When buying floor tiles for a home, office, shop or commercial building, one of the first questions is how many tiles come in a carton. If you are planning to install 40x40 cm floor tiles, knowing the number of tiles per box helps you estimate the total cost, calculate the required quantity and avoid purchasing too little or too much material.
So, how many tiles are in a box of 40x40? The answer depends on the manufacturer and the coverage stated on the carton. A 40x40 cm tile covers 0.16 square metres. Therefore, if a carton covers 1.28 square metres, it contains 8 tiles. If it covers 1.6 square metres, it contains 10 tiles.
This calculation is useful when shopping for floor tiles in Kenya because different brands and tile collections may use different packaging quantities.
In this guide, we explain how many 40x40 tiles are in a carton, how to calculate tile coverage, how many boxes you need for different room sizes and how much extra material to purchase for cuts and breakages.
The number of 40x40 tiles in a box depends on the manufacturer's packaging and the total square-metre coverage printed on the carton.
A standard 40x40 cm tile measures 0.4 metres by 0.4 metres.
To calculate its coverage:
0.4 × 0.4 = 0.16 square metres.
This means each 40x40 tile covers 0.16 m².
To calculate how many tiles are in a box, divide the carton coverage by 0.16.
Formula:
Number of tiles per box = Carton coverage ÷ 0.16
For example:
| Carton coverage | Calculation | Number of tiles |
|---|---|---|
| 0.80 m² | 0.80 ÷ 0.16 | 5 |
| 0.96 m² | 0.96 ÷ 0.16 | 6 |
| 1.12 m² | 1.12 ÷ 0.16 | 7 |
| 1.28 m² | 1.28 ÷ 0.16 | 8 |
| 1.60 m² | 1.60 ÷ 0.16 | 10 |
| 1.92 m² | 1.92 ÷ 0.16 | 12 |
These are mathematical examples of possible carton coverage quantities, not a claim that every brand uses these packaging sizes.
When asking how many tiles are in a box of 40x40, always check the carton label or confirm the packaging quantity with your tile supplier.
In Kenya, 40x40 floor tiles are available in different designs, finishes and brands. The number of pieces in a carton can vary depending on the product.
Some cartons may contain 6 tiles, while others may contain 8, 10 or 12 tiles, depending on their packaging specifications.
For this reason, do not assume that every 40x40 tile carton contains the same number of pieces.
Before purchasing, check the following details:
Tile dimensions: Confirm that each tile measures 40x40 cm.
Carton coverage: Check how many square metres one box covers.
Pieces per carton: Confirm the actual number of tiles.
Tile finish: Check whether the surface is glossy, matt or textured.
Product batch: Confirm that all cartons are from compatible production batches.
Price per carton: Compare the cost against the square-metre coverage.
If you are comparing different tile brands, calculating the price per square metre gives you a more accurate comparison than looking at the carton price alone.
Ali Glaziers Flooring Solutions can help confirm the number of tiles per carton for the specific brand and design you intend to purchase.
A 40x40 cm tile covers 0.16 square metres.
The calculation is straightforward:
Length: 40 cm = 0.4 metres.
Width: 40 cm = 0.4 metres.
Coverage: 0.4 × 0.4 = 0.16 m².
Therefore:
| Number of tiles | Total coverage |
|---|---|
| 1 | 0.16 m² |
| 5 | 0.80 m² |
| 6 | 0.96 m² |
| 8 | 1.28 m² |
| 10 | 1.60 m² |
| 12 | 1.92 m² |
| 20 | 3.20 m² |
| 25 | 4.00 m² |
| 50 | 8.00 m² |
| 100 | 16.00 m² |
This table helps you understand how many tiles are required to cover a particular floor area.
Remember that these figures represent the theoretical tile surface coverage. They do not include additional allowances for cutting, breakages or wastage during installation.
Knowing how many tiles are in a box of 40x40 is only the first step. You also need to calculate the total floor area and determine how many cartons will cover it.
Follow these five steps.
Use a measuring tape to determine the length of the room in metres.
For example, assume a bedroom measures 4 metres long.
Record the measurement accurately.
Measure the width of the same room.
For example, assume the width is 3 metres.
Multiply the length by the width.
Floor area = Length × Width
Using the example:
4 metres × 3 metres = 12 square metres.
The bedroom has a floor area of 12 m².
For irregularly shaped rooms, divide the floor into smaller rectangular sections, calculate each section separately and add the areas together.
You should not purchase exactly the calculated floor coverage because some tiles may need cutting around walls, corners, doorways and other obstacles.
Additional tiles may also be needed if a tile breaks during transportation or installation.
A common planning allowance is approximately 10% for straightforward layouts. More may be necessary for diagonal patterns, complicated layouts or rooms with many corners.
Using the 12 m² bedroom example:
12 × 10% = 1.2 m².
Total coverage required:
12 + 1.2 = 13.2 m².
Divide the total required coverage by the coverage of one carton.
Assume the selected carton covers 1.28 m².
13.2 ÷ 1.28 = 10.3125 cartons.
You cannot purchase a fraction of a carton, so round up to 11 cartons.
Therefore, for this example, you would need 11 cartons of 40x40 tiles, assuming each carton covers 1.28 m².
Always use the actual carton coverage printed on the product you are buying.
The number of cartons depends on the floor area and packaging quantity.
The following examples assume each carton contains 8 tiles and covers 1.28 m², with an additional 10% allowance.
| Room size | Floor area | Coverage including 10% | Cartons required |
|---|---|---|---|
| 3m × 3m | 9 m² | 9.9 m² | 8 |
| 3m × 4m | 12 m² | 13.2 m² | 11 |
| 4m × 4m | 16 m² | 17.6 m² | 14 |
| 4m × 5m | 20 m² | 22 m² | 18 |
| 5m × 5m | 25 m² | 27.5 m² | 22 |
| 5m × 6m | 30 m² | 33 m² | 26 |
These are illustrative calculations. Actual quantities may vary according to the layout, tile pattern, carton coverage and installation requirements.
A 3m × 3m room has a floor area of 9 m².
Each tile covers 0.16 m².
9 ÷ 0.16 = 56.25 tiles.
After adding 10% for cuts and breakages:
56.25 × 1.10 = 61.875 tiles.
You should plan for at least 62 tiles.
If each carton contains 8 tiles, you would need 8 cartons, giving you 64 tiles.
A 4m × 4m room has a floor area of 16 m².
16 ÷ 0.16 = 100 tiles.
After adding 10%:
100 × 1.10 = 110 tiles.
If each carton contains 8 tiles, you would need 14 cartons, providing 112 tiles.
A 5m × 6m room has a floor area of 30 m².
30 ÷ 0.16 = 187.5 tiles.
After adding 10%:
187.5 × 1.10 = 206.25 tiles.
You should plan for at least 207 tiles.
If each carton contains 8 tiles, you would need 26 cartons, giving you 208 tiles.
These examples demonstrate why it is important to understand both the number of tiles in a carton and the coverage of each box before making a purchase.
If you are tiling an entire house, calculate the floor area of each room separately and then combine the totals.
For example, consider a house with the following rooms:
| Room | Dimensions | Floor area |
|---|---|---|
| Living room | 5m × 4m | 20 m² |
| Bedroom 1 | 4m × 3m | 12 m² |
| Bedroom 2 | 3m × 3m | 9 m² |
| Bedroom 3 | 3m × 3m | 9 m² |
| Kitchen | 3m × 3m | 9 m² |
| Corridor | 4m × 1m | 4 m² |
| Total | 63 m² |
Add a 10% allowance:
63 × 1.10 = 69.3 m².
If each carton covers 1.28 m²:
69.3 ÷ 1.28 = 54.14 cartons.
Round up to 55 cartons.
Therefore, this example house would require 55 cartons of 40x40 tiles, assuming the same tile is used throughout and each carton covers 1.28 m².
For bathrooms, irregular spaces and areas requiring different tile designs, calculate the quantities separately.
Even after calculating the floor area, the final quantity may change because of the room layout and installation method.
A rectangular room is easier to calculate than an irregularly shaped room.
Rooms with alcoves, curved walls, pillars and unusual corners may require more cuts.
Straight tile layouts generally make quantity estimation easier.
Diagonal layouts and decorative patterns may require additional cutting and more wastage.
Tiles can break during transportation, handling and installation.
Purchasing a reasonable extra quantity helps prevent delays when replacements are needed.
Door frames, pillars, drainage points and built-in structures can affect tile placement.
Measure the actual area to be tiled rather than relying only on the room's external dimensions.
Keeping a few spare tiles is useful for future repairs.
If a tile becomes damaged years after installation, the original design or colour may no longer be available.
Keep spare tiles safely and record the product name, design and batch details.
40x40 tiles are a versatile size that can be considered for different residential and commercial applications.
However, suitability depends on the tile's material, finish, durability, slip resistance and intended use.
A 40x40 tile can create a neat, consistent floor pattern in a living room.
Choose a design and finish that complements the furniture, wall colours and lighting.
Consider the expected foot traffic when selecting the tile's quality and surface finish.
These tiles can be used in bedrooms where the selected design complements the overall interior.
Neutral colours and simple patterns can work well in smaller bedrooms.
Kitchen floors need surfaces that are practical to clean and appropriate for areas exposed to spills.
Consider slip resistance, durability and cleaning requirements before choosing a tile.
Small shops, offices and other commercial spaces may also use 40x40 tiles.
For busy areas, pay particular attention to the product's suitability for the expected traffic and maintenance requirements.
Before paying for your tiles, verify the product specifications.
Tile dimensions: Confirm that the tiles are actually 40x40 cm.
Carton coverage: Check how many square metres one carton covers.
Pieces per carton: Confirm how many individual tiles are packed in each box.
Surface finish: Decide whether you need a glossy, matt or textured finish.
Tile suitability: Check whether the tile is intended for floors, walls or both.
Batch consistency: Where possible, purchase sufficient cartons from the same production batch to minimise differences in shade and appearance.
Price per square metre: Compare products using their actual coverage rather than carton price alone.
Delivery arrangements: Confirm the cost and arrangements for transporting the tiles to your site.
These checks are especially important when buying tiles for an entire house or a large commercial project.

The number depends on the manufacturer's packaging. A 40x40 cm tile covers 0.16 m². If a carton covers 1.28 m², it contains 8 tiles. Always confirm the carton coverage before purchasing.
The quantity varies between tile brands and products. A carton may contain different numbers of tiles depending on its total square-metre coverage. Check the packaging label or ask your supplier.
One 40x40 cm tile covers 0.16 square metres. This is calculated by multiplying 0.4 metres by 0.4 metres.
One square metre requires 6.25 tiles mathematically. In practice, you need to purchase whole tiles and allow for cuts and breakages.
If each carton covers 1.28 m², a 12 m² room requires 10 cartons before wastage. Adding 10% gives 13.2 m², meaning you need 11 cartons.
A 4m by 4m room has an area of 16 m². At 0.16 m² per tile, you need 100 tiles before wastage. Add approximately 10% to allow for cutting and breakages.
At 0.16 m² per tile, 100 m² requires 625 tiles before wastage. With a 10% allowance, plan for approximately 688 tiles, rounded up.
Measure the floor's length and width, multiply them to get the area, add an allowance for cuts and breakages, then divide by the square-metre coverage of one carton. Round the result up to a whole carton.
Yes. An additional allowance of around 10% is commonly used for straightforward layouts. More may be needed for diagonal patterns, irregular rooms or complicated installations. Keeping spare tiles also helps with future repairs.
No. Manufacturers use different packaging quantities and carton coverage. Always check the actual product label rather than assuming that all 40x40 tile cartons contain the same number of pieces.
It can be suitable, provided the selected product is designed for floor installation and has an appropriate finish, durability and slip resistance for the kitchen environment.
You can explore floor tile options from Ali Glaziers Flooring Solutions through its online store. Confirm the available designs, carton coverage, price and stock before ordering.
Knowing how many tiles are in a box of 40x40 helps you plan your flooring budget and avoid unnecessary purchases.
The most important calculation is that one 40x40 cm tile covers 0.16 square metres. To find the number of tiles in a carton, divide the carton coverage by 0.16. To determine how many cartons your project needs, measure the floor area, add an allowance for cutting and breakages, and divide by the carton coverage.
Always confirm the actual number of pieces and square-metre coverage for your chosen brand because packaging varies between manufacturers.
If you are planning a flooring project, explore the available floor tiles at Ali Glaziers and confirm the product specifications before placing your order.
Accurate measurements, suitable tile selection and proper quantity planning will help you complete your flooring project with fewer delays and less material wastage.
