Measure the area that will receive tile. Calculate separate zones when tile size or layout changes. Tile quantity is rounded up before the full-box count is calculated. Check pieces per box, shade, calibre and batch number before ordering. Diagonal layouts, niches and narrow edge cuts can require a larger allowance.
Use the units beside each field. The values in the worked example are starting inputs; replace them with your measurements and the specifications of your material.
