Our products are produced to a 300 x 300 mm module. Accurate metric dimensions shown include the grout allowance of 1.5 mm for wall tile, and 3mm for floor tile. Imperial sizes are nominal and shown to the nearest inch equivalent.
The example shows a 1" x 1" wall tile, the listed size of the tile already includes the grout space. A 2" x 2" wall tile will be 48.5mm (50mm - 1.5mm grout space).
The benefit of our modular sizing system is the ability to easily mix sizes while maintaining a constant width of grout joint.Back to technical
