How to Calculate the Number of Tiles for Different Spaces: A Step-by-Step Guide
21 November 2024
From the floor to a wall or backsplash of any area, planning the tiling project includes calculating the number of tiles needed. This calculation involves so many estimations, ensuring that the proper amount of tile is purchased. This will result in neither waste nor any type of shortage.
This blog will guide you in calculating the number of tiles needed for any space. We have listed below a few steps that will further make things easy.
Step 1: Measure the Area
The initial step involves getting measurements of the area you are tiling. Measure the length and width (or height of tiling walls) of the space in feet or inches.
The area in a rectangle or square shape is actually very simple along the length and breadth.
For example, if you are tiling a floor whose length is 10 ft and the breadth is 12 ft, that will equal 120 square feet.
The more complicated shapes like circles need to have their areas broken up into more manageable areas or use the appropriate formula such as the area for a circle (πr²).
Step 2: Determine the Size of the Tile
Choosing tile sizes comes after calculating the areas of each tile. Typical tile sizes range from 6 x 6 to as large as 12 x 12. But the most important thing here is to calculate the area for each tile.
A 12″ x 12″ tile (1 square foot) is simple: 1 sq ft.
For others, you only multiply the length and width (for example, an 18″x 18″ tile has an area of 2.25 square feet).
Step 3: Calculate the Number of Tiles Needed
To calculate the total number of tiles needed, simply divide the total area of the space by that of one tile. The number yielded will give the exact number of tiles required for covering the area.
For example, let’s consider the situation when tiling a 120 square-foot floor with 12″ x 12″ tiles (each of which covers 1 square foot). Here, you’d ask for 120 tiles.
However, tiles that are cut around edges or corners usually leave a need for extra tiles to account for waste, making it a good idea to estimate some extra tiles. Generally speaking, an estimated extra 10-15% of the calculated amount should suffice.
Step 4: Consider Additional Factors
Tile Layout: When the tiles are to be fitted in a pattern like a diagonal or another design, more tiles would be necessary, to accommodate the cuts that will have to be made.
Uneven Surfaces: Also, if your surface is uneven or slanting, it may incur more requirements in the form of extra tiles or adjustments during the installation process.
Grout Gaps: The width of grout lines doesn’t have much influence on the count of the tiles but it should be kept in mind overall in the planning so as to have a professional finish.
Allow 10% for Breakages as Well as Offcuts
The calculations above, cover the offcuts but do not take into account the breakages, and therefore one should add a slight amount extra, even when the amount does not get used. For most cases, an extra 10% is usually enough to cover breakages and offcuts, thus, one has a few spare tiles from the same batch kept aside in case accidents or damage happen in the future.
Conclusion
So, by following these simple steps and using the formula for calculating the number of tiles, your tiling project will run smoothly and efficiently. Remember to measure carefully, choose the right tiles, and always have a little extra to cover for mistakes and repairs in the future. Happy tiling!
