Tiles rounded up, boxes rounded up — order the full box, keep spares from the same batch.

Ballpark, not gospel. This estimates tiles, boxes, and costs from the numbers you punch in — always check against your supplier's specs and your own measurements before ordering or quoting.

Questions tile contractors actually ask

Straight answers, no fluff. Then run your own numbers above.

How many tiles do I need for a 10x10 room?

A 10×10 room is 100 square feet. With 12×12 tiles (1 square foot each), that's 100 tiles plus 10% waste for cuts — 110 tiles total. Check your box label for square feet per box and round up to full boxes; a typical 12×12 box covers about 10 square feet, so you'd order 11 boxes.

How much extra tile should I order for waste?

Order 10% extra for a straight lay and 15–20% for a diagonal layout or a room with lots of corners — diagonal cuts waste more. Always keep a few spare tiles from the same batch; later batches can differ slightly in shade, which makes repairs obvious.

How many tiles come in a box?

It varies by size and manufacturer — the number that matters is the square footage per box, printed on the box label. Divide your total square feet (with waste) by that number and round up. As a rough guide, 12×12 tiles often come about 10 square feet to a box.

How much does tile installation cost per square foot?

In the US, tile installation labor typically runs $5–$15 per square foot depending on tile size, layout complexity, and region — large-format and diagonal layouts cost more. Materials add roughly $2–$15 per square foot. Run your room through the calculator above for a job-specific number.
