Calculating how many boxes you need is simple once you know the total area you want to cover and the coverage per box.

 

Quick Formula

(Total Area ÷ Coverage Per Box) + 10% Extra = Total Boxes Needed

 

Step By Step Guide:

Step 1: Measure the Area

• Measure the length and width of the space in metres.
• Formula: Length × Width = Area

 

Example:
A bathroom floor is 3m long and 2m wide.

3m × 2m = 6m²

So, the total area is 6 square metres.

 

Step 2: Check the Box Coverage

• Different tile sizes contain different quantities and coverage per box.
• Always enter the Quantity Per Box.

 

• 30x60cm = 5 tiles per box (0.9sqm)

• 60x60cm = 4 tiles per box (1.44sqm)

• 60x90cm = 1 tile per box (0.54sqm)

• 60x120cm = 2 tiles per box (1.44sqm)

• 80x80cm = 3 tiles per box (1.92sqm)

• 80x160cm = 2 tiles per box (2.56sqm)

• 120x120cm = 2 tiles per box (2.88sqm)

 

Step 3: Divide the Total Area by the Box Coverage

• Always round up to the next full box.

Formula: Total Area ÷ Coverage Per Box = Number of Boxes Needed.

 

Example:
6m² ÷ 1.44m² = 4.16 boxes

So, you would need 5 boxes.

 

Step 4: Add Extra for Waste

• It is recommended to add 10% extra for cuts, breakages, and mistakes.

 

Example:
5 boxes + 10% = 5.5 boxes

Round up again to the next full box.

Final amount needed: 6 boxes
