Floor Tile Calculator

Floor tiles and boxes for any room, with waste set by your layout.

How this works

Floor area is length times width. Waste is about 10% for straight or brick lay, 15% for diagonal and 20% for herringbone, because more tiles get cut at the edges. Boxes are rounded up from the box coverage printed on the pack.
