Tile Calculator

For odd-shaped rooms, split the room into simple rectangles, calculate each rectangle separately and add the results together.

No, skirting (the strip of tile along the wall-floor junction) and dado (a wall band, common in kitchens and bathrooms) are usually a different size or finish from the main floor tile. Measure their running length separately and calculate them as their own "room".

The area maths is the same either way — length x width. What usually differs is the wastage: walls with more fittings, switches or windows tend to need a higher wastage allowance than a plain floor, and wall tile boxes often hold a different tile count than floor tile boxes.

Yes. Tile batches (dye lots) vary slightly in shade between production runs, so a tile bought today to replace one broken in two years may not match. Buying one or two extra boxes at the time of your original order, and storing them, is the standard way to guard against this.

It depends on the tile size and collection — larger format tiles come fewer to a box, smaller ones more. Use the "Tiles per box" selector in the result card to match your specific product, or check the box quantity listed on the product page before ordering.

Generally no — only unopened, undamaged boxes in original packaging within our return window can be returned (see our FAQ page for the full return policy). This is exactly why ordering the right quantity, with sensible wastage, matters.

10% is a safe default for a simple rectangular room laid in a standard grid pattern. Increase it to 15-20% for rooms with many corners, diagonal or herringbone laying patterns, stairs, or a lot of cutting around fixtures.
