How much extra to order

Our standard recommendation is your full quantity plus 10%, ordered at once so the whole job comes from one lot. Diagonal, herringbone, and complex layouts usually need more because of extra cuts.

Your installer knows your space best and should confirm the final quantity before you order.

Getting your estimate right

△
Order extra

We recommend your full quantity plus 10%. Keep leftover tile for future repairs — a later lot may not match.

◆
Measure carefully

Measure each area separately and add them together. Small openings are usually not worth subtracting — ask your installer if you're unsure.

■
Order from one lot

Natural stone varies between lots. Order your full quantity at once. If you reorder later, the new lot may look lighter, darker, or more veined.

□
Layout affects quantity

Diagonal, herringbone, and other decorative layouts usually need more tile than a straight lay because of extra cuts.

☉
Confirm with your installer

This calculator gives an estimate. Your installer has seen your space and should confirm the final quantity before you order.
