In-depth explanation
Work out tile count from floor or wall area and tile size, with a wastage allowance for cuts and breakage. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
About 10% is common; use more for diagonal layouts or lots of cuts. Enter the area you’re tiling either way.
UK mode uses mm for tiles; US mode uses inches. Tweak the inputs above to compare options, then copy or note the result you need.
