  "summary": "Convert a room's square footage and box coverage into the number of tile boxes to buy.",
  "description": "Tile is sold by the box, with each box covering a fixed number of square feet printed on the label, so converting a room's area into a box count requires both accurate area measurement and a waste allowance for cuts, breakage, and pattern layout. This calculator divides your room's total square footage by the coverage per box, applies a waste factor (10% is standard for a straight layout, 15%+ for diagonal or herringbone patterns with more angled cuts), and rounds up to a whole box since partial boxes can't be purchased. Buying slightly extra beyond the calculated minimum is also wise for future repairs, since tile runs and dye lots change over time and matching a broken tile years later from a different production run is often visibly impossible. This tool works the same for floor tile, wall tile, and backsplash tile — just adjust the area and per-box coverage to match your specific product's label.",

  "faq": [
    {
      "q": "How much waste factor should I use for tile?",
      "a": "10% is standard for a straight grid layout, while diagonal, herringbone, or rooms with lots of jogs and cutouts should use 15-20% to cover the extra angled cuts and offcuts that can't be reused."
    },
    {
      "q": "Should I buy extra tile beyond the calculated amount for future repairs?",
      "a": "Yes, buying one extra box beyond your waste-adjusted total is a common practice since tile dye lots change between production runs, making it hard to exactly match a replacement years later."
    },
    {
      "q": "How do I find coverage per box?",
      "a": "It's printed directly on the tile box, usually in square feet, and varies by tile size — larger format tiles often have fewer pieces per box but similar or higher total square footage coverage."
    },
    {
      "q": "Does grout line width affect how much tile I need?",
      "a": "Wider grout lines slightly reduce actual tile coverage per square foot of floor since more area is grout rather than tile, but this effect is small enough that the standard waste factor already accounts for it."
