Order all tiles from one batch and keep a few spare for repairs later.
How it works
- 1Area = length × width for each floor or wall, added together, minus any area you will not tile.
- 2Tiles = area ÷ the area of one tile, plus the cutting allowance, rounded up.
- 3Boxes = area with allowance ÷ the m² printed on one box, rounded up.
- 4The allowance covers cuts at the edges and a few spare tiles for repairs later. Diagonal and herringbone layouts waste more than straight ones.
Questions
How much extra tile should I buy?
Straight layouts usually need less extra than diagonal or herringbone ones, because there are fewer angled cuts. Rooms with many corners, pillars or steps need more. Ask your tiler what allowance they want for your layout, and keep a few spare tiles from the same batch for future repairs, since a later batch can differ in shade.
How do I measure a room for tiles?
Measure the length and width of each rectangle in metres and add them up. Split L-shaped rooms into two rectangles. For walls, measure width by height and take off doors and windows. Measure twice, and round up to the next centimetre.
Why should all tiles come from one batch?
Tiles from different production batches can vary slightly in colour and size. Buying everything at once, with the allowance included, keeps the floor even. Check the batch code printed on each box before the tiler starts.
