A 30x60 cm tile covers 0.18 m², so you need about 5.56 tiles per square metre. A 12 m² room takes 67 tiles, or 74 with 10% waste.

About 30x60 Tile Calculator
A 30 by 60 centimetre tile covers 0.18 square metres, which works out at 5.56 tiles per square metre. A 4 by 3 metre room of 12 square metres needs 67 tiles before waste and 74 with a 10 percent allowance. This page opens with the size already set so you only enter the room. Thirty by sixty is the most widely used rectangular format, on floors and walls alike, and the detail that catches people out is the offset. Laying rectangular tiles in a brick pattern with each row shifted by half a tile looks natural, but long porcelain tiles are rarely perfectly flat along their length and usually have a slight bow. A half offset puts the highest point of one tile next to the lowest point of its neighbour, which creates visible lipping. Tile industry guidance for tiles with any side longer than about 45 centimetres is an offset of no more than a third, so 20 centimetres for this size. Laying in a straight stack bond avoids the issue entirely. Herringbone or diagonal layouts use more cuts, so raise the waste allowance to 15 percent for those.

Frequently Asked Questions
How many 30x60 tiles per square metre?
About 5.56, since each tile covers 0.18 square metres. Multiply your area by 5.56 and round up, then add waste.
How many 30x60 tiles for a 20 square metre room?
About 112 before waste and 123 with a 10 percent allowance. A herringbone layout of the same room would need closer to 15 percent extra.
Should 30x60 tiles be offset by half?
Usually not. Long tiles tend to have a slight bow, and a half offset lines up the high point of one tile with the low point of the next. An offset of a third, about 20 centimetres, is the common recommendation.
Can 30x60 tiles be used on walls?
Yes, they are one of the most common wall formats, laid either horizontally or vertically. Vertical laying makes a ceiling look higher, horizontal makes a narrow room look wider.
How much waste for a herringbone pattern?
Allow around 15 percent rather than 10. Every tile at the edge of a herringbone floor is cut at an angle, and those offcuts are rarely reusable.
