Tile calculator
Room size in feet, tile size in mm. You get the tile count with extra for cutting, and boxes if you know the box quantity.
Enter your room size
Measure the floor in feet, wall to wall. For an L-shaped room, split it into two rectangles and add them up.
An estimate only. Share these numbers with the shop to confirm.
How the numbers work
The step-by-step method, with a worked example, is in our guide on calculating tiles for a room.
How do I measure a room for tiles?
Measure the floor wall to wall in feet, at the widest points. Multiply length by width for the area. Split L-shaped rooms into rectangles and add them.
Why is a 600x600 mm tile not 4 sq ft?
600 mm is about 1.97 ft, so one tile covers about 3.875 sq ft. Using 4 sq ft would leave you a few tiles short on a large floor.
How much extra should I add?
Around 10 percent suits most rooms. Use 5 percent for a simple rectangle with a straight layout, and 15 percent for diagonal layouts or rooms with many corners.
How many tiles are in a box?
It varies by manufacturer, size and thickness. The count is printed on the box, and the shop can tell you for the design you choose.
