Tile Calculator
Calculate tiles needed for your project with gap and overlap considerations
Tile Calculator
Estimate the total number of tiles needed to cover a floor, roof, wall, or any other surface. The calculation can include gaps (grout lines) or overlaps for more accurate results.

📚 Gap Size
Floor or wall tiles are typically installed with gaps between tiles because the average tile is not perfectly uniform in shape and size and would not fit properly without any gaps. These gaps are most commonly filled with grout. Grout is a form of concrete, and the gap between tiles can range from anywhere between one-sixteenth of an inch to half an inch. Different tile sizes, materials, and design needs all affect the gap size. Using rectified tiles can allow for smaller spacing.
In some cases, such as with roofing tile or wood siding, tiles overlap to prevent leakage. Enter a positive value for gaps or a negative value for overlaps.
Tile Installation Options
Size
Tile size can range anywhere from small mosaics to large slab tiles. Square sizes are the most popular and easiest to install. Larger tiles can make rooms appear bigger due to fewer grout lines, but can result in more wastage.
Material
Common materials include ceramic, porcelain, glass, quarry, and stone. Ceramic and porcelain are cost-effective and versatile. Glass is most commonly used for backsplashes. Quarry tiles provide grip and are often used outdoors. Stone tiles like marble or granite provide unique natural patterns and textures.
Layout Pattern
Common patterns include linear grids with square or rectangular tiles, running bond layouts (like brick walls), and herringbone layouts. Running bond and herringbone layouts typically use more material than linear layouts.
