: Diagonal or complex patterns need more tiles
• Future repairs: Keep extra tiles for replacing damaged ones
• Color variations: Tiles from different batches may vary slightly

Recommended Waste Percentages

• Straight lay: 10% extra
• Diagonal lay: 15% extra
• Complex patterns: 15-20% extra
• Large tiles in small rooms: 15% extra

Tips for Tiling Projects

• Always buy all tiles at once from the same lot/batch
• Dry-lay tiles before installing to check pattern
• Start from center of room for balanced cuts at edges
• Use appropriate grout width for tile size
• Store extra tiles flat in a dry place for future repairs
