Tile calculator

How many tiles do I need?

Put in your room sizes and tile. You'll get square metres, tile and box counts, adhesive and grout. No email, no sign-up.

How it works

The sums we use.

1. 01
   Area

   Length times width for each area, added together.
2. 02
   Cuts and breakages

   We add 10% for a straight lay, 12% for brick bond, 15% for herringbone or diagonal and 20% for large format, where more of each tile ends up as offcut.
3. 03
   Adhesive

   Based on the trowel you’d use for that tile size. Bigger tiles need a thicker, fuller bed, so they take more per square metre.
4. 04
   Grout

   Worked out from the joint width, tile size and a typical tile thickness, with 10% on top.

What it doesn't cover

Where a tiler earns their keep.

• Doors, baths, kitchen units and anything else you won’t tile around. Take those off or you’ll over-order.
• Borders, feature strips and mosaics. Measure those separately.
• Pattern matching on patterned or book-matched tiles, which can need a lot more.
• Primer, tanking, levelling compound, trims and silicone.
• Uneven floors. Large format tiles on a floor that isn’t flat use more adhesive than this assumes.
