Flooring & Tile How Many Tiles for 100 Square Feet?

This example uses a known 100 sq ft area and 12 in by 12 in tiles, then shows tile count and optional box count.

When to use these tools

  • Estimate tile quantity for a floor, backsplash, shower wall, or small room.
  • Convert room dimensions into a waste-adjusted tile count.
  • Check how tile size changes the number of pieces needed.

Common inputs

  • Known area in square feet or room length and width.
  • Tile width and height in inches.
  • Waste factor and optional tiles per box.

FAQ

Do tile calculators include grout or mortar?

No. The tile calculator estimates tile quantity only. Mortar, grout, trim, spacers, and underlayment are separate materials.

What if tile is sold by the box?

Use the tile count first, then divide by the tiles per box or box coverage printed on the package and round up.
