📐 Formula
Tiles Needed = Area ÷ (Tile Area + Grout Area) × (1 + Waste%)💡 How It Works
- •Tile installation requires extra tiles for cutting waste and breakage.
- •Standard rectangular spaces need 10% extra; diagonal patterns or complex layouts need 15% or more.
- •Typical grout width is 2-3mm for standard tiles, 3-5mm for large format tiles.
- •Tiles are sold by the box, so you'll need to round up to complete boxes.
- •Smaller tiles require more pieces per m² and typically cost more to install.
❓ FAQ
Q. How much waste allowance should I add?
A. 10% is standard for simple rectangular rooms. Add 15% or more for diagonal installation, complex patterns, or L-shaped spaces. It's always better to have extras since matching the same dye lot later can be difficult.
Q. How do I choose grout width?
A. Small tiles (~300mm) use 2mm, medium (300-600mm) use 2-3mm, large format (600mm+) use 3-5mm. Floor tiles typically use slightly wider grout than wall tiles.
Q. What tile size should I choose?
A. Small tiles (200-300mm) work well in bathrooms, medium (400-600mm) for kitchens/balconies, large format (600mm+) for living room floors. Larger tiles install faster but may have more cutting waste.
Q. How do I find tiles per box?
A. Check product specifications or ask the retailer. 300×300mm tiles typically come 10-12 per box, while 600×600mm tiles usually come 3-4 per box.
Q. What should I do with leftover tiles?
A. Keep a few tiles for future repairs. The same dye lot may be hard to find later, and tiles can vary slightly between production batches.
