How to Calculate Number of Tiles Needed for a Room?

Are you into a renovation or building a new floor? Or a new home? Then, you must've been rambling many times in choosing the tiles fit for your kitchen, bathroom, and other places.

But you were wondering how many for a room? And how to calculate the number of tiles? Trust me! There's no need for a mathematician. With a simple calculation, you can easily do it yourself.

Let's know-how.

Calculation of How Many Tiles You Need for a Room

The calculation is just a few steps away. Just follow the steps given below, and you are good to go.

Let's get started.

Step 1: Measure the room

If it's a normal quadrilateral, measuring the width and length are enough for calculating the area. Remember, 'feet' will be the best unit for measurement to avoid confusion.

Step 2: Multiply the two measurements

Multiplying the length and width will provide you with the square footage of the project space.

Area of the Room=Room Length x Room Width

Area of a single tile= (Tile length + Grout size) x (Tile width + Grout size)

Step 3: Calculate the number of tiles

You can only purchase tile in boxes. To calculate the number of tiles, you have to divide the floor area by the area of each tile.

Number of tiles = Area of the floor / Area of tile

Example of measuring tiles using DBL tiles calculator:

Below is an example of how to calculate the number of floor tiles using the DBL tiles calculator. We have taken two standard-size tiles from DBL ceramics for calculation.

Let's assume:

• Room Length: 15ft
• Room width: 10ft
• Grout size: 1mm (0.003ft approx.)

For 40cm x 40cm or (2ft x 2ft approx.) tiles:

• Tile area: (40cm+0.1) x (40cm+0.1) = 1608 cm2

or

 1.3156 ft x 1.3156 ft = 1.73sq ft

• Total room area: 15ft x 10ft = 150sq ft
• Number of tiles required: 150sq ft / 1.73ft = 86.71 or 87 tiles
• Number of boxes required: 10 (as each box contains 9 tiles)

For 60cm x 120cm or (2ft x 4ft approx.) tiles:

• Tile area: (60+0.1) x (120+0.1) = 7218cm2

or

1.9717ft + 3.9402ft= 7.77sq ft

• Total room area: 15ft x 10ft = 150sq ft
• Number of tiles required: 150ft/ 7.77ft = 19.31 or 20 tiles
• Number of boxes required: 10 (each box contains 2 tiles)
