Check PEI rating and COF (coefficient of friction)</p> <h3>How do I calculate how many tiles I need?</h3> <p>Measure the area (length × width), divide by individual tile area to get number of tiles, then add 10-15% for waste. Example: 100 sq ft floor with 12&quot; × 12&quot; tiles = 100 tiles + 15% = 115 tiles.</p> <h3>How much extra tile should I buy for waste?</h3> <p>Add 10% for standard layouts, 15% for diagonal patterns, and 15-20% for complex patterns or natural stone. This accounts for cuts, breakage, and future repairs.</p> <h3>How many tiles are in a square foot?</h3> <p>Depends on tile size. 12&quot; × 12&quot; = 1 tile per sq ft. 6&quot; × 6&quot; = 4 tiles per sq ft. 4&quot; × 4&quot; = 9 tiles per sq ft.</p> <h3>How do I calculate tile for a backsplash?</h3> <p>Measure the length of each wall section, multiply by height (usually 18-24 inches), add sections together. Add 10% waste. Example: 20 linear ft × 1.5 ft height = 30 sq ft + 10% = 33 sq ft.</p> <h3>What is the standard waste factor for tile?</h3> <p>10% for standard straight lay, 15% for diagonal layouts, 15-20% for complex patterns like herringbone or when using natural stone with lots of variation.</p> <h3>How do I calculate grout needed?</h3> <p>Use coverage charts based on tile size. For 12&quot; × 12&quot; tiles with 3/8&quot; joints, you need about 25 lbs per 100 sq ft. Add 20% extra. Larger tiles and wider joints need more grout.</p> <h3>Should I buy extra tile for future repairs?</h3> <p>Yes! Always keep 5-10% of your tiles (minimum 5-10 tiles) for future repairs. Dye lots vary, so you can&#39;t match tiles purchased later.</p> <h3>How do I calculate tile for a diagonal pattern?</h3> <p>Calculate square footage as usual, then add 15% waste instead of 10%. Diagonal layouts require more cuts, resulting in more waste.</p> <hr> <h2>Practice Examples</h2> <h3>Example 1: Bathroom Floor</h3> <p><strong>Dimensions:</strong></p> <ul> <li>Length: 8 feet</li> <li>Width: 6 feet</li> <li>Tile size: 12&quot; × 12&quot;</li> </ul> <p><strong>Calculation:</strong></p> <pre><code>Area: 8 × 6 = 48 sq ft Tiles needed: 48 tiles Add 10% waste: 48 × 1.10 = 53 tiles Round up: Buy 55-60 tiles (usually sold in boxes) </code></pre> <h3>Example 2: Kitchen Backsplash</h3> <p><strong>Dimensions:</strong></p> <ul> <li>Wall 1 (range): 10 ft long × 2 ft high</li> <li>Wall 2 (sink): 8 ft long × 1.5 ft high</li> <li>Tile size: 4&quot; × 4&quot; subway tile</li> </ul> <p><strong>Calculation:</strong></p> <pre><code>Wall 1: 10 × 2 = 20 sq ft Wall 2: 8 × 1.5 = 12 sq ft Total area: 32 sq ft
