Estimating Tile Quantities
When measuring for floor tile the rule is:
Waste Factor will vary based upon tile size, layout, configuration of room, patterns, etc. Typical waste factor is about 12%. Add 15% for tile being installed diagonally or for a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Example:
Actual room size 4.5 meters x 3.4 meters (450cm x 340cm)
Room area: 4.5 x 3.4 = 15.3 m² or 450 x 340 = 1530/1000 = 15.3 m²
Total amount required including wastage is calculated by simply multiplying the room area by the recommended waste factor.

The same method is used when measuring walls. Measure the area to be tiled on each wall. Add them together and figure the square meterage. Add your waste factor and this is the amount needed.
Most vertical applications will require trim pieces which have finished edges, this requires a linear measurement. Trim pieces will be used:
1. Where a tiled surface ends on an open wall leaving an exposed tile edge,
2. Where a vertical surface meets a horizontal, like on the edge of a countertop,
3. Where a vertical surface turns a corner, like on the outside corner of a wall.
Trim pieces and decorative tiles are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6″ bullnose, 8″ decorative liner), then the rule is:
Example:
Ten meter exposed edge that needs bullnose = 1000cm.
Using 10cm Trim piece = 1000cm/ 10cm= 100 pieces of bullnose needed
These formulas will help you estimate the quantities you’ll need. You don’t need to worry about that too much however as we will do all of the calculations for you and provide you with a ‘Tile Quantity Order Form ‘ for you to take to the tile shop when you are ready to order.
