Tiling a floor can be a meticulous job, so accurate calculations will make it so much easier. By using this handy worksheet and The Home Depot Ceramic Tile Calculator, you’ll know exactly how many tiles you need to get the job done.

• Getting started

  The Home Depot has hundreds of styles to choose from. Once you’ve selected your tile of choice in-store or online, you’re ready to record your floor dimensions and calculate the number of ceramic surface and border tiles you need with The Home Depot Ceramic Tile Calculator.

• Surface dimensions

  • Width:ft.in.
  • Length:ft.in.

  If the room has extra nooks, closets, etc., that will need to be tiled, be sure to make a note of those measurements as well.

• Tiling tips to keep in mind

  • Make sure your floor is flat, level, rigid and clean

  • Dust, oil, wax or grease will prevent the adhesive from working properly

  • Plan your layout so you start with whole tiles working from the center outwards

  • Choosing the wrong adhesive can cause breaking and crumbling. Be sure to use waterproof adhesive in humid rooms such as bathrooms and kitchens

  • Dotting corners with adhesive can actually increase the likelihood of cracking

  • Grouting unevenly or too quickly can result in grout drying before you tile the area

  • Apply sealer after grout has cured a minimum of 3 days

  • Carefully calculate the number of tiles needed. Then purchase 5–10 percent more than calculated to account for breaking and cutting errors.
