Ceramic vs Porcelain Tile: Which Is Better for Your Project?
Ceramic and porcelain are both useful tile materials, but they are not identical. Porcelain is denser and typically has lower water absorption, while ceramic can offer easier cutting, broader decorative choices, and a lower installed cost for many interior applications.
Read the comparison →Mortar vs Thinset: Which Should You Use for Tile?
Masonry mortar and thinset are not interchangeable tile-setting products. Thinset is formulated for bonding tile to an approved substrate, while masonry mortar serves different joints and bedding applications. Choose from the tile and substrate system—not convenience alone.

Our tile calculator helps you determine the exact number of tiles needed for any floor or wall project. Start by measuring the length and width of the area you want to tile. Next, enter the dimensions of the tiles you've chosen (length and width in cm).
If you're using a specific grout joint width, you can factor that in as well for a more accurate count. Enter the cost per tile or per square meter for a complete price estimate. Click "Calculate Now" to see the total number of tiles required, the total area, and the estimated project cost.
Pro Tips for a Perfect Tile Layout
Plan for Cuts and Breakage
Always add 10-15% to your total tile count. This accounts for tiles that break during cutting and ensures you have matching tiles from the same batch if you need to replace one later.
Batch Numbers Matter
When buying tiles, ensure all boxes have the same batch or shade number. Even tiles of the same color can vary slightly between different production runs, which becomes visible once laid.
Frequently Asked Questions
How many tiles are in a box?
The number of tiles per box varies significantly by manufacturer and tile size. Always check the packaging for the "coverage per box" in square meters or square feet to compare with your total area.
What is the standard grout joint width?
For most floor tiles, a 3mm to 5mm grout joint is standard. For wall tiles, a smaller 1.5mm to 2mm joint is often used for a cleaner, more seamless look.
Can I tile over existing tiles?
Yes, but the existing tiles must be firmly bonded to the floor, clean, and perfectly level. You'll also need a specialized "tile-on-tile" adhesive to ensure a strong bond.
