Calculate the number of tiles needed to cover a room, including a wastage allowance for cuts and breakage.
This tool calculates how many tiles you need to cover a room, factoring in tile size and a wastage allowance for cuts and breakage.
Room area divided by area per tile gives the base tile count, which is then increased by the wastage percentage and rounded up to the nearest whole tile.
Enter your room dimensions in meters, tile dimensions in centimeters, and a wastage percentage (10% is typical), then click Calculate.
Example: A 4m by 3m room using 60cm by 60cm tiles needs approximately 37 tiles including a 10% wastage allowance.
Why add a wastage allowance. Cutting tiles around edges and corners creates waste, and having extra tiles avoids running short mid-installation.
Should I buy extra for future repairs. Many people buy 2-3 extra tiles beyond the calculated amount in case of future damage, since exact tile matches can be hard to find later.
