In Australia, tiles are measured and sold in m². Common residential tile sizes are 300×300mm, 400×400mm, 600×600mm, 600×300mm (plank), and 800×800mm. Large format tiles (600×600mm+) are popular in modern Australian homes.
Always add at least 10% wastage for cuts, breakage, and future repairs. Diagonal layouts require 15% extra. Order all tiles from the same batch number to ensure colour consistency. Grout joint width affects the finished look — rectified tiles can use 2mm joints; natural edge tiles typically need 5mm+.
