How to Work Out Tile Area

Take a surface, write "using an area of 1" along the top of the paper, draw a square, and put an arrow at the 1. Divide the square into 18 parts, and multiply 1 by the length of one of these smaller parts. The total square area is this number multiplied by the square root of 3. Subtract the number you ended up with from the number on the paper, and you have the surface area.


- For round areas, stretch your tape measure through the center of the circle. The tape measure must start at one wall and run through the center of the area until you reach the other side. This total length through the center of your circle is called the diameter. Half of the space’s diameter from the center to each wall is called the radius, which is the number you’ll need in your calculations. (remember in middle school when you thought you’d never use the geometry homework? Now’s your chance!)- Measuring a Shower – Showers can be divided into rectangular sections (which is the easy part), but if you have a niche or a bench, that’s a few extra measurements to keep track of. Separate each section by the tiles you plan to use, grouping by material to calculate the square footage needed for all surfaces. Don’t forget to include the depth of the sides of niches and windows too! If you plan to have border tiles, calculate them the same way you measured for trim above, by measuring the perimeter of the shower area and dividing the number by 12 to determine the total linear feet of border tiles needed for your design!

If the space you want to tile is an unusual shape, draw a picture of the floor plan on a piece of paper, then separate the room into squares or rectangles (like I did in the diagrams on this page). Then measure each squared-off section separately, convert inches to feet (divide by 12; you'll probably end up with a decimal), multiply the length and width of each space, then add all these numbers together to find the total square footage.Let’s say you’re dealing with an L-shaped area. Break it down into smaller sections of squares or rectangles and label each one with a letter. Continue measuring the width and height of each section and then calculating the area for them as individual units as explained in Step 3. Finally, add them together for the total square footage. The more individual spaces you’re measuring to add together, the more overage you’ll want to add to ensure full coverage. If your tiles will be installed straight (meaning the edges will be parallel to the wall) you should factor in at least an extra 5% for wastage. In this case, you will need to multiply the amount of tiles you need for your area by 1.05 to calculate for 5% more than your original estimate. For an extra 6%, multiply your estimate by 1.06; for 7%, multiply your estimate by 1.07, and so on. This will help you to calculate the total amount of tiles you need, wastage included.
