Tile quantity calculation must go beyond simply calculating the area and accurately reflect the 'effective area' occupied by a single tile and the 'loss' incurred during construction.
It sums up all the areas where actual tiles will be placed. Our calculator allows you to add and manage multiple areas individually.
Calculate the actual area occupied by one tile, including the thickness of the grout between the tiles.
The total number of tiles required is calculated as (Construction Area / Effective Area] × (1 + Markup Rate], and since tiles are sold in boxes, the result is always rounded up.
Installation difficulty and waste rates vary depending on the tile size. Please refer to the general characteristics by standard size.
Large tiles of 600mm or larger are at high risk of breakage when cut and have a large surface area per sheet, so it is standard practice to set a more generous markup rate.
Please enter the information listed on the tile package and actual measurements to calculate the exact quantity required.
This is the actual size of the tile you intend to purchase. (e.g., 300, 600, etc.]
This is the actual number of tiles contained in one box. Since it varies by size, please check the outside of the box.
This is a spare amount to cover cutting loss and breakage. If you are a beginner at DIY installation, we recommend about 15%.
These are the actual measurements of the area where tiles will be laid. You can calculate multiple areas at once, such as the living room and kitchen, using the 'Add' button.
Here are practical tips to prevent material shortages and achieve a clean finish.
Walls and floors are often uneven. You must measure in at least three places and determine the area based on the longest point to ensure you do not run out of tiles.
Leveling the first layer is the key to the construction. If the baseline is misaligned, the tile pieces at the finish will be uniformly sized, compromising the aesthetics.
You must take into account the thickness of the tile adhesive cement (about 5~10mm] in your calculations to prevent a step from forming where it meets the flooring or linoleum.
It is difficult to purchase tiles individually, and there may be color variations between lots. If the calculation result is a decimal, please be sure to add one box to your order.
