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)

How to Calculate the Area for a Circular Room?

If the room is circular, start measuring the diameter. So, stretch across your room and measure it. Find the radius and then the area.

For the round area, find the radius by dividing the diameter by 2. Multiply it with pi-3.14. Convert it again into the nearest decimal in square feet.

For example:

If a round-shaped floor has 20 feet diameter, the radius would be 20/2 = 10 feet. We know the area of the circle = radius x radius x pi (3.14).

Here, it’s 10 x 10 x 3.14 = 314sq ft

Finally, you can divide the overall floor area into the single tiles area to calculate the number of tiles required.

Some Pro Tips:

  • Keep your baby or pet away from the site.
  • Ensure you're rolling your measuring tape over the plain surface.
  • If you calculate the number of tiles for the wall, don't forget the doors and windows. Find the areas of these and subtract to get the exact working area.
  • Don't throw the leftover from your tiles. You may need them in the future for any repair.
  • Size is a matter, especially since larger tiles tend to break more. So, consider adding more overage than the average amount.
  • For irregular shapes, make different sections. Measure the areas separately, then add them to get the total area.
  • Be careful before tiling your floor if there is any drain or vanities beneath the floor.
  • Measure twice so that there's no mistake.

Final Words

How to calculate the number of tiles needed for a room was never too complicated. And, you have just read the article!

How about giving a trial run of your latest study? You've got pen and paper. Just get a measuring tape. And, the geometry and the calculator shouldn't be any problem.

FAQ

Here are a few answers to the most common questions to clear the confusion.

How many tiles do I need for a 12x12 room?

For 30 x 60 tiles, you will need around 75 tiles or 10 boxes For 40 x 40 tiles, you will need around 84 tiles or 10 boxes For 60 x 60 tiles, you will need around 38 tiles or 10 boxes You can use the DBL tiles calculator to calculate the number of tiles.

How do you calculate tiles Per Square Meter?

Find the area of the floor. Then find the number of total tiles. Divide the second calculation by the first one, and that's the tile number per sq. meter. For example, a floor's area is 144 sq. meters, and 5760 tiles are needed to cover the floor. The number of tiles per sq. meter will be 5760/144= 40. *This is not necessarily the exact number or calculation. And, sq. feet would be the best as the calculation unit.

What are floor tile sizes available in DBL ceramics?

DBL tiles come in multiple sizes, including: • 30cm x 30cm • 30cm x 60cm • 60cm x 60cm • 40cm x 40cm • 60cm x 120cm
