Tile quantity calculator
Measure the room, choose a waste allowance that matches your layout, and the calculator returns the area to order and the number of boxes, always rounded up. Under-ordering is the expensive mistake — a tile batch that runs out cannot always be matched.
Ten percent suits a straightforward layout. Allow 15% for diagonals and 20% for herringbone.
In square feet. Printed on the box, and listed on our product pages.
Choosing the waste allowance
- 10% — straight lay
- A straightforward grid or brick pattern in a rectangular room, with tile sized sensibly for the space.
- 15% — diagonals and offsets
- Diagonal layouts, 45-degree sets, and rooms with many corners, alcoves, or fixtures to cut around.
- 20% — herringbone and patterns
- Herringbone, chevron, and any pattern where every edge tile is a directional cut. Natural stone with strong variation often needs this too, to allow for selection.
Keep a few spare tiles from the same batch after the job. A future repair with a matching tile is trivial; the same repair with a near-match never quite disappears.
