How Many Tiles Do You Need

Installing tiles, whether on walls or floors, is a type of work that requires a high degree of accuracy. As someone working hard to fix up a certain area, you obviously wouldn’t want to do any big mistake.

It would surely be frustrating to find out half way through the task that you have run out of materials, and equally frustrating to find out that you have a good number of unused tiles, after you have already tiled the entire floor. That would lead to a lot of extra hassle and money wasted.

The most convenient thing for you would be to have a lot of precision with your measurements. And you can do this with just some simple steps of math!

Well, we know that the thought of math might seem a bit daunting to some of you, but please know that it is the smartest thing to do here because these few steps of simple maths will save you quite a bit of time and money. And considering how tiling is just an expensive process overall, getting the calculation right will help you cut through a lot of the extra hassle.

Maybe the idea that you have to go through many complex measurements is holding you back from starting your work. But if you follow the steps right, this should not be a big deal at all!

Just A Bit of Math!

First of all, you will need a few tools to figure out exactly how much space you are dealing with and the number of tiles you will have to buy. This is the list:

  • A measuring tape
  • Calculator
  • Paper
  • Pen or pencil


tile measurement

Once you have all the materials, you will be ready to start measuring. Firstly, step on the side of the floor and measure the sides; this will be the length. If you are working on a wall, measure its height, which is from top to bottom.

Next, measure the length on the other side of the floor. In case of a wall, you will want to measure the width, which is the horizontal distance.

You have to understand that what you are looking for is the square foot of the whole floor or the wall you want to work on. To calculate that, you have to multiply the two numbers you measured out before.

For example, in the case of the wall, you have the height and the width. You will want to multiply the height to the width, and the product of your calculations will be the size of the room in square feet.

By doing this, you will have a clear idea about the size of the room. Now you can convert it into the number of tiles required. You will need prior knowledge of the square footage of each tile to calculate this. For wood look tile installation, the process of measurements might a bit different.


Tile Conversion

For the conversion, divide the total square footage of the surface you want to work on by the total square footage of one tile. So, then you will know how much area each tile will cover, thus, easily coming up with the number of tiles that you will need.

Little Tip 

This is a tip for anyone who is looking to buy tiles for their floor or wall. Buy a little more than the exact amount you will need. This is because, during the installation process, tiles may break or crack, and you might have to cut some up for better fitting. So it’s best to have a few extras around for emergencies. We also suggest you to know about fixing cracked tiles.

Calculating Extra Tiles

Calculating Extra Tiles

If you have a hard time figuring out exactly how many extra tiles you should get, there is a 

simple calculation that you can help you decide. Just increase ten percent on the total square footage of tiles you will need, then add it up with the original number. The result of the addition is the final amount.

Diagonal Placement

Also, if you want to, say, lay the tiles diagonally, a lot more of the tiles will be wasted while installing them. For cases like that, you will have to follow the addition method. 

Extra Area 

At times, walls and floors don’t turn out to be exact squares or rectangles. Some extra areas may be jutting out, making the calculations a little challenging for you. Drainage tile installation can also be tricky, but it’s manageable if you know how to install drainage tile and how deep.

If that happens, you will want to first draw a floor plan on a piece of paper. Then, you can brainstorm and divide up the floor or wall into different, easy- to-work-with shapes. Just make sure to get all the precise measurements, as this process is a little more complex.


If you are looking to renovate, or just decorate a certain space in your house, office, or any other establishment, a little calculation could be a big help. Once you know correctly what to do with your tiles, you can do the whole job yourself.

A lot of the time, a job done by yourself is much better than the use of hired help. If you had been holding back because you were unsure about the size or quantity of the tiles you had to buy, then that hesitation should not be there anymore.

Just follow all the instructions on this article properly, and you will be able to decide what you need and get everything done all by yourself without any extra help!
