Calculate how many tiles you need for floors, walls, and backsplashes. Get tile count, boxes, grout, and cost estimates.
Whether you are tiling a kitchen backsplash, bathroom floor, or entire living room, accurate tile estimation saves money and prevents delays. Our tile calculator accounts for tile dimensions, grout width, laying pattern, and waste to give you a precise materials list.
Measure the length and width of your area in feet. For irregular spaces, break them into rectangles and add the areas together. Measure at the longest points and round up -- it is always better to have a few extra tiles than to run short mid-project.
Common tile sizes include 6x6, 12x12, 12x24, and 24x24 inches. Larger tiles cover more area per piece but may require a more perfectly level substrate. Mosaic tiles (1x1 or 2x2 on mesh sheets) are flexible for curved surfaces but require more grout and take longer to install.
Grout joints affect both appearance and tile count. Wider grout lines (1/4 inch) create a more traditional look and are more forgiving with slightly irregular handmade tiles. Narrow grout lines (1/16 inch) give a seamless modern appearance but demand precisely sized rectified tiles. The grout width also affects total tile coverage per square foot.
Straight lay is the simplest and most material-efficient pattern. Brick offset (50% stagger) is popular for subway tile and adds visual interest with minimal waste. Diagonal patterns create the illusion of a larger space. Herringbone is a premium look that requires the most cuts and produces the most waste.
Tile costs range from $0.50/sq ft for basic ceramic to $15+/sq ft for natural stone or designer porcelain. Factor in thinset mortar ($15-25 per 50-lb bag covering 75 sq ft), grout ($10-20 per 25-lb bag), backer board for wet areas ($10-15 per sheet), and tools or labor. Professional installation typically adds $4-10 per sq ft.

Measure your area in square feet (length x width). Divide the area by the size of one tile (in sq ft). Add 10-20% for cuts and waste depending on your pattern. For example, a 100 sq ft floor with 12x12 inch tiles needs about 110 tiles (100 + 10% waste).
Order 10% extra for straight lay patterns, 15% for diagonal patterns, and 20% for herringbone. Complex room shapes with many cuts need more. Always keep leftover tiles for future repairs -- matching tiles later can be impossible if the style is discontinued.
For standard 1/8-inch grout lines with 12x12 tiles, plan on about 1 pound of grout per 3 square feet. Wider grout lines, smaller tiles, and thicker tiles all require more grout. A 25-lb bag covers roughly 75-100 sq ft for standard installations.
Large-format tiles (12x24 or larger) actually make small rooms look bigger because there are fewer grout lines. However, smaller tiles (2x2 mosaics) work better for shower floors that need slope. For bathroom floors, 12x12 or 12x24 are popular and practical choices.
Yes. Straight lay is most efficient with about 10% waste. Brick/offset patterns add 12% waste. Diagonal patterns add 15%. Herringbone is the most wasteful at about 20% extra because of the angled cuts along edges.
