How It Works

Carpet tiles (also called carpet squares) are modular, typically 24"x24". They are self-adhesive or use carpet tile adhesive. Individual damaged tiles can be replaced.

The Formula

Tiles = CEIL(Length/Tile Size) x CEIL(Width/Tile Size) + Waste + Spares

Variables

  • Grid — Round up each dimension to the next full tile
  • Waste — 5% for monolithic/quarter-turn, 10% for ashlar
  • Spares — 5% reserve for future replacement

Example

20x15 room with 24" tiles: 10 x 8 = 80 tiles + 5% waste + 5% spares = 88 tiles.

Tips

  • Buy 5% extra and store in a closet for future spot replacement.
  • Quarter-turn pattern hides seams better than monolithic.
  • Use carpet tile adhesive (not glue) — it remains tacky and allows removal.
  • Start from the center of the room for balanced border tiles.
