20x120 Wood Plank Tile Calculator
A 20x120 cm plank tile covers 0.24 m², so you need about 4.17 tiles per square metre. A 12 m² room takes 50 planks, or 55 with 10% waste.

About 20x120 Wood Plank Tile Calculator
A 20 by 120 centimetre plank tile covers 0.24 square metres, which is 4.17 tiles per square metre. A 4 by 3 metre room of 12 square metres needs 50 tiles before waste and 55 with a 10 percent allowance. The size is preset here so you only enter the floor. This is the classic wood effect plank, and it is laid like floorboards rather than like square tiles, which changes both the pattern and the waste. Long thin porcelain tiles almost always have a slight bow along their length, so laying them with a half offset puts the high middle of one plank next to the low end of its neighbour and leaves visible lips. The usual guidance is an offset of no more than a third of the length, so around 40 centimetres, or a random stagger that never falls below about 20 centimetres between joints in adjacent rows. Laying along the longest wall or towards the main light source makes the floor look most like timber. Allow 10 percent waste for a straight stagger and 15 to 20 percent for herringbone, where every edge piece is an angled cut. Mixing tiles from several boxes as you go spreads the printed grain patterns so repeats are less obvious. For a shorter rectangular format see 30x60 Tile Calculator.

Frequently Asked Questions
How many 20x120 tiles per square metre?
About 4.17, since each plank covers 0.24 square metres. Multiply your area by 4.17 and round up, then add the waste allowance.
How many 20x120 tiles for a 20 square metre room?
About 84 before waste and 92 with a 10 percent allowance. A herringbone layout of the same room would need 15 to 20 percent extra.
What offset should wood plank tiles have?
No more than a third of the plank length, around 40 centimetres here, because long tiles bow slightly and a half offset causes lipping. A random stagger with joints at least 20 centimetres apart also works well.
How much waste for herringbone plank tiles?
Between 15 and 20 percent. Every plank at the edge of a herringbone floor is cut at an angle and the offcuts are seldom reusable.
How do I make plank tiles look like real wood?
Mix planks from several boxes so the printed grain does not repeat side by side, keep grout joints narrow, and use a grout colour close to the tile.
