Premium Tile Calculator

To calculate how many tiles you need, first measure the length and width of each area you want to tile. Multiply these dimensions to get the square footage of each area, then add all areas together. Divide the total square footage by the square footage of a single tile (width × height ÷ 144). Finally, add a waste percentage (typically 10-15%) to account for cutting and breakage. Our calculator automates this entire process for you.

The amount of waste you should add depends on several factors: the complexity of your layout, the size and shape of your tiles, and your experience level. For simple rectangular layouts with large tiles, 10% waste is usually sufficient. For diagonal patterns, intricate designs, or small mosaic tiles, you may need 15-20% waste. Our calculator defaults to 10% but allows you to adjust this percentage based on your specific project needs.

The amount of grout needed depends on the size of your tiles and the width of your grout lines. Larger tiles with narrow grout lines require less grout, while smaller tiles with wider grout lines require more. As a general rule, a 25-pound bag of grout will cover approximately 100-200 square feet, depending on tile size and grout joint width. Our calculator estimates grout needs based on your specific tile dimensions and grout width.

Including labor costs in your tile calculation is essential for budgeting your project accurately. Tile installation costs typically range from $4 to $32 per square foot, depending on the complexity of the job, tile type, and your location. Simple straight-lay installations with standard ceramic tiles cost less, while intricate patterns with natural stone or large-format tiles cost more. Our calculator allows you to input labor costs to get a complete project estimate.

It’s wise to keep extra tiles for future repairs. Tile manufacturers can discontinue styles, and dye lots can vary between production runs, making it difficult to find matching tiles later. We recommend keeping at least 10-15% of your total tile purchase as extras. For example, if your project requires 100 tiles, consider purchasing 110-115 tiles total. This ensures you’ll have matching tiles if you need to replace any that become cracked or damaged over time.
