How does the estimator calculate layout waste?

The tool applies default waste percentages based on the selected layout pattern, such as higher waste for diagonal or herringbone layouts, to account for edge cuts.

Can I calculate grout requirements for rectangular tiles?

Yes, the estimator uses the tile length, width, thickness, and joint dimensions to calculate the total joint volume and grout weight in kilograms.

What packaging options are supported for box calculations?

You can specify packaging either by entering the number of tiles per box or by entering the number of tiles per square meter.

Does the tool round up the final material counts?

Yes, the calculator rounds up tiles and boxes to the nearest whole number so you can order complete packages.

Can I estimate the total cost of my tiling project?

Yes, by entering the tile price per square meter and the grout price per kilogram, the tool provides an optional total cost estimate.

Tile Coverage Estimator

Estimate how many tiles you need to cover a room, including layout-aware waste (straight, 45° diagonal, herringbone, basketweave), boxes to buy, grout volume and weight, and an optional cost total. Enter room and tile dimensions plus joint width to get a ready-to-order material list.

What this tool helps you do

A tiling material estimator for homeowners, tilers, interior designers and building-materials sales:

Room & tile — enter the room length/width and the tile length/width/thickness (square or rectangle tiles supported).
Layout pattern — pick straight (90°), diagonal (45°), herringbone or basketweave. Each carries a different default waste % (diagonal/herringbone waste more).
Grout — set joint width and depth; the tool computes the joint volume and the grout weight in kg (with 10% excess for waste/cleanup).
Pricing (optional) — enter tile price per m² and grout price per kg to get a cost estimate.
Order list — get tiles to order, boxes (if you provide tiles-per-box or tiles-per-m² pack spec), grout bags, and a total cost.

Pure geometry — no external data. Results round up tiles/boxes so you order whole pieces.
