Estimate tile quantities for floors and walls
How to Calculate Tiles for Your Project
Accurate tile calculations save money and prevent project delays. Our free tile calculator helps you estimate the exact number of tiles needed for floors, walls, or backsplashes.
Factors That Affect Tile Quantity
- Area size: Measure length and width in feet or meters.
- Tile dimensions: Common sizes include 12×12, 18×18, and 24×24 inches.
- Pattern: Diagonal and herringbone patterns require more tiles.
- Waste factor: Always order 10-20% extra for cuts and breakage.
Tile Pattern Waste Factors
Different laying patterns require different amounts of extra material:
- Straight lay: 10% extra for cuts and breakage
- Brick/offset pattern: 12% extra
- Diagonal (45°): 15% extra
- Herringbone: 15-20% extra
Frequently Asked Questions
How do I calculate how many tiles I need?
Multiply the length by width of your space to get square footage. Divide by the square footage of one tile, then add 10-15% for cuts and waste. Our calculator does this automatically and accounts for your chosen pattern.
How much extra tile should I order?
Order 10% extra for straight patterns, 15% for diagonal, and 15-20% for herringbone. Also consider buying a few extra tiles to keep for future repairs.
How do I calculate tiles for a diagonal pattern?
Diagonal patterns require approximately 15% more tile than straight patterns due to the increased number of cuts along walls and edges. Our calculator adjusts the waste factor automatically when you select diagonal layout.
Should I calculate grout when ordering tiles?
Yes, grout is essential. The amount depends on tile size and grout line width. A 25-pound bag typically covers 100-200 square feet for standard floor tiles with 1/8" grout lines.
How do I measure for wall tiles?
Measure the height and width of each wall section. For backsplashes, measure from countertop to upper cabinets. Our calculator allows you to add multiple areas for comprehensive estimates.
