Calculate the number of tiles necessary to cover an area. Each tile is 13.1" x 13.1" (0.333 m x 0.333 m). Width of Area: Length of Area: Units: Feet Meters Round: Up Down Since the tile coverage may differ slightly from the area you intend to cover with tile, you can chose to round the coverage up or down. You can cut tiles to desired size. * Calculation does not include ramp edges 13.1" x 1.6" (33.3 cm x 4 cm). Calculate the area covered by a number of tiles. Each tile is 13.1" x 13.1" (0.333 m x 0.333 m). 9 tiles = 10.76 sq. feet (1 sq. meter). Tiles Across Width: Tiles Along Length: Units: Feet Meters * Calculation does not include ramp edges 13.1" x 1.6" (33.3 cm x 4 cm).
