Frequently Asked Questions

How is tile quantity calculated?
Divide the total installation area by the area of one tile (including grout spacing). An extra 5-10% is typically added for cuts and breakage.
What grout spacing should I use?
Standard grout spacing is 2-3mm for most tiles. Large-format tiles (600×600mm and above) typically use 3-5mm spacing. The grout width affects the total tile count.
Do diagonal layouts require more tiles?
Yes. Diagonal (diamond) patterns require more edge cuts, so you will need approximately 10-15% more tiles than a standard straight layout.
